DBC (Direct Bonded Copper)
The direct copper coating technology uses copper oxygen-containing eutectic liquid to directly bond copper to ceramics. The basic principle is to introduce an appropriate amount of oxygen between copper and ceramic before or during the bonding process, at 1065 ° C ~ 1083 In the range of °C, copper and oxygen form a Cu-O eutectic liquid, and the DBC technology uses the eutectic liquid to chemically react with the ceramic substrate to form a CuAlO2 or CuAl2O4 phase, and on the other hand, infiltrate the copper foil to realize the combination of the ceramic substrate and the copper plate. The thermal expansion coefficient of the ceramic substrate is close to that of the silicon chip, which can save the transition layer Mo piece, save labor, material and reduce cost;
◆Reduce the solder layer, reduce the thermal resistance, reduce the void, and improve the yield;
◆ The line width of 0.3mm thick copper foil is only 10% of ordinary printed circuit board under the same current carrying capacity;
◆ Excellent thermal conductivity, making the chip package very compact, which greatly increases the power density and improves the reliability of the system and device;
The role of ceramic substrate ceramic substrate according to the field of ceramic substrate application, is divided into HIC (hybrid integrated circuit) ceramic substrate, focusing potentiometer ceramic substrate, laser heating fixing ceramic substrate, chip resistor substrate, Network resistor substrate, etc.; according to different processing methods, ceramic substrates are divided into two types: molded tablets and laser scribe films. The ceramic substrate in the chip resistor substrate is a part of the chip resistor. The upper layer of the substrate is coated with different semiconductor materials, and then copper is plated on both ends for soldering. The biggest advantage of the whole resistor is that the volume can be made very well. small.
