Company Advantages
1. A great variety of models are designed by our professional designers to make hasl pcb more attractive. It totally conforms to the UL Flame Rating of 94V-0
2. It could be the primary material for a fashionable pair of shoes, whether they're sneakers, ballet flats or wedge sandals. - Said one of our customers. Being laminated by advanced vacuum lamination equipment, it has a uniform dielectric thickness after lamination
3. The product has enough robustness. It is made of superior and strong materials that contribute to a robust, hard-wearing structure. It is lead-free and environmental-friendly and has passed SGS test
4. The product features a fine cushioning effect. Made of flexible and soft materials, it can absorb the impact posed on the feet. The product can be resistant to corrosion


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.
