WebDec 10, 2024 · Whiskers are electrically conductive and mechanically strong and grow faster towards high voltage gradients. Other factors that affect the growth rate of whiskers are humidity and operating temperature, solder composition, contamination, etc. [14,15]. The next mechanism that can lead to the failure of an electric device is the formation of voids. WebOur immersion tin processes represent the pinnacle of trusted reliability for tin metal final finishes in the automotive electronics ... to diffusion of copper into the tin while also creating a unique low-stress grain structure which greatly reduces whisker formation. The pre-dip makes the PCB highly resistant to oxidation and copper ...

WebAn immersion tin plating solution is a re-usable solution that deposits tin onto copper traces on a circuit board. Professionals call this process immersion tin plating and reserve the term electroless for something else. The solution can plate 1.0 to 1.5 microns, depending on the size of the part to undergo plating.
