Company Advantages
1. The steel construction of A-TECH osp coating pcb is designed and engineered by our in-house professional engineers. The production of this steel- hot dipped galvanized- is also undertaken in-house by our experienced team. It can reduce the electrical signal loss and provides the highest efficiency
2. The product has a low working temperature, which keeps the area, where they are installed, cool. Users who get annoyed by the heat produced by a conventional bulb can enjoy this huge benefits of this product. It is characterized by high thermal conductivity and good heat dissipation
3. The product is highly hygienic. The hygienic design will collect minimal stains or gather germs, which effectively minimizes the risk of cross-contamination. A smooth part is added on its PTH line to reduce the roughness of through hole
4. The product is not susceptible to fade. It has been processed under high temperature which enables the color to stick firmly. It totally conforms to the UL Flame Rating of 94V-0


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.
