Indium foil indium tablets commonly used specifications:
Other sizes can be customized according to customer requirements, can process hole parts, shaped parts, if necessary, please contact us!
Advantages of indium foil/sheet products:
1. The quality of raw materials of the company is
the same as that of American Indium Corporation,
with higher content and less impurities.
2, the surface is oil-free and wax-free.
3, the surface layer is not oxidized.
4, the thickness uniformity is good.
Factors affecting the performance of indium foil indium sheet: 1, surface oil and wax, will block contact with the device, seriously affecting the performance of indium foil.
2, impurity elements, the content of two kinds of impurity elements have a great influence on the thermal conductivity of indium foil, and must be strictly controlled.
3. Surface oxidation, severely oxidized surfaces are essentially fatal to heat transfer, soldering and electrode use.
Application
The following analysis results are based on the company's long-term survey feedback on terminal research customers. Thanks to the cooperation and support of the following units: Institute of Optoelectronic Technology of Hal Ice University, Institute of Microsystems of Chinese Academy of Sciences, 11th, 27, 41, 46 of China Electronics Industry Group, etc. The production applications include: heat conduction, low temperature sealing, welding, electrodes, mercury absorption, etc.
Indium foil/sheet use: Indium foil is mainly used for low temperature vacuum sealing, high-end equipment cooling, nuclear industry neutron measurement and fuel cells. These aspects require that the indium foil surface be clean and free of oxidation.
