Company Advantages
1. A-TECH pcb mask has been tested according to the requirements of international IEC/EN standards. It has been tested in terms of low-frequency phenomena (flicker and harmonics) and high-frequency conductive currents, voltage, and power.
2. This product will be an ideal choice for people who would like to improve their foot health thanks to its proper fit and desired comfort. Its solderable surface is protected from the oxidation
3. The product is characterized by top quality, corroborating efficiency with affordability. It is definitely a necessary addition to the office accessories. The inner layer core of the product is chemically treated for improved adhesion of the copper surface


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.
