High Thermal Conductivity Ceramic PCB High stability For Medical Equipment
♦ What is Ceramic PCB?
Ceramic substrate refers to a special process board in which copper foil is directly bonded to the surface (single or double sides) of alumina (Al2O3) or aluminum nitride (AlN) ceramic substrate at high temperature. The ultra-thin composite substrate has excellent electrical insulation performance, high thermal conductivity, excellent soft solderability and high adhesion strength. It can also be etched with various patterns like PCB boards, and has a large current carrying capacity.
♦ Features of Ceramic PCB
Physical properties: strong mechanical stress, stable shape, high strength, high thermal conductivity and high insulation; strong bonding force, good corrosion resistance.
Thermal properties: good thermal cycle performance, up to 50,000 cycles, high reliability; thermal expansion coefficient is close to silicon chips, which can simplify the production process of power modules; wide operating temperature range, -55℃~850℃.
Other features: various graphics can be etched like PCB boards (or IMS substrates), pollution-free and harmless; under the same current carrying capacity, the line width of 0.3mm thick copper foil is only 10% of that of ordinary printed circuit boards; ultra-thin (0.25mm) ceramic substrates can replace BeO, without environmental toxicity issues.
