2, Background information

With the advent of the integration of electronic components, electronic devices have posed higher demands on circuit miniaturization, high-density, multi-function, high reliability, high speed and large power. Co-fired multi-layer ceramic substrate meets all these requirements so it has been used in a wide range of applications in recent years. Co-fired multi-layer ceramic substrate can be divided into high temperature co-fired ceramic (HTCC) substrate and low temperature co-fired multi-layer ceramic (LTCC) substrate. Compared to LTCC, high temperature co-fired ceramics (HTCC) has higher mechanical strength, higher wiring density, better chemical stability, higher thermal dissipation coefficient and lower cost and is widely used in the heating and packing applications requiring higher thermal stability performance, less high temperature volatile gases and better sealing. High temperature co-fired ceramic heating element is a good alternate of alloy wire and PTC ceramic heating element and component.

5, Technical parameters

5.1 Appearance:

1. Smooth surface
2. Neat edge
3. Silver electrode
4. White ceramic body
5. Our "efficient Tape Casting ceramic substrates" technology prepares ultra-thin, ultra-smooth ceramic green body which ensures the smooth surface of the ceramic body. Precision hot press lamination ensures the neat edge. Electrode points are nickel plated and spot welded leads after firing, so the electrodes appear silver.

5.2 Dimension tolerance:

1. Length direction: ± 1.2mm
2. Width direction: ± 0.5mm
3. Thickness direction: ± 0.1.
4. After repeated firing experiments, our R & D personnel has collected the green body shrinkage data, and summed up the appropriate rate of contraction based on experimental results. Through careful control of the casting, punching and lamination process, we minimize the size differences between the green body and the firing product.
