Product Comparison
Compared with products in the same category, PCB prototype we produce is equipped with the following advantages.
Application Scope
Multiple in function and wide in application, Multilayer PCB can be used in many industries and fields.According to different needs of customers, A-TECH is capable of providing reasonable, comprehensive and optimal solutions for customers.
Company Advantages
1. A-TECH tin plating pcb is made of materials that are all meet the food grade standard. The raw materials sourced are BPA-free and will not release harmful substances under high temperature.
2. immersion tin pcb enhance the tin plating pcb efficiency with such properties as silver coating pcb .
3. A-TECH PCB has set up its own global sales channel for immersion tin pcb .
4. Our immersion tin pcb is popular in many overseas markets.


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.




Company Features
