I、Industry background:

Ceramic Copper clad plate, also known as DBC (Direct Bond Copper) ceramic substrate, is an electronic base material that sintering copper foil directly on the surface of a ceramic. This material has many remarkable characteristics, such as good insulation properties, excellent heat dissipation properties, low thermal resistance coefficient, matched thermal expansion coefficient, good mechanical properties and weldability. Ceramic copper clad plates are mainly used in power electronics module technology as a carrier for various chips (such as IGBT chips, Diode chips, resistors, SiC chips, etc.). Its function is similar to PCB board, and it can complete the connection of the electrode or connection surface of the chip.

The application fields of ceramic copper clad plate are very wide, including high-power power electronic circuits, semiconductor coolers, electronic heaters, power control circuits, high-frequency switching power supplies, solid state relays, automotive electronics, aerospace and military electronic components, solar panel components, etc.

II、Application requirements:

1, multi-channel AC withstand voltage test system. N channel parallel test function (can be used to test N products at the same time, can also test a product or a few products alone; Each product has A, B, C a total of 3 points), can choose to open or close one or more test channels according to actual needs, can be automatic mode test, can also be manual mode test, the two states of the contact can be switched, the voltage value can also be set arbitrarily.

2, channel switching, each channel can be realized, A→B+C circuit voltage test, at this time point A high voltage, point B, C cognate low voltage; Then A+B→C circuit voltage test, at this time point A, B homologous high pressure, point C low pressure.

3, each channel can be tested independently, avoiding series is the core function, is the basis for the parallel test can be carried out.

III、Solution:

Ruijie intelligent research and development of ceramic copper-clad plate pressure test system, is to test the ceramic copper-clad plate pressure performance development.
