金屬化陶瓷–用于電子元件和線路的錫焊

Metalized Ceramics for Soldering of Electronic Elements and Circuits

Alumina ceramic substrate offers excellent high frequency characteristics and high temperature-withstanding, corrosion -resistant, non-deformation, electrical insulation, and vaccum tight. Ceramic surface after metalization can be connected to metals by brazing. Further more, after gold-plating or tin-plating, it can be mounted and soldered on PCB. It has been widely used in vacuum electronic components, conductor base, resistor base, I.C. substraste, etc.
