| PCB fabric-ations are, at present, limited within varieties of
reinforced plastic laminates. In special cases, ceramic substrates of
alumina aud beryllia are also used. Glass-bonded mica also holds a
good potentiality as a PCB material, especially in view of a unique
combination of mechanical, thermal and electrical desirability and
also for low cost of production. An attempt has been made to prepare
PCB with glass-bonded material developed at the Institute. |
