Silicon Nitride Board Material Introduction

First of all, the silicon nitride board material is introduced, and the strength of silicon nitride is very high. In particular, hot-pressed silicon nitride is one of the hard substances in the world, can withstand high temperatures, and the strength can be maintained to 1200 high temperatures. After being heated, it will not melt into a molten body and decompose to 1900. It has amazing refractory academic performance, can resist almost all inorganic acids and 30%, and is also a high-performance electrical insulation material-silicon nitride process technology. In the normal pressure sintering method (PLS), the pressure of the sintering nitrogen atmosphere is increased by utilizing the property that the decomposition temperature of Si3N4 is increased (usually N2 = 1atm pressure, decomposition starts from 1800 atm). 17003354

Introduction of some relevant knowledge about silicon nitride sheet

Silicon nitride sheet is the heat dissipation substrate for high-power devices and LED high-power packaging. It is based on the high thermal conductivity of silicon nitride sheet, which can reach more than 170 watts, which is more than 5 times that of alumina ceramic substrate and 100 times that of ordinary PCB, far exceeding the heat dissipation capacity of copper substrate, aluminum substrate and PCB.

What are the advantages of choosing silicon nitride sheet as a packaging material?

The silicon nitride plate mainly uses the high thermal conductivity of the material to conduct heat and realize the heat exchange with the external environment. For power semiconductor devices, the package substrate must meet the following requirements: 1. High thermal conductivity. Currently, power semiconductor devices are packaged using thermoelectric separation, and most of the heat generated by the device is transferred through the package substrate. The substrate with good thermal conductivity can protect the chip from thermal damage. 2. The thermal expansion coefficient of the packaging material and the chip material match. The power device chip itself can withstand high temperatures, and changes in current, environment, and working conditions will change its temperature. Since the chip is directly mounted on the package

Discussion on the composition of silicon nitride igniter

The relationship between the power supply voltage used by the silicon nitride igniter and the matching high voltage film is as follows. AC CDI igniter and back pressure AC igniter use capacity to save electricity "silicon instantaneous discharge principle, high voltage package output ultra-high voltage. AC pulsed high-voltage electricity using a magneto output (called a AC-CDI igniter) is used at the same time as the CDI high-voltage package suitable for pulsed high-voltage electricity.

What is the principle of silicon nitride igniter?

In fact, the silicon nitride igniter control principle can be very similar to the flint principle of a lighter. Connecting the plug is the handle of the gas stove. When we press the handle, the plug will touch the convex part of the hammer. When we turn the handle to the left, the plunger of the si3n4 igniter will move to the left together and hit the convex part of the hammer. As the angle of one rotation technique increases, the ignition hammer is separated from the insert, and the piezoelectric material element can be quickly hit under the action of the spring.
