Product Information of Immersion Silver PCB
Application Scope
The PCB Assembly produced by A-TECH can be used in many fields.A-TECH always gives priority to customers and services. With a great focus on customers, we strive to meet their needs and provide optimal solutions.
Company Advantages
1. A-TECH carbon ink pcb is manufactured through a closely controlled chemical combination. The raw materials are processed at high temperatures to achieve great chemical properties such as anti-rust and anti-corrosion.
2. Since we have built the sophisticated QC system, the product quality from design to mass production is assured.
3. A-TECH CIRCUITS Co., Ltd. has a good market outlook.
4. A-TECH CIRCUITS Co., Ltd. has a creative and professional hasl pcb design team and skilled staff.


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.
