C2140

Description

C2140 is a Pd/Ag composition designed for applications where more leach resistance is required. The C2140 conductor is suitable for a wide variety of applications such as automotive electronics, power hybrids and commercial circuits where more stringent requirements exist. It exhibits excellent solderability, aged adhesion and is aluminum wire bondable.
