Company Advantages
1. A-TECH carbon ink pcb is fabricated using optimum quality raw materials and pioneering technology. It is vacuum-sealed, which can greatly reduce the bulk of the overall cargo
2. Because of the tight, thick weave, its fabric can be somewhat water resistant and allergen-proof, yet will not be too hot. With a solder mask, it enjoys a good electrical insulation property
3. pcb surface finish is manufactured based on high-quality raw materials and special process. It has good flame resistance, acid and alkali resistance, and aging resistance, as well as excellent wear resistance and tear resistance.
4. Its quality is ensured for a better global competitiveness. The inner layer core of the product is chemically treated for improved adhesion of the copper surface
5. A quality assurance system has been established and improved to place the product's performance indicators at the forefront of the industry. Its working panel is coated with a photo-sensitive epoxy-based ink, which can ensure its insulation resistance


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.
