A-TECH immersion hasl pcb free delivery for wholesale

Company Advantages
1. A-TECH silver coating pcb is carefully crafted. Factors such as the dimensions of the assembly and the machine elements, materials, and method of production are clearly specified before its manufacture. It is offered with low dielectric loss
2. A-TECH CIRCUITS Co., Ltd. promotes a positive brand image with its superior customer service. With a compact design, it is space-saving
3. This product feels soft and has many other amazing qualities such as hypoallergenic material and moisture wicking & anti-microbial fabric. The inner layer core of the product is chemically treated for improved adhesion of the copper surface
4. The shape and form of the product can emphasize certain parts of the body while downplaying other less desirable parts. Its working panel is coated with a photo-sensitive epoxy-based ink, which can ensure its insulation resistance
5. The product is dimensionally stable. It can be kept in its original size and shape, washed by hand, or on the machine, or dry cleaned. It is vacuum-sealed, which can greatly reduce the bulk of the overall cargo

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.
