In the medical field, the surface treatment technology of printed circuit boards (PCBs) is very important. Choosing the right surface treatment method can not only improve the reliability and performance of the equipment, but also extend its service life. First, let’s explore several common surface treatment methods. 1. **HASL (Hot Air Leveling)**: HASL is a technology that covers the pad with molten tin-lead alloy. It is cheap and has good soldering performance, but it may cause uneven surface and is not very friendly to high-density PCBs. 2. **Immersion silver**: The immersion silver process produces a uniform layer of silver, which can improve conductivity and solderability. The disadvantage is that it is easy to oxidize and requires special storage. 3. Immersion Gold: Immersion Gold technology provides excellent flatness and anti-oxidation performance, which is very suitable for complex and high-density PCBs. However, its cost is relatively high. 4. **OSP (Organic Solder Protection Film)**: OSP is an environmentally friendly technology that uses organic materials to form a protective film on the surface of copper solder joints. It is simple to operate and low in cost. However, its heat resistance and protection are weak. Comparing the advantages and disadvantages of these technologies will help to select the optimal surface treatment solution. The specific choice should be determined based on the actual application scenario and budget. In the future, as technology advances, we can expect new surface treatment technologies that are more efficient and environmentally friendly to emerge, injecting new vitality into the medical PCB industry. ⚙️🌟 Through this article, we hope to provide readers with valuable information so that everyone can be more informed and confident when choosing medical PCB surface treatment technology.
