As a kind of power generation device that converts chemical energy in hydrogen and oxidant into electricity, the gas tightness of fuel cell stack is very important. This is the test of VET for the ...
A fuel cell system uses the chemical energy of hydrogen or other fuels to cleanly and efficiently produce electricity. If hydrogen is the fuel, the only products are electricity, water, and heat. F...
SiC has excellent physical and chemical properties, such as high melting point, high hardness, corrosion resistance and oxidation resistance. Especially in the range of 1800-2000 ℃, SiC has good ab...
Advantages of graphite electrode
(1) With the increasing complexity of die geometry and the diversification of product application, the discharge accuracy of spark machine is required to be higher...
With the gradual mass production of conductive SiC substrates, higher requirements are put forward for the stability and repeatability of the process. In particular, the control of defects, the sma...
Fan out wafer level packaging (FOWLP) is a cost-effective method in the semiconductor industry. But the typical side effects of this process are warping and chip offset. Despite the continuous impr...
