Industry development background – circuit board development
-
Circuit board (PCB)
It is the basic material of electronic information industry (mechanical support, high density interconnection and heat dissipation of buried copper block, etc.).
Disadvantages: resin substrate (insufficient heat dissipation).
-
Metal circuit board (PCB)
To a certain extent, the cooling requirements are solved, but the cooling effect is far from expected. With the increase of chip power and package integration, thermal conductivity/heat resistance of circuit board becomes the bottleneck of technology development.
Disadvantages: Metal substrate (thermoelectric non-separation)
-
Ceramic substrates
Meet the application requirements of new technologies. Application: From LED lighting –UV light —- Power devices — High temperature devices (Aviation/aerospace) — 3D packaging (high power density).
Advantages: excellent thermal conductivity/heat resistance/insulation performance, small thermal expansion coefficient, corrosion resistance, etc.
