Vacuum brazed Ceramic Copper Clad Laminates (CCL) are high-performance composite components widely used in power electronics, semiconductor equipment, electric vehicles (EVs), renewable energy systems, and high-power industrial applications. By combining the excellent electrical insulation of advanced ceramics with the superior thermal and electrical conductivity of copper, these assemblies provide outstanding heat dissipation and long-term reliability.
The vacuum brazing process is carried out in a high-vacuum brazing furnace using a specially selected active brazing alloy. The oxygen-free environment prevents oxidation and contamination while ensuring excellent bonding between the ceramic substrate and copper layers. This produces clean, high-strength metallurgical joints with excellent thermal conductivity, dimensional accuracy, and mechanical stability.
Compared with conventional joining methods, vacuum brazing delivers flux-free, void-free, and highly reliable joints that can withstand repeated thermal cycling and demanding operating conditions. The process also minimizes residual stress and enhances the durability of the finished product, making it suitable for high-performance electronic applications.
Vacuum-brazed Ceramic Copper Clad Laminates are widely used in IGBT modules, power semiconductor packages, EV power converters, high-power LED systems, industrial inverters, and electronic cooling solutions where efficient thermal management, electrical insulation, and long-term reliability are essential.
