Steady Performance PCBTok’s Immersion Tin PCB
Immersion tin PCB is a kind of surface plating that can be used for PCBs. The immersion tin process is the most common process for immersion tin. The entire board is immersed in a bath containing tin salts and liquid or gaseous organotin compounds.
During the process, tin atoms are deposited on the surface of the copper substrate as a thin film. A major advantage of this process is that it does not require organic solvents to clean up after processing, so it has low toxicity compared with other processes such as electroless plating or electroplating.
With its ability to withstand high temperatures and resist corrosion, this board is ideal for applications that require consistent performance in extreme environments. It also comes with an improved solder mask design that provides better reliability, especially during soldering processes.
In order to improve the performance of PCBs, many people choose immersion tin process because it can prevent oxidation during processing and improve the quality of PCBs. However, as we all know, there are many different processes available on the market today, so how can we choose one that suits us best? Choose PCBTok to know what best suits you and your device.
Immersion Tin PCB by Type
Most widely used electronic materials which are widely used in communication, military and medical, measurement and control equipment field.
Our double-sided PCBs provide superior thermal and electrical performance, making them an excellent alternative to plastic or aluminum cases.
Multilayer Immersion Tin PCBs offer the lowest noise, highest throughput and lowest cost in high volume designs. These boards exhibit a very low propagation delay, which is practically the same as air.
Flexible PCB is manufactured by the process of soft electroplating, which is based on immersion tin bath and polyurethane resin as a solder resist. Can be bent up to 180 degrees.
High thermal conductivity, solder-resist, flexible conformal coating. Has thermal performance to support various high-end electronic devices with low thermal resistance and its dielectric strength is excellent.
Its high rigidity combined with its flexibility and light weight gives a unique benefit to OEMs who can now add the benefits of tin to their products without compromising on rigidity or weight

PCBTok’s Immersion Tin PCB Production Process
PCBTok’s immersion tin PCB production process begins with our experienced engineers working with you to determine the best design to meet your needs. Our engineers will create a layout and design that is optimized for performance, while keeping in mind the constraints of your product.
Once you approve the layout and design, we start production. We begin by preparing a substrate for the PCB. This can be done by drilling holes in the board, or cutting out portions of it.
Next, we coat the substrate with a layer of copper and apply solder paste to it. After that, we place a photoresist on top of that and expose it to UV light so that only parts of it are clear and can be etched away during chemical processing.
Finally, we etch away any unwanted copper using chemicals or lasers before applying an immersion tin solution to protect against oxidation or corrosion over time; this also gives us a shiny finish that makes our product stand out from others on store shelves!

Immersion Tin PCB – The Ultimate FAQ Guide
Immersion tin PCB is a common material for communication PCB boards. Its surface finish is not as strong as that of immersed silver, but it has advantages. Its tin layer protects the copper layer from oxidation and short-circuiting, thus extending the overall shelf life. In addition, it is RoHS compliant, making it environmentally friendly. It also uses less water and chemicals than other materials.
Compared to immersion silver PCBs, immersion tin PCBs are cheaper and easier to manufacture. In addition, it has a shorter shelf life than immersion silver. Intermetallic compound diffusion and oxidation resistance are the two main advantages of dip tin PCBs. It is also compatible with a wide range of applications. Backplanes and press-fit pins can be inserted using tin-impregnated PCBs.
Choosing a surface finish is essential for a successful tin-plated circuit board. There are several types of finishes, each with its own advantages and disadvantages. Immersion Gold(ENIG), immersion tin, and immersion silver PCBs are the three most common types of surface finishes. You can choose the best type of coating for your needs.
