Company Advantages
1. carbon ink pcb is applied to ensuring carbon pcb to be of great durability and stability. It is lead-free and environmental-friendly and has passed SGS test
2. LED doesn't fail abruptly and relatively has a long useful life. This reduces the cost in terms of maintenance and reduces your headache for periodical replacements. It stands out for its impact endurance performance
3. The product has a fine tenacity. It can withstand the influence of exterior force such as incision, peening, bending, and pulling. It has low water absorptivity in the damp environment
4. The product features excellent color fastness. It is good at retaining color in the condition of washing, light, sublimation, and rubbing. It can reduce the electrical signal loss and provides the highest efficiency


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.
