The benefits of this surface finish outweighs its costs. Due to this, immersion silver has become popular in the PCB industry. It is now a preferred choice among Flex rigid PCB manufacturers. Immersion silver has several advantages which include:
Excellent flatness
Immersion silver has a very flat surface. This is very beneficial for SMD assembly. Also, it has exceptional surface planarity that makes it easy for manufacturers to work on. With this type of surface finish you can install surface components like Ball Grid Array (BGA).
RoHS Compliant
This is of the benefits of this surface finish. Immersion silver is environmentally friendly; hence, it complies with industry standards.
Good solderability
Immersion silver has great solderability after several thermal excursions. Also, the surface allows solder to spread evenly. Therefore, you can efficiently solder components.
Excellent conductivity
Immersion silver surface finish has great conductivity which makes it ideal for use in devices with high-speed signal design.
Low cost
Due to its low cost, immersion silver is a preferred surface finish among PCB manufacturers. Immersion silver is ideal for PCBs fabricated with low budgets.
