Product Information of Immersion Silver PCB
Company Advantages
1. Each design of A-TECH enig pcb finish is evaluated using carefully calibrated simulations followed by meticulous testing and fine-tuning to get the ride experience optimal and safety-assured. It can be manufactured with a customized thickness
2. If you have questions about hasl pcb , feel free to contact our customer service team. A smooth part is added on its PTH line to reduce the roughness of through hole
3. Our team adheres to a high standard of quality inspection policy to ensure its quality. Thanks to the up-to-date vacuum DES line, it is manufactured with fine traces and high density


Immersion Silver, it’s also known as Immersion Ag, it’s produced by the selective displacement of the copper atoms by silver atoms on the exposed copper surface. As an improvement on HASL with more flat surface, the cost of Immersion Ag is more expensive than HASL but less expensive than Immersion Gold.

Immersion Ag is a RoHS compliant finish, and it’s compatible with surface mount, BGA and through hole components. The typical thickness of Imm Ag is 0.1-0.3um and the shelf life is 6-12 months.



The advantages of Immersion Silver

● Absolutely flat
● Good for fine pitch and SMD
● Good for press fit connector’s capability
● Excellent solderability
● Multiple heat cycles during assembly process
● It’s reworkable



The disadvantages of Immersion Silver

● Very sensitive to handling / tarnishing / cosmetic concerns – gloves must be used
● Short operating window between assembly stages
● Not recommended to use peelable masks
● Special packaging required – if packaged opened and not all boards used, it must be resealed quickly
● Reduced supply chain options to support this surface finish



A-TECH offers the surface finish of immersion silver, since this finish is much more sensitive in manufacturing and it’s more susceptible to temperature and humidity than other finishes, we use special operation standards and higher level of packing standards to ensure excellent appearance of immersion Ag.
