Ultimate Guide to PCB Testing Methods: Ensuring Quality and Reliability in Your Circuits

In the electronics sector, Printed Circuit Boards (PCBs) are the life-lines of virtually all gadgets that are in use in the modern society. From humble home appliances to gigantic industrial equipment, PCBs are the skeletal framework of hardware organization and connection of circuit elements. It is vital to guarantee the quality and dependability of these fundamental parts – thus enters PCB testing methods. It is our hope that this extensive hand will help identify the most suitable test strategies for PCB testing, why these techniques matter, and how to maximize your circuits’ functionality.

Introduction

Firstly, an increase in the capability of different electronic devices leads to higher necessary requirements to the PCBs used in their production. Performing tests on the PCBs is an essential step in the manufacturing process done to confirm that a given board performs as a unit to the expected levels. This guide aims at explaining various techniques of PCB testing with a view of having a better understanding on how to achieve quality and reliability on the circuits.

Why PCB Testing is Crucial

PCB Testing When it comes to the potential defects on PCBs, there are shorts, opens, and some component placements. They can cause device failure, decline in performance level, and sometimes also pose safety issues. Through high-quality testing regimes, it becomes easier to address problems before they reach the customer, and thus manufacturers will have reliable and efficient products. Key reasons for PCB testing include:

Detecting Manufacturing Defects: Solder bridges, missing and placed in wrong position components, all can be detected in the initial stages easily.

Ensuring Functionality: Ensuring that the PCB does what is wanted and needed when it is in use, and under several conditions.

Quality Assurance: Ensuring that the business meets industry standards, and what clients require of them.

Cost Efficiency: Decreasing the likelihood of rework and recall by identifying possible defects before they get to the customer.

Types of PCB Testing Methods

These are the types of PCB Testing Methods:

Visual Inspection

Technique one as also referred to as the VI or visual inspection is the simplest and basic type of testing done on PCBs. The technique entails inspecting the board with naked eyes for some of the common faults including solder bridges, missing parts, and misalignment issues.

Automated Optical Inspection (AOI)

AOI employs cameras and software algorithms to check PCBs for defects and performs the inspections singly. This method of inspection is far more efficient than the manual inspection and simultaneously versatile enough to identify numerous problems.

X-ray Inspection

Some functions which include examination of features of BPCs that could not be easily inspected include solder joints under components through x-ray inspection. It is especially effective in inspecting defects in BGA (Ball Grid Array) and other various packages as well.

In-Circuit Testing (ICT)

ICT entails applying different voltage across the PCB to checks on the electrical characteristics of the needy part and connections. The use of this method is highly recommended for the identification of functional problems and verification of the circuit’s goodness.

Functional Testing (FCT)

Functional testing evaluates the effectiveness of the PCB pointing to the fact that it can be tested when placed in use. This method enables the certification of that the PCB works as expected under actual environment.

Flying Probe Testing

In flying probe testing, the probes are moved around to test the electrical properties of the created PCB. Lower to medium volume production runs can be made easily by using this technique; hence it is advantageous in this regard.

Boundary Scan Testing

Boundary scan testing also called as JTAG testing extends test circuitry into all the components for testing the connections between them. Although, this method is very efficient for identifying connection problems and faults.

Burn-In Testing

Burn-in testing puts the PCB in a state of operational stress for a long time to capture early-life failures. This aspect makes the method reliable for the long term since it is likely to identify problems that may occur when the equipment is in use for a long time.

Choosing the Right Testing Method

The choice of the appropriate method of PCB testing can be influenced by several factors such as the level of complexity of the PCB and the numbers of boards to be tested as well as the actual costs of the testing process and other features. Consider the following when choosing a testing method:

Board Complexity: Great board densities or component placement can be a determinant as to whether one needs AOI or X-ray inspection.

Production Volume: Applications that are characterized by high volumes can be easily facilitated by ICT while the low to medium volume applications may require flying probe testing.

Budget: Both manual inspection and AOI are favorable for various production volumes, while X-ray and ICT are more expensive at the beginning.

Specific Requirements: There are two types of the test, namely Functional Test and Burn-In Test that should be made so as to attain the long term reliability in applications that are critical.

Best Practices for PCB Testing

Using the best techniques in testing PCBs increases the quality and reliability of the circuits that you are working on. Here are some key practices to follow:

Early Testing: It is recommended to carry out the tests when the product is still in its design and manufacturing phase so that problems can be noted earlier before they reach a very catastrophic level.

Automate Where Possible: Use method such as automation to reduce the time and improve on the quality of the testing.

Regular Calibration: It is necessary to check if all the testing equipment used for calibration are accurate.

Comprehensive Coverage: This way, you will be able to ensure that there are no defects that are not tested as the best testing approach combines all types of testing methods.

Document Everything: Ensure that you keep records of the tests performed, the results obtained, as well as any measures taken to correct the breaches.

Common Challenges and How to Overcome Them

These are the common challenges and how to overcome them:

False Positives/Negatives

Automated testing methods maybe good some times, they give you the results that are either positive or negative and this will lead to unnecessary rework or more alarming leaving critical defects unfound. In order to avoid this, make sure that testing algorithms and testing equipment are updated and fine-tuned from time to time.

Component Access

Some of the testing techniques involve handling parts of the circuit and with high density board this can be very difficult. Some of the ways in which testbench implementation can be avoided are as follows Boundary scan testing and X-ray inspection.

High Costs

Some form of testing such as X-ray and ICT testing is often very costly. The effectiveness must come with reasonable prices; try to combine some of the mentioned approaches to cover all the aspects without spending too much money.

Future Trends in PCB Testing

About the future, it can be stated that its trends will be in fact linked to the tendencies in technologies and expectations towards ever higher quality and quantity of tested PCBs. Key trends to watch include:

AI and Machine Learning: Using of intelligence algorithms and machine learning in testing algorithms to enhance the efficiency and the minimization of false negative or false positives.

IoT and Smart Manufacturing: Higher testing flexibility and opportunities for the continuous test process supervision.

Advanced Imaging Techniques: The need for better techniques that would enhance the detection of defects within a printed circuit.

Environmental Stress Testing: More focus in the testing of PCBs under different environmental pressures in order to improve on its longevity.

Conclusion

Quality and reliability of packaged circuits have to be maintained to contribute positively in any electronic equipment. This paper seeks to explain the common testing techniques for PCB so that PCB manufacturers are able to test and see if they are free from defects and if they are functional. This ultimate guide will give you a full insight on the available options in PCB testing that will enable you make the best decision that will give you perfect circuits.

What is PCB Assembly ?

PCB Assembly manufacturer - Hitech Circuits Co., Limited

 It’s the step in the manufacturing process in which you populate a blank board with the electronic components needed to make it into a functional printed circuit board. It’s these components that make a board into the circuit that enables an electronic product to function. PCB assembly typically takes place via one of two processes:

1. Surface-mount technology

SMT: SMT stands for “Surface Mount Technology“.  The SMT components are very small sizes and comes in various packages like 0201, 0402, 0603, 1608 packages for resistors and capacitors. Similarly for Integrated circuits ICs we have SOIC, TSSOP, QFP and BGA.

The SMT components assembly is very difficult for human hands and can be time taking process so it is mostly done by automated pick and place machine.

2. Through-hole manufacturing

THT: THT stands for “Through hole Technology”. The components with leads and wires, like resistors, capacitors, inductors, PDIP ICs, transformers, transistors, IGBTs, MOSFETS are example.

The component has to be inserted on one side of PCB and pulled by leg on other side and cut the leg and solder it. The THT components assembly is usually done by hand soldering and is relatively easy.

Printed Circuit Board Assembly Techniques

There are only two common PCBA techniques available for use by a PCB designer. The methods are:

1. Automated PCB Assembly Techniques

Generally, this technique employs the use of state of the art machines, which are fully automatic. For example, the surface mount components are worth positioning with the aid of an automated pick and place machine.

Again, reflow soldering is commonly for surface mount components usually done in a reflow oven. An automated solder stencil is also used to apply the solder paste on the PCB.

Finally, high tech inspection machines are used to confirm and check the quality of the PCBA. Some of which include: Automated optical inspection machine (AOI), X-ray inspection machines, etc.

Above all, due to the precise monitoring, control of soldering, no human input and versatile machines.

This technique ensures utmost efficiency, output consistencies, and limits defects.

2. Manual PCB Assembly Techniques

This method is favorite for use with through-hole parts, which needs manual placement on the board. Besides, with these through-hole parts, it’s advisable you use wave soldering. Note that in the through- hole assembly process, you need to place the components and electronics on the PCB.

After that, you use wave soldering to solder the leads. Typically, you will need an individual to insert a component into a marked PTH. Once done, transfer the PCB to the next station where the next person will be on standby tasked with fixing another part.

What are the Benefits of SMT PCB Assembly?

SMT assembly provides many benefits and some of them are as follows:

It can be used to incorporate small components.

In SMT, the components can be placed on both sides of the board.

It assures high component densities.

Fewer holes need to be drilled for surface mounting than through-hole.

It require low initial costs and time for setting up the mass production.

SMT is the simpler and faster-automated assembly when compared to through-hole.

Errors regarding the component placement can be easily rectified. 

Surface mount  PCBs feature strong joints, which can easily withstand vibrations. 

What are the techniques used in Surface Mount Technology?

There are several techniques for the reflow process. After applying the solder paste or a flux mixture on the board and after placing the components, the boards are conveyed to a reflow soldering oven. The techniques used for reflowing soldering include infrared lamps, hot gas convection, fluorocarbon liquids with a high boiling point, and so on.

What are the different testing methods used in SMT PCB Assembly?

Hitech Circuits as the PCB assembly manufacturer, we perform the following testing and inspection to ensure the quality of surface mount PCBs.

Automated Optical Inspection (AOI): This is performed before and after the soldering to identify the component placement, presence, and solder quality.

X-ray Testing: In this type of testing, the operator relies on the X-ray images of the PCB to check the solder joints and lead-less components such as Quad Flat Packs and ball grid arrays, which are generally not visible to naked eyes.

In-Circuit Testing (ICT): This method is used to detect manufacturing defects by testing the electrical properties in the SMT Assembly.

What type of files or documents should I send for SMT PCB Assembly? 

Gerber Files: The file contains all details of physical board layers including solder masks, copper layers, drill data, legends, and so on.  

Bill of Materials (BOM): This contains information on the list of items needed for the PCB manufacturing and the instructions of manufacturing. 

Pick and Place File: This file contains information on all components to be used in the PCB design and their rotation and X-Y coordinates.

The whole process of PCB Assembly

1. Bare board loader machine

The first step in the PCB assembly is to arrange the bare boards on the rack, and the machine will automatically send the boards one by one into the SMT assembly line.

2. Printing solder paste

When PCB on the SMT production line, firstly, we have to print solder paste on it, and the solder paste will be printed on the pads of the PCB. These solder pastes will be melt and solder the electronic parts to the circuit board when it passes through the high-temperature reflow oven.

In addition, when testing new products, some people will use film board/adhesive cardboard instead of solder paste, which can increase the efficiency for adjusting the SMT machines.

3. Solder paste inspection machine(SPI)

Since the quality of solder paste printing is related to the quality of welding of subsequent parts, some SMT factories will use optical machine to check the quality of solder paste after printed the solder paste in order to ensure stable quality. If there any poorly printed solder paste board, we will wash off the solder paste on it and reprint, or remove the excess solder paste if there is redundant solder paste on it.

4. High speed SMT machine

Usually, we will put some small electronic parts (such as small resistors, capacitors, and inductors) to be printed on the circuit board first, and these parts will be slightly stuck by the solder paste just printed on the circuit board, so even if the speed of printing is very fast and the parts on the board will not fall away. But large parts are not suitable for use in such high speed SMT machines, which will slow down the speed of small parts assembly. And the parts will be shifted from the original position due to the rapid movement of the board.

5. Universal SMT machine

Universal SMT machine is also known as "slow machine", it will be assembled some large electronic components, such as BGA IC, connectors, etc., these parts need more accurate positions, so the alignment is very important. Use a camera to take a picture to confirm the position of the parts, so the speed is much slower than High speed SMT machine we taked before. Due to the size of the components here, not all of them are packed in tape and reel, and some may be packed in trays or tubes. But if you want the SMT machine to recognize the trays or tube-shaped packaging materials, you must configure an additional machine.

Generally, traditional SMT machines are using the principle of suction to move electronic parts, and in order to place the parts successfully, and there must be the flat surface on these electronic components for the suction nozzle of the SMT machine to absorb. However, for some electronic parts don’t have a flat surface for these machines, and it is necessary to order special nozzles for these special-shaped parts, or add a flat tape on the parts, or wear a flat cap for thees electronic parts.

6. Manual parts or visual inspection

After assembled all parts by the high speed SMT machine or Universal SMT machine and before going through the high-temperature reflow oven, and we will set up a visual inspection station here and to pick out the deviation parts or missing components boards etc., because we have to use a soldering iron to repair if there are still defectives boards after passing the high-temperature oven, which will affect the quality of the product and will also increase the cost. in addition, for some larger electronic parts or traditional DIP parts or some special reasons cannot be processed by the SMT machine before, they will be manually placed on pcb here.

7. Reflow oven

The purpose of reflow oven is to melt the solder paste and form a non-metallic compound on the component feet and the circuit board, that means to solder electronic components on the circuit board. The temperature rise and fall curves often affect the soldering quality of the entire circuit board. According to the characteristics of the solder materials, usually the reflow oven will set the preheating zone, soaking zone, reflow zone, and cooling zone to achieve the best soldering effect.

For example, the melting point for SAC305 solder paste with lead-free is about 217°C, which means that the temperature of the reflow oven must be higher than the melting points to remelt the solder paste. What's more, the maximum temperature in the reflow furnace should not exceed 250°C, otherwise many parts will be deformed or melted because they cannot withstand such a high temperature.

Basically, after the pcb passed through the reflow oven, the assembly for the entire circuit board is almost complete. If there are hand-soldered parts, we need to transfer to DIP process, and then we have to check the quality after reflow oven by QC department.

8. Automatic optical inspection(AOI)

The main purpose of setting up AOI is because some high density boards can’t be process the following ICT test, so we used AOI inspection to replace it. But even using AOI inspections, there still have the blind spots for such checking, for example, the solder pads under the components cannot be checked by AOI. At present, it can only check whether the parts have side standing issue, missing parts, displacement, polarity direction, solder bridges, lack of soldering etc., but cannot checking the BGA solderability, resistance value, capacitance value, inductance value and other components quality, so far AOI inspection can’t completely replace ICT test.

Therefore, there is still some risk if only AOI inspection is used to replace ICT testing, but ICT test is also not 100% make sure the good quality, we suggest these two ways can be combined with together to make sure the good quality.

9. PCB unloader machine

After the board is fully assembled, it will be retracted to the unloder machine, which has been designed to allow the SMT machine to automatically pick and place the board without damaging the quality for PCB.

10. Visual inspection for finished products

Normally there will be a visual inspection area in our SMT production line whether there is an AOI station or not, and it will help to check if there are any defectives after completed assembled the pcbs. If there is an AOI station, it can reduce the visual inspection worker on our SMT line, and to reduce the potential cost, and because it is still necessary to check some places that cannot be judged by AOI, many SMT factories will provide the mainly visual inspection templates at this station, which is convenient for visual inspection worker to inspect some key parts and polarity for components.

11. DIP process

DIP process is a very important process in the whole PCBA processing, and the processing quality will directly affect the functional for PCBA boards, so it is necessary to pay more attention to the DIP process. There are many preliminary preparations for DIP process. The basic process is to re-process the electronic components first, like to cut the extra pins for some DIP components, our staff received the components according to the BOM list, and will check whether the material part numbers and specifications are correct or not, and performs pre-production pre-processing according to the PCBA samples. The steps are: Use various related equipment (automatic capacitor pins cutting machine, jumper bending machine, diode and triode automatic forming machine, automatic belt forming machine and other machines) for processing.

12. ICT test

Printed Circuit board open/short circuit test (ICT, In-Circuit Test), The purpose of ICT test is mainly to test whether the components and circuits on the printed circuit board are open or short issues. It can also measure the basic characteristics of most components, such as resistance, capacitance, and inductance values to judge whether the functions of these parts are damaged, wrong parts or missing parts etc. after passing through the high-temperature reflow oven.

ICT test machines are divided into advanced and basic machines. The basic ICT test machines are generally called MDA (Manufacturing Defect Analyzer). It’s just to measure the basic characteristics of electronic components and judge open and short circuits issue we talked above.

In addition to all the functions of the basic ICT test machines, for advanced ICT test machine can also test the whole PCBA by using power, start to testing the PCBA boards by setting the program in the test machine. The advantage is that it can simulate the function of the printed circuit board under the actual power-on condition, this test can partly replace the following functional test machine (Function Test). But the cost for the test fixture of this advanced ICT test can probably buy a car, it’s too expensive and we suggest it can be used in mass production products.

13. PCBA function test

Functional testing is to make up for the ICT test, because ICT only tests the open and short circuits on the the PCBA board, and other functions such as BGA and other fuctions are not tested, so it is necessary to use a functional testing machine to test all functions on the whole PCBA board.

14. Cutting board (assembly board de-panel)

Normally, printed circuit boards will be produced in panel, and it will be assembled to increase the efficiency of SMT production. It means several single boards in one panel, such as two-in-one, four-in-one etc. After finished all the pcb assembly process, it needs to be cut into single boards, and for some printed circuit boards with only single boards also need to cut off some redundant board edges.

There are several ways to cut the printed circuit board. You can design the V-cut using the blade cutting machine (Scoring) or directly manually break off the board (not recommended). For more high density circuit boards, it will be used the professional splitting machine or the router to split the board without any damage the electronic components and printed circuit boards, but the cost and working hours will be a little longer.

A Florida traveler accused of attempting to bring in drugs to Orlando International Airport from the Dominican Republic was arrested Monday afternoon.

According to the federal criminal complaint, after getting off a flight from Santo Domingo around 2 p.m., Roman Batista, 38, was passing through U.S. Customs and Border Protection. At some point during the process, an agent noticed “anomalies” with an “unusually heavy” piece of luggage out of his three bags.

The bag was passed through the X-Ray machine, and inside agents saw a portable speaker, with one loose side piece. The suspect claimed that he never took the speaker apart or tampered with it in any way, says the complaint.

Upon further inspection of the apparatus, investigators could see no electronic components inside, just four tightly taped packages that were found to contain a “white powdery substance.”

The substance subsequently tested positive for cocaine, weighing a total of 3.3 kilograms, or about 7 pounds.

Investigators say Batista invoked his right to remain silent and refused to talk without a lawyer present.

The Kissimmee man was arrested and taken to the John E. Polk Correctional Facility in Seminole County, where he is being held on no bond. He is charged with importation of controlled substances and possession with the intent to distribute.

What is the SMT Process for PCB Board Assembly?

The SMT PCB Board assembly process, or Surface Mount Technology process, is a strategy utilized to mount electronic components straightforwardly onto the surface of a printed circuit board (PCB). This advanced method has generally supplanted the more seasoned through-hole strategy due to its productivity, cost-effectiveness, and capacity to oblige miniaturized components. SMT permits for higher circuit densities and littler gadget profiles, making it the standard in today's hardware fabricating industry.

The SMT prepare includes a few basic steps, each planned to guarantee precision, unwavering quality, and execution of the last PCB assembly. These steps are regularly executed in a exceedingly mechanized environment to keep up accuracy and consistency.

1. Solder Paste Application

The to begin with step in the SMT PCB board assembly prepare is the application of solder paste. Solder paste is a blend of minor patch particles and flux. It is connected to the cushions on the PCB where components will be set utilizing a stencil and squeegee. This step is significant since the quality of solder paste application specifically influences the unwavering quality of patch joints.

2. Pick and Place

After the solder paste is connected, the PCB moves to the pick-and-place machine. This computerized framework precisely picks surface mount devices (SMDs) from component reels or plate and places them onto the solder-pasted cushions on the PCB. The speed and accuracy of this machine permit for quick assembly of thickly pressed circuit boards.

3. Reflow Soldering

Once all components are set on the SMT PCB Board, the assembly enters a reflow broiler. The broiler slowly warms the board through a controlled temperature profile. The solder paste dissolves (reflows) and shapes a solid electrical and mechanical bond between the components and the PCB cushions. The board is at that point cooled, setting the connections.

4. Inspection and Quality Control

Post-reflow, the assembly experiences assessment to confirm the quality of the patch joints and adjust component situation. This step frequently incorporates Automated Optical Inspection (AOI), which employments cameras to identify issues such as misalignment, lost components, or patch bridges. For complex assemblies, X-ray assessment may moreover be utilized, particularly to look at covered up patch joints beneath components like BGAs (Ball Grid Arrays).

5. Rework and Repair (on the off chance that needed)

If any surrenders are found amid review, the SMT PCB board may be sent for adjust. Talented specialists utilize revamp stations to expel, supplant, or resolder components as essential. Progressed devices guarantee that revamp does not harm the board or encompassing components.

6. Functional Testing

Finally, the board may go through utilitarian testing, where it is powered up and tried in conditions comparative to real-world utilize. This guarantees the PCB performs as expecting some time recently it moves on to last item assembly or shipping.

In conclusion, the SMT prepare for PCB board assembly is a profoundly exact and effective strategy that empowers the generation of compact, high-performance electronic devices. From solder paste printing to reflow fastening and testing, each organize plays a crucial part in the creation of dependable and strong SMT PCB sheets that control today’s progressed advances.

Laser welding, however, is known for its low heat input, which makes it ideal for micro-scale projects like circuit boards and sensors. This micro laser welding technique ensures minimal thermal distortion, enabling precise welds with reduced risk of damage to nearby materials.

Additionally, laser welding provides pinpoint accuracy, which is crucial in assembling small-scale devices in the electronics industry. The minimal spatter and heat-affected zones ensure components maintain their integrity and performance.

Challenges and Solutions in Welding Aluminum to Stainless Steel

Laser Welding aluminum to stainless steel is notoriously difficult due to their differing thermal conductivities and melting points. One of the biggest challenges is the formation of brittle intermetallic compounds that weaken the joint.

To overcome these issues, fabricators often use filler metals like Al-Si alloys to create a buffer that prevents direct fusion between the dissimilar metals. Surface preparation is also crucial to remove oxide layers, especially from aluminum, which has a naturally forming, heat-resistant surface layer. Using the right laser welding aluminum settings—often with pulsed lasers—helps limit intermixing and minimizes thermal stress.

Material Considerations: Conductivity, Thickness, and Sensitivity

When welding materials as different as aluminum and stainless steel—or when dealing with sensitive electronics—it's critical to factor in:

Electrical and thermal conductivity: Aluminum conducts heat quickly, while stainless steel holds it, creating uneven expansion.

Material thickness: Thinner materials are more prone to warping and require controlled energy input.

Component sensitivity: Electronics like sensors and microchips demand precision to avoid overheating and failure.

These factors underline the need for precision welding techniques that can be customized for each application.

Laser Types and Settings for Different Applications

Not all laser systems perform equally. The choice between fiber lasers, diode, or CO₂ lasers depends on the application:

Fiber lasers: Ideal for dissimilar metal welding and reflective materials like aluminum and copper. They're energy-efficient and offer high beam quality.

Diode lasers: Great for lower-power applications and plastic welding.

CO₂ lasers: Suited for non-metal materials, though less common in precision metal welding.

When it comes to operation mode, pulsed lasers offer better control over heat input for micro applications, while continuous wave lasers are preferred for deep, high-speed welds.

Quality Control and Inspection for Micro-Welds

Quality assurance is critical in applications like laser welding electronics or medical devices. Techniques used for inspection include:

Non-destructive testing (NDT): Ensures weld integrity without damaging the part.

Visual inspection: Identifies surface-level defects like cracks or undercuts.

X-ray analysis: Used for internal inspection of micro welds, particularly in aerospace and defense applications.

These methods help guarantee that joining dissimilar metals or welding fine electronics meets strict industry standards.

Industries Benefiting from These Laser Welding Methods

Several high-precision sectors benefit from these advanced laser welding solutions:

Automotive: For battery tabs, sensors, and lightweight metal joints

Aerospace: For secure, minimal-weight joints in critical components

Electronics: Micro-welding for circuit boards and miniaturized devices

Medical devices: For sterile, accurate welding in surgical instruments and implants

Best Practices to Ensure Strong, Clean Laser Welds

To get the most from laser welding, consider these best practices:

Surface Preparation: Clean metal surfaces to remove oxides and contaminants.

Joint Design: Use lap joints or tailored geometries to reduce stress points.

Shielding Gas: Use argon or nitrogen to prevent oxidation during the weld.

Combining these strategies ensures stronger, more consistent results—especially when working with welding stainless steel with laser or handling sensitive micro laser welding operations.

Laser welding is no longer limited to simple welds; it's a cornerstone of precision manufacturing. Whether you're joining two drastically different metals or working with intricate electronics, laser welding electronics and dissimilar metal welding offer unparalleled flexibility, speed, and reliability.
