C8710M

Description

C8710M is an unfritted Ag conductor designed for thick print applications. In a single print and fire application, C8710M yields a thick, dense film that is free from listers, cracks, and other cosmetic defects. It exhibits excellent solderability and low resistivity. C8710M has good adhesion when printed over a base layer of C4740L or other silver based Heraeus conductors. It is not designed to be used without a base layer. C8710M is an excellent choice for low cost, high conductivity applications that require very thick conductor traces.
