Common PCB is generally made by holding copper foil and substrate, and the substrate material is for the most part glass fiber (FR-4), phenolic tar (fr-3) and different materials, and the cement is typically phenolic, epoxy, etc. During the time spent PCB making, because of warm pressure, substance factors, ill-advised creation innovation and different reasons, or in the plan cycle, because of the unevenness of copper laying on the two sides, it is not difficult to cause various levels of warpage of PCB.
The other hybrid integrated circuit substrate-clay substrate is generally utilized in high power
electronic modules, aviation, military gadgets and different items as a result
of its intensity dissemination, current conveying limit, protection, warm
development coefficient, etc.
Ceramic
circuit board is comprised of copper
foil and ceramic substrate by holding in high temperature climate. The holding
force major areas of strength for are, copper foil won't tumble off, the
dependability is high, and the exhibition is steady in high temperature and
dampness climate.

Benefits and impediments of ceramic PCB
Advantage
•The current conveying limit is enormous; 100A current goes
through 1mm 0. 3mm copper body consistently, the temperature increase is around
17 ℃; 100A current goes through 2mm 0. 3mm copper body
consistently, the temperature increase is somewhere around 5 ℃;
•Better intensity dispersal execution, low warm development
coefficient, stable shape, difficult to twist.
•Great protection, high voltage obstruction, to guarantee
individual security and hardware.
•Solid restricting power, utilizing holding innovation,
copper foil won't tumble off.
•High dependability, stable execution in high temperature and
dampness climate
