Electroplating solder
Did you know?
The electrolyte should contain positive ions (cations) of the metal to be deposited. These cations are reduced at the cathode to the metal in the zero valence state. For example, the electrolyte for copper plating can be a solution of copper(II) sulphate, which dissociates into Cu cations and SO 4 anions. At the cathode, the Cu is reduced to metallic copper by gaining two electrons. WebTypical wafer level packaging involves a multitude of processes, including redistribution lines, copper pillars and solder bump formations for both Fan-in and Fan-out wafer level applications.

WebNov 15, 2024 · The contamination of plating solutions, such as the dissolution of the solder resist (SR) and side reaction products, impurities (Cu, Ni, and drag-in), can be a cause of black pad. The SR is used to prevent the unnecessary parts from attaching to the PCB, protect the PCB surface circuit from an external environment, and maintain the electrical ... WebHASL has board thickness up to 200 mils. Because the process is dependent on the board technology, plates may be slower during electric conductions. Also, it is challenging to maintain hole-size tolerance along the plated edges. ENIG’s plate has a typical thickness of 5-15 in minimum gold, making it easy to solder.
