Company Advantages
1. A-TECH hasl pcb finish complies with the essential international electrical safety requirements. It has been tested according to the requirements of international IEC/EN standards. The product is certified under UL(E357001) and RoHS
2. The surface of the product is treated by advanced insulation materials to prevent electrical conduction. Obviously, its non-conductive surface is safe for users even they touch on it. The product has the performance of great stability
3. It is not easy to get the ball. The product will be antistatic and soft to reduce its coefficient of friction. It is lead-free and environmental-friendly and has passed SGS test
4. The product is safe to use. Those parts that are easily tossed out are equipped with safety devices such as a shield or protective screening. Its solderable surface is protected from the oxidation


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.
