4. The material and pin design should selected to
ensure that the strength the connection does not deteriorate substantially
over time, leading increase the contact resistance. Brass (copper/zinc),
bronze (copper/tin) copper beryllium are used, depending the size and
function the part.3 PCBs
PCBs should used accordance with IEC 326-3, IEC 326-5 and IEC
326-6.
The general requirements and testing methods are specified DIN EN
