Comparison of Immersion Gold and HASL Processes for PCBs

In PCB manufacturing, Immersion Gold and HASL (Hot Air Solder Leveling) are two common surface finishing techniques. Below is a brief comparison of the two:

Process Overview

Immersion Gold: Gold is chemically plated onto the metal surface by immersing the PCB in a gold salt solution, creating a uniform gold layer.

HASL: Tin is applied by melting it and spraying it onto the PCB using high-speed air, forming a tin layer.

Performance Comparison

Electrical Conductivity:

Gold offers superior conductivity compared to tin.

Corrosion Resistance:

Gold has excellent resistance to oxidation and corrosion, while tin is less resistant.

Wear Resistance:

Gold has better wear resistance due to its higher hardness.

Solderability:

Both gold and tin offer good solderability, but gold’s surface is easier to solder.

Appearance:

Gold has a shiny yellow finish, while tin has a silver-white sheen.

Applications

Immersion Gold: Used in high-reliability applications like gold fingers and connectors, where long-term stability is crucial.

HASL: More common in general PCB manufacturing, especially for solder pads and traces, due to its lower cost.

Cost and Environmental Impact

Cost: Gold is more expensive, so immersion gold is costlier than HASL, which uses cheaper tin.

Environmental Impact: Immersion gold requires careful environmental handling, while HASL may face challenges with quality control in dynamic environments.

Conclusion

The choice between Immersion Gold and HASL depends on the specific requirements, such as reliability, cost, and environmental factors. At GREATPCB, we help you select the best option based on your needs to ensure optimal PCB performance.

The boards of modern times are constructed in such a manner to allow the passage of heavy currents. The process involves the generation of high heat. The optimal performance of the board takes place due to the efficient dissipation of heat. You may be unconvinced about the host of benefits that one can derive from electrical applications. In these situations, get in touch with an electrical specialist or a reputed manufacturer. Such companies are known for their supply of reliable components.

 3. Going through the guidelines

 In cases where controlled dielectric needs exist, the heavy boards will require this chemical element. To prevent the occurrence of short circuits space and trace width in heavy boards are increased to a significant extent. Upon request, reliable companies may satisfy customized needs. However, in these cases, the pricing structure is a bit higher. It is a prudent idea to send all the specifications and files you have to a reputed manufacturer for review and for getting a quote. 

 4. About their performance

 Their performance is not affected by processing temperature. The elongation performance is the best. These products can even hold well during hot-melt welding procedures and do not show signs of brittleness when exposed to low temperatures. This chemical element develops a robust non-toxic layer even in the presence of a highly corrosive setup.

5. Unique features

 These products have unique features. So they are appropriate for high-end applications. Some of the advantages are highlighted below:

 · Thermal distribution

 The copper-plated vias have powerful thermal resistance. They are in frequent use in sectors where high frequency and high speed are the need of the hour.

 · Mechanical strength

 These boards have incredible mechanical strength. They add to the robustness of the electrical system.

 · Effective conductor

 They are good conductors. So they play a vital role in the manufacturing of electronic devices. They assist in the joining of different boards together.

Defining Printed Circuit Board Assembly and Ways to do it in 2022

A printed circuit board is an organized board of various electronics components that pass on the electricity to make a device function. Several tech businesses depend on PCBs. The businesses place an order for PCBs to top manufacturers, to get the parts they need. Often, the order is in bulk, as there is usually a huge scale of production. There are different ways of conducting the assembly process of PCB boards. This blog here tries to discuss the broad aspects of the manufacturing process in a detailed manner. Continue reading to know the details related to this topic. 

 The Basic Definition of the Assembly Process

 GreatPCB is a top-notch manufacturer, having expertise in PCB board assembly, using advanced techniques in a flawless, accurate way. The process is all about connecting a wide range of components of the PCB, using a tested non-conductive substrate. From a practical perspective, there are three major ways to do the assembly process of PCBs.

 Surface Mount Assembly Process (SMT)

 The particular technique of Surface Mount Assembly was first developed by the manufacturers and researchers in the 1960s as an effective PCB board assembly procedure. In a couple of decades, the process developed further. There were more innovations in its application. Currently, most of the manufacturing plants implement the techniques of SMT to produce PCBs in bulk. 

 In this process, manufacturers consider components that have metal tabs. These components can be easily soldered on the surface of the circuit boards. The manufacturers use sophisticated soldering methods to perform the task. The main focus of SMT is to attain a higher circuit density, to make the product more efficient. It leads to improved functional features of the electronic device for which the PCB is used. 

 The Technology of Plated-Through-Hole (PTH)

 It is yet another technology that is implemented to manufacture PCBs in bulk. In this case, the components have leads in their bodies. The PCBs under this process have well-defined drilled holes. The dimensions of the holes are decided by the manufacturers, according to industrial requirements and client specifications. 

 The drilled holes on the circuit boards make it practically very convenient to execute the assembly process, without any technical hassles. It saves considerable time for the PCB manufacturer. The level of efficiency is high. The manufacturer inserts the leads of the components through the hills of the circuit board. 

 Electro-Mechanical Assembly Process

 Another term used for the electro-mechanical assembly process is the box-build assembly procedure. Numerous elements are used in this particular process. For example, the manufacturers use wire harnesses extensively. Also, metalwork is used comprehensively at the middle stages of the assembly process. The manufacturer customizes the metalwork to make it appropriate for the process. 

Moulded plastics of various kinds are also integrated into the procedural framework of PCB assembly. The manufacturers perform the task expertly. Moreover, different types of the loom are used to accomplish the manufacturing objectives. The PCBs are nicely assembled with the devices. 

 New Generation Methods

 Manufacturers and researchers constantly try to evolve the assembly process, making it even more efficient, in terms of saving costs and production time. The next big thing in the industry of PCB assembly is extensive use of microelectronics, with robust electronics engineering techniques. Certainly, there are more innovations integrated within the framework of the process.

 Get in touch with a PCB manufacturer

  It is intelligent to directly call a well-known PCB manufacturer and enquire about the details of the production process. You can also write to the manufacturer, placing your queries. A top PCB manufacturer is more than happy to address your questions.
