The main task of the final finish is to protect the copper pad from tarnishing or oxidation while simultaneously keeping the surface active for the assembly. Electroless nickel/immersion gold (ENIG) is a widely accepted finish in the market that provides a good solderability and capability for Al-wire bonding. A main function of the gold layer is to prevent the oxidation of the nickel layer.

Immersion tin is well accepted as a high-reliability final finish in the industry. Due to its excellent corrosion resistance, it exhibits major market shares, particularly in the automotive industry. During the soldering process, an intermetallic compound (IMC) is formed between copper and tin. One remaining concern in the industry is the potential impact of the IMC on the solderability of the final finish. In this article, typical failure modes in soldering immersion tin are described and correlated to potential root causes for the defects.

Regardless of the potential distraction of the international football match between England and Wales in the World Cup competition, an enthusiastic crowd of PCB fans gathered in Meriden UK for the Institute of Circuit Technology Christmas Seminar, an eagerly-awaited networking opportunity that included a face-to-face industry welcome event and an outstanding technical programme. Guest speakers highlighted new technology in selective solder nozzles, flexible circuits, industry cooperation, and a greener future by recycling PCBs.
