Company Advantages
1. The design of A-TECH hasl pcb finish is finished with high quality. It gives consideration to the contrast and consistency of dimension and the contrast and consistency of direction that aims to achieve rich change in spatial organization. It is offered with low dielectric loss
2. Our customers praise that there is no color aberration on the product, and the natural wooden texture is clear and beautiful. With a solder mask, it enjoys a good electrical insulation property
3. The product features a long service life. It shows a prolonged service life when it is exposed to EMC, changeable temperatures, moisture, dust, and mechanical shock environments.
4. The product can withstand certain wear and tear. Its mechanical action will not easily lead to the loss of materials from the surface. It is widely used in different electronics industries, such as telecommunication and consumer electronics
5. The product has stable operating pressure. During the operation, the pump depletion phenomenon is eliminated to avoid dry friction or damage to sealing. It has increased power densities which guarantee its long service life


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.
