RoHS Compliant PCB Manufacturing — Essential Resources in USA

RoHS compliant PCBs are common in the PCB industry. RoHS is an acronym for Restriction of Hazardous Substances, and it is a directive from the European Union, which they introduced as 2002/95/EC, in the year 2002. The directive prohibits the use of six hazardous substances, such as:

Lead

Mercury

Cadmium

Hexavalent Chromium

Polybrominated Biphenyl

Polybrominated Diphenyl

The objective of the directive is to focus on the environment-friendly production of components for the electrical and electronic industry. Therefore, for circuit board manufacturers in the USA and elsewhere, making RoHS compliant PCBs means using environment-friendly alternatives for the substances prohibited by the directive. As the demand for RoHS compliant PCB boards increases in the countries belonging to the European Union, circuit board manufacturers supplying to these countries must adhere to the directive.

With rapid replacement of electronic devices, most discarded electronics is ending up in landfills. Hazardous substances like lead, present in conventional PCBs, pose a grave threat to the environment. This is the basic cause for concern that the RoHS directive has set out to address. Most organizations are now preparing to avoid the use of hazardous substances by opting for the RoHS compliance.

Why Opt for Lead-Free PCBs?

There are several reasons that indicate opting for lead-free PCB board is advantageous:

Lead is Harmful to Humans: People manufacturing printed circuit boards must necessarily be in direct contact with solder. As solder contains lead, it enters the human body through eyes, nose, and mouth, as solder fumes. Presence of lead in the human body is hazardous to health, and as a safety precaution, safer products must replace lead.

Lead is Harmful to the Environment: As about 4% of landfill waste consists of electronics, the presence of lead therein has a very wide effect on the environment. At present, many thousands of tons of lead-based electronic products occupy landfills. The presence of acidic rainfall further aggravates the situation by leaching the lead from the electronics into the soil. This contaminates not only the soil, but also the groundwater system that irrigates our crops, and ultimately reaches us.

RoHS Compliance Leads to Lead-Free PCBs: Industries opting for RoHS compliance must use lead-free PCBs for their RoHS compliant products.

With increasing use of electronic products in our lives, it is essential that we protect ourselves from hazardous substances threatening our lives. Therefore, all electronic PCB manufacturers must comply with the RoHS directives to save the environment.

Essential Resources for Manufacturing RoHS Compliant 1–20 Layer PCBs

PCB manufacturers consider manufacturing boards up to 4 layers as convenient. However, with the progress of technology, 20-layer boards are now common, but their design and manufacturing is more complicated. As PCB manufacturers prefer a process with a layer-focus for fabricating boards, making 6+ layer boards falls under a category that the manufacturers call complex multilayer PCBs. The design of these complex multilayer boards can encompass various criteria.

In complying with the RoHS directive, the PCB board designer must consider multiple factors when designing boards. This is apart from the basic requirement that the PCB material must not absorb moisture, and the absence of lead must not lead to a loss of soldering strength. Essentially, the resources necessary for manufacturing RoHS compliant 1–20 layer printed circuit boards includes:

RoHS Compliant PCB Material: Manufacturers must use RoHS compliant PCB materials when fabricating printed circuit boards.

Some popular substrate/laminate materials include:

FR370HR

IS410

Polyclad370HR

IsolaFR415

Some important characteristics of lead-free materials used in the preparation of laminates and prepreg include:

T-260

Td

T-288

RoHS Compliant Solder Paste: Also known as lead-free solder material, it typically consists of lead-free solder and flux. Commercial lead-free solder can have various compositions or % weight of metals like Tin (the main element), and Silver, Copper, Antimony, Cobalt, Bismuth, Nickel, Zinc, Indium, Germanium, and other rare-earth elements. The actual composition decides the properties of the solder paste.

For instance, solder paste SAC305 with 96.5% Tin, 3% Silver, 0.5% Copper, offers high strength and thermal fatigue. Although it has a low melting point, it is not eutectic, and rapidly attacks stainless steel in stencils.

Solder paste SN100C with 99.3% Tin, 0.7% Copper, 0.06% Nickel, and 0.005% Germanium, is eutectic with a well-defined melting point.

RoHS Compliant Stencils: It is important that manufacturers use stencils made of material that does not contain any of the six hazardous substances that the RoHS directive prohibits.

RoHS Compliant Surface Finish: Board manufacturers add surface finish to their PCBs for improving their aesthetic value and enhance their shelf-life and soldering capabilities.

Many board manufacturers prefer using SN100CL as lead-free HASL surface finish. SN100CL consists of 99.3% Sn, 0.6% Cu, and a small amount of Ni. The major advantage of using SN100CL is it provides a highly uniform and flat surface, and superior wetting that enables very fine-pitch soldering.

RoHS Compliant Soldermask and Legend Inks: Board manufacturers must use RoHS compliant solder mask and legend inks for solder mask and legend printing on their boards.

Experienced PCB manufacturers typically use the above resources for making RoHS compliant complex multilayer printed circuit boards.

Differences between Leaded Solder and Lead-Free Solder

Leaded solder essentially consists of lead and tin as the major ingredients. That is why it is also known as SnPb solder. However, increasingly, the occupational risk of lead is coming to the fore. Dust and fumes associated with lead soldering have been proven to be toxic when inhaled. All this has made lead solder a documented health hazard.

Solder without lead, or lead-free solder, has now come to replace conventional leaded solder. Lead-free solder comprises many substances, in varying proportions, like:

Tin

Silver

Copper

Nickel

Bismuth

Zinc

Antimony

Major components of some common lead-free solders are:

Tin-Silver: The silver increases the electrical conductivity, while also acting as a catalyst. The presence of tin improves the mechanical strength of the solder, while also acting as a protective agent and reducing corrosion possibilities.

Tin-Copper: Presence of copper increases the mechanical strength and the electrical conductivity

Tin-Zinc: Presence of zinc helps lower the melting point of the solder.

Advantages and Disadvantages of Leaded Solder

Leaded solder offers several advantages:

Strong joint formation

Melts at lower temperature

Good electrical conductivity

Ease of use

Fewer quality problems

Strong wetting

Longer shelf life

Disadvantages of lead solder:

High toxicity

Advantages and Disadvantages of Lead-Free Solder

Advantages of lead-free solder:

Environmentally friendly

Non-hazardous to human health

Good quality of soldering

Disadvantages of lead-free solder:

Higher melting point

Although leaded solder joints look more shiny and clean, and lead-free solder looks rather gray and dull, this is more due to slower wetting in lead-free solder on PCB boards. However, manufacturers using lead-free solder find it to offer better PCB soldering. As lead-free solder does not spread during reflow, it results in better soldering joints. Moreover, lead-free soldering does not lead to the rapid stencil wear that comes from leaded solder use. Use of lead-free solder results in more reliable solder joints as compared to those from leaded solder joints.

Conclusion

In electronic products, reliability is a major issue. Solder joints must be reliable, and they must not act as heat intermediaries. To ensure reliability of solder joints it is necessary to consider the type of solder that works best with the application on hand, while considering factors such as ease of use, wiring requirements, cost, and safety. A reliable circuit board manufacturer can provide RoHS compliant printed circuit boards without sacrificing quality or the time to market.

PCB Panel Design Guidelines For Trouble-free Product Manufacturing!

The proper PCB Panel design of a panel is crucial to guarantee the production of error-free PCBs. A panel typically contains multiple PCBs arranged in an optimal manner. Panelization offers various benefits such as time and cost-effective production, standardization, and increased protection for each individual circuit board. Panelizing circuit boards saves time and increases efficiency by processing multiple boards simultaneously instead of individually. Panel assembly can be either homogeneous or heterogeneous. In a homogenous assembly, the panel comprises only one type of circuit board. Conversely, a heterogenous assembly contains a combination of different standard circuit boards in a specific ratio. 

To achieve a successful and cost-effective design of the PCB panel, it is crucial to adhere to specific guidelines:

Size of the Panel:

When designing a PCB panel, size must be considered for effective handling by machines like pick-and-place or AOI. Panels less than 2 inches may cause problems with machines, but can be fixed with extra PCBs or free space around the edges. Note the maximum panel dimensions, typically 12" x 18" (305 mm x 460 mm).

Form of the panel:

For irregularly shaped PCBs, it's important to create a handling edge. This is because automated machines like milling machines and saws are designed to work with standard, geometric shapes. A handling edge provides a reference point for machines to handle and manipulate PCBs during manufacturing. This helps ensure the accuracy and precision of the finished product. 

Margin for the panel handling:

Leaving a narrow strip of free space around the edges ensures safe & secure transportation of panels. The recommended width for this strip depends on the type of PCB structure being transported. For single-sided or double-sided structures, a minimum edge width of 12.5 mm is sufficient. However, for multilayer boards, a wider edge of 25 mm is necessary to provide additional support and stability during transportation. This precaution protects the board during transit from potential damage caused by external impacts or forces.

Distance between PCBs:

The distance between individual circuit boards during the manufacturing process depends on the specific separation method being used. Laser de-paneling enables closer board spacing, usually just a few hundred micrometers. When milling is used to separate boards, a 2-3 mm distance must be maintained between them. Laser de-paneling is a non-contact process that can separate boards close to each other without damage.

Distance between cutting edge and components:

Maintain distance between the cutting edge and mounted components when cutting PCBs in manufacturing. Required distance depends on component height to avoid damage. The appropriate distance may vary depending on the specific cutting method and tools being used. Contact-based cutting methods require operators to maintain a greater distance to avoid damaging or knocking off components.

Cutting Process:

Preparing the PCB panel Design according to the specific cutting method being used is an important step in the manufacturing process. One such method is the use of breakout-tabs, which involves adding tabs to the panel to facilitate separation of the individual boards after the cutting process. By preparing the panel in advance with these tabs, manufacturers can increase the speed and efficiency of the cutting process, ultimately reducing the overall throughput time. The cutting method should be given careful consideration for each panel to ensure the highest quality and most efficient production.

Process Comparison of the Ceramic Substrate

The ceramic substrate is a kind of circuit board. It has a thermal expansion coefficient close to that of semiconductors and high heat resistance. It is suitable for products with high heat generation (high-brightness LED, solar energy), and its excellent weather resistance is more suitable for harsh outdoor environments. Because it has the characteristics of lead-free, non-toxic, and good chemical stability, it will not cause harm to environmental protection, so it is more and more widely accepted by the public. Due to different processes, the ceramic substrate is mainly divided into DBC (Direct Bonded Copper), DPC (Direct Plated Copper), AMB (Active Metal Brazing), and Thick film. We will introduce each of the processes and the advantages, disadvantages of each process. DBC (Direct Bonded Copper) It is composed of the ceramic substrate, bonding layer, and conductive layer. It refers to the special process of copper foil directly bonding to alumina or aluminum nitride ceramic substrate surface at high temperature. The advantages are as below: - The copper layer is thick; - The processing is fast; - The price is cheap; - Can make multilayer; - Suitable for large area consumption; - High thermal conductivity; - High adhesion strength; - Excellent soft brazing; - Excellent electrical insulation The disadvantages are as below: - Can not pass through the hole; - Poor accuracy; - Low flatness (surface roughness); - Suitable for the device in the large distance of the product, can not be done in the precise occupation. DPC (Direct Plated Copper) Mainly by evaporation, magnetron sputtering and other surface deposition process to carry on the substrate surface metallization, first under the condition of vacuum sputtering, titanium, and then is copper particles, the plating thickness, then finish making line with ordinary PCB craft, and then to plating/electroless deposition way to increase the thickness of the line, the preparation of DPC way contains vacuum coating, wet deposition, Exposure development, etching, and other processes. The advantages are as below: - In terms of shape processing, DPC ceramic plate needs to be cut by laser, the traditional drilling and milling machine, and punch machine can not be accurately processed, so the combined force and line width are also finer. - The crystal performance of the metal is good; - The flatness is good; - The line is not easy to fall off; - The line position is more accurate, the line distance is smaller, reliable, and stable, can be through the hole and other advantages. The disadvantages are as below: It can only make a thin plate (thickness AMB (Active Metal Brazing) It is a method to realize the bonding of ceramic and metal by reacting a small number of active elements Ti and Zr in filler metal with ceramics to form a reaction layer that can be wetted by liquid filler metal. The advantages are as below: The combination is achieved by the chemical reaction between ceramic and active metal solder paste at high temperatures, so its bonding strength is higher and reliability is better. The disadvantages are as below: The reliability of the AMB process depends largely on the composition of active filler metal, brazing process, brazing layer structure, and many other key factors. Thick film Thick film technology is straight on ceramic substrate printed graphics, then direct sintering process. The advantages are as below: - The bonding force with ceramic is much greater than that of the DPC process; - It is direct printing of graphics, no etching, and copper plating process, so the cost will be lower; - It is a one-time forming, so the flatness is smoother than that of the DPC. The disadvantages are as below: Because the thick film process is printed, it is generally not too thick. Due to different product requirements, different materials have a certain impact on the conductivity of the film. So it is hard to say which process is best, it depends on the customer’s application and usage, customer could choose each of the processes according to their requirements.

Circuit Board Design & Assembly Process

1. Prepare production files

The preparation of production files is divided into two steps, including not only PCB design (layout) engineers, but also engineering reviewers from PCB factory.

First of all, regardless of whether the PCB design software is AD, Allegro or PADS, when the PCB Layout is about to be interactively produced, it is recommended to output the PCB file as Gerber for data confidentiality and actual production needs.

Gerber is currently the most common practice in the circuit board industry. The most common data format for Gerber data is RS-274-X. Simply put, it is the industry standard.

From the perspective of the PCB layout engineers, the task is completed at this step. And the rest thing is left to the factory.

After the Gerber file is packaged and sent to the board factory, it will not be directly produced. After all, the board factory is also afraid of a bunch of problems in the customer's design that exceed their processing capabilities. For instance, if the line spacing is too small, direct production is likely to be short circuit. In case of a short circuit between the power supply and GND, the entire circuit board will spark with lightning after power-on.

Therefore, after the board factory obtains the customer's Gerber file, it also need to review the production data, which is the reason why the production cost includes the engineering cost.

Board manufacturers usually use Genesis2000 to review Gerber file. (PS: Genesis2000 is mainly used by board manufacturers. If an engineer wants to check his Gerber, it is enough to learn a CAM350, there is no need to learn Genesis2000.)

The data review includes manufacturability inspection ( such as line width, line spacing, solder mask bridge, silk screen, etc.), electrical performance inspection ( like IPC netlist comparison), and at the same time, in the light of the requirements of the customer, combined with the factory's own situation to adjust the file ( such as adjust the line width or stack up based on impedance requirements).

That’s to say, when the CAM review is completed, the data is handled, and the preliminary preparations have been completed here.

2. Manufacture circuit board

Circuit board manufacturing is a complicated process, and the overall process is roughly as follows:

The above picture is the production process of the multilayer board; If it is a double-sided board, the part circled in the red wire frame can be omitted. There are more than 20 steps in total. In order to make it easier for everyone to understand, we simplify the process and only list the key steps.

1. The copper-clad board should be dried and then cut into small pieces for production;

2. Corroded the inner circuit;

3. Perform pressing to combine the substrate and copper foil;

4. Drill holes, and then sink copper to make the vias have electrical properties;

5. Making the outer circuit;

6. Secondary copper, increase conductivity;

7. Printing green solder mask (black solder mask, white solder mask, red solder mask, colorful solder mask);

8. Printing silk screen;

9. Surface treatment;

10. Forming (V-CUT, Routing, etc.);

11. Test (flying probe test, impedance test, metallographic section analysis, etc.);

The above listed items are simplified procedures, but it doesn’t mean that the steps that are not introduced are not important. In the actual production process, every step has its necessity. In order to catch up with the efficiency;However, some bad board factories will compress some steps, such as reduce or just remove the high-temperature baking time, which lead to some boards suffer from blistering and cracking of the copper skin during welding.

3.Produce circuit board

PCB production is in the factory, and for plenty of circuit design engineers, they are not really have opportunities to contact. However, a general understanding of PCB production and a reasonable estimate of the problems that may occur in the production process can make the design more reliable.

Given a couple of small examples to illustrate:

1. Since the circuit is formed by etching, the actual line width may differ from the ideal value. Usually the line width below 10mil is ±1mil, and the line width above 10mi is ±10%. Meanwhile, the etching factor will also affect the upper and lower line widths of the traces. Therefore, when calculating the impedance, the upper line width of the outer layer is about 1 mil smaller than the lower line width, and the value of the inner layer is about 0.5 mil.

2. Although the multi-layer board has rake holes for alignment, there are still errors during pressing, so it will form layer deviation, and which can reach 3mil in some extreme cases. This may cause the traces of the upper and lower layers to overlap or deviate from the reference plane.

3. There are two mainstream silk screen production methods, one is inkjet and the other is printing by making silk screens. For the latter, the position of silk-screen printing will have a larger error. This is also the reason why precise positioning cannot be done through silk screen printing.

What is a Printed Circuit Board?

A Printed Circuit Board or PCB is essentially a board that connects electronic components. It is the basic building block of any electronic design and has developed over the years into a very sophisticated component.The Printed Circuit Board was born, opening the door to smaller, simpler and less cumbersome designs.

PCBs have moved from 1 layer boards to the 20 + layer boards found in your smartphone. They have interconnecting layers that allow the overall size to be reduced – think of mobile phones in the 80s versus the smart phones of today.

To describe how a PCB is created, we’ve taken a standard 2 Layer or Double Sided PCB. Using DesignSpark PCB Software to design your PCB, Gerber and NcDrill files are created. Each Gerber file represents a component necessary for PCB Manufacture including the copper layers, soldermask and silkscreen data, the PCB outline and the solder paste data for producing a laser stencil for assembly. The NcDrill file defines the location and size of each hole on the PCB both PTH (pin through hole) and NPTH (non pin through hole).

The double sided PCB is made of epoxy glass (FR4) with copper foil on both sides of the epoxy glass. This is generally bought pre-prepared from suppliers. The FR4 material is fibreglass and gives the board its rigidity. To create multilayered PCBs combinations of the pre-made material are pressed together with other layers or non-copper clad FR4 (Prepreg) used to isolate the copper layers from each other.

In the PCB design stage, using the DesignSpark software, a drill or DRL file is created. This is the drill file containing the information used to drill the necessary holes.

At this point there is no electrical connection between the layers. The hole walls need to layered with copper. As the walls are non-conductive, a layer of copper is deposited chemically over the hole walls. This process, known as electroplating, is repeated until the copper thickness reached is optimum for connectivity, typically 25um.

The board is covered with photo-resist. This is a soft, photo-sensitive material. The copper film is placed over the board, aligned with the drills and the board is exposed to UV light. The unexposed areas of resist are removed by passing the boards through a developer solution leaving the copper track\pad pattern visible on the board.

The next step is the deposit a coating over the exposed copper, this coating protects the copper on vias, component holes and traces from being removed during the etching stage.  

The photo-resist is stripped (chemically), from the board. It is now time to remove all the copper chemically. The chemical will only remove the copper and not the copper protected by the coating. Now the coating is removed, exposing all the traces and component pads, vias, etc. This is the fundamental PCB circuitry.

A layer of soldermask is added to both sides.  It is generally green, although other colours are common. Using a similar process to the photo-resist, the areas for soldering are exposed.  

The soldermask insulates the copper and will only create a contact where it is exposed. It also acts as a protector against oxidation & corrosion of the copper. The soldermask layers will include clearances around traces, vias, etc. 

To identify the PCB, often developers like to add print to the PCB. This silk-screen will be added at this stage using epoxy ink. Typically, this is white, although many coloured options are available.

A layer of gold, silver or solder on the copper pads will be applied to all component pads, vias, etc., giving the expected finish for the customer. This improves the solderability and protects these surfaces from oxidation. This is the final surface finish.

We use a global panel of proven PCB manufacturers to get the best technology, at the best price, in the best time.
