Description

Ceramic Connector Blocks / Special Functional Ceramics Parts

1. Description:

Another important requirement in microelectronic packaging is small line resistance, to prevent any undesired voltage drops. To satisfy this requirement, low firing temperature multilayer glass–ceramic (MGC) substrates with gold or silver–palladium wiring have been developed. The dielectric constants for these materials are 3.9–7.8, smaller than that for alumina. These substrates thus allow high pulse transmission speed. The electrical resistivity of the wiring metals used in low firing glass–ceramic substrates is lower than that of molybdenum or tungsten.
