How to correctly choose the surface finishing of printed circuit boards? Whilst previously it was just enough to protect the board against corrosion and the base for all adjustments was plain copper, customers nowadays are able to select from a wide selection of various options. There are ever increasing demands on a higher frequency, extended lifespan and generally better resistance of materials. New technologies also enable boards designers a higher thickness of joints and smaller distances between individual components. In Gatema, at this time only, six different options of surface finishing are being offered. Unleaded and leaded HAL, immersion silver, immersion gold, chemical tin or galvanic nickel and gold.
