LPA92-59

Description

LPA92-59 is a screen printable gold conductor paste, designed to metallize punched or laser drilled through-holes in alumina substrates.

Key Features

LPA92-59 contains a glass-filler, for good adhesion on to the inside wall of holes (through-holes) The viscosity has also been adjusted, for good vacuum through-hole printing It also works well as via-fills in multilayer dielectric, for interconnecting conductor layers
