Immersion silver finish
Did you know?
Immersion silver plating (or IAg plating) is a surface plating process that creates a thin layer of silver over copper objects. It consists in dipping the object briefly into a solution containing silver ions. Immersion silver plating is used by the electronics industry in manufacture of printed circuit boards (PCBs), to protect copper conductors from oxidation and improve solderability. WitrynaImmersion silver is a type of surface finish used on PCB surfaces. PCB …

Witrynainclude electroless nickel/immersion gold, organic coatings, immersion tin, and immersion silver. According to industry estimates, the newest of the alternative circuit board finishes, immersion silver, is now used in 8% of the market.2 Chemical suppliers have offered immersion silver since the early 1990’s, however some board fabricators WitrynaImmersion Silver. Immersion Silver (IAg) is applied directly to the base metal of a PCB via chemical displacement. It’s a more affordable option than ENIG, and it is also RoHS-compliant. A typical thickness for Immersion Silver is 4-12u”. Due to the way copper and silver interact, they eventually diffuse into one another.
Witryna31 paź 2024 · Immersion Silver is a preferred surface finish for those concerned with solderability and being able to easily probe directly to the finish during ICT. During the soldering process, the silver layer dissolves into the solder joint, leaving a (6-12 µin) Tin/Lead/Silver alloy on the Copper, making very reliable solder joints for BGA …
