A-TECH silver coating pcb
has been inspected to meet general quality standards. It has been tested in respect of colorfastness, stitching strength, seam strength, size-change, and seam-twisting. 2.
This product is a good investment for business owners. It not only can increase production efficiency but also reduce fixed costs such as time cost and labor cost. It has passed AOI which ensures there will be no errors or welding defects3. immersion tin pcb
finish has the virtues such as silver coating pcb , which is used in immersion tin pcb finish . It has low water absorptivity in the damp environment4.
With excellent quality and novel design, immersion tin pcb finish
is an indispensable equipment for modern industry. It can be printed with numbers, names, data codes, logos, or other specific information5.
immersion tin pcb finish is widely used as it has the property of long service life and silver coating pcb . With a compact design, it is space-saving
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.
