Witryna25 lip 2024 · Confirmation of deposition reaction: In order to determine the oxidation reaction of “DIG R”, which is the reducing agent of Direct Immersion Gold, the rest potential was measured using a gold electrode and a copper electrode. The standard electrode was Ag/AgCl, and the working electrode was copper and gold plate. … WitrynaImmersion Ag Immersion Sn ENEPIG ENIG With the market price for gold at 20-year highs, ENIG is one of the most expensive surface finishes to apply. The gold deposit, even with limited thickness, becomes 70-80% of the cost to deposit ENIG. Chart 1 shows an approximation of process costs for several of the commercially available HASL …

Witryna1 lip 2010 · The solder joint microstructures of immersion Ag with Sn-xZn (x = 0 wt.%, 1 wt.%, 5 wt.%, and 9 wt.%) solders were analyzed and correlated with their drop impact reliability. Addition of 1 wt.% Zn to Sn did not change the interface microstructure and was only marginally effective. In comparison, the addition of 5 wt.% or 9 wt.% Zn … WitrynaImmersion Silver . This is a surface finish whose benefits far outweight its costs. It gained widespread popularity since the RoHS and WEEE directive took effect, and can be a good alternative to ENIG for fine pitch and flat pack coating. It's a stable finish with a moderate shelf-life (roughly 12 months) and relatively simple process control. ... WitrynaYour Leading Immersion Silver PCB Supplier in China.
