Enterprise Strength
  • continuously improves service capability in practice. We are dedicated to providing customers with more favorable, more efficient, more convenient and more reassuring services.
Application Scope
A-TECH's PCB prototype is widely used in the industry.According to different needs of customers, A-TECH is capable of providing reasonable, comprehensive and optimal solutions for customers.
Company Advantages
1. A-TECH lead free hasl pcb is of scientific design. Its shape is determined by the shape and characteristics of the commodity in order to enhance the expressive force.
2. This product can be easily transported by ship, truck or rail. It already conforms to standard shipping dimensions before leaving the factory.
3. With a breathable and high-functioning fabric, the product is an ideal solution for warm sleep in particular due to the superior level of thermal control and moisture wicking that it provides.
4. All defected immersion gold pcb will be picked up and not allowed to deliver to our customers.
5. The adoption of lead free hasl pcb method can cause tin plating pcb and satisfy production requirements.


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.
