Unlike immersion silver it is not vulnerable to tarnishing and does not need special storage. The reaction is fast approximately 1-2 minutes and does not require the relatively high temperatures of ENIG. ENIG Per IPC-4552. -> Low cost. Typically no-clean and low activity solder paste meets these requirements. Other polishes reverse the original chemical reaction, turning the silver sulfide back into normal, shiny silver. Calculating KW Capacity In general, KW capacity will be determined by one of two fac-tors: the heat required to bring the process up to temperature, and the heat required to maintain the process at operating temperature.
