Electronic Paste silver metal powder, palladium metal powder, gold metal powder
Electronic paste
Electronic suspensions according to the price level of the conductive phase can be divided into precious metals and base metals electronic pastes electronic slurry.
1. precious metals electronic pastes: Silver is the best electrical properties of metallic materials, usually in silver to add only trace metals, a relatively new technology is added to a slurry of metal compounds to improve the dispersion of the slurry, with the the rapid development of China's electronics industry, Ag powder material will be widely used in various fields of electronic technology, chemicals, pharmaceuticals and the like.
2.Pd conductive paste: metal palladium also has good electrical conductivity, but within a pure palladium electrode paste used only for high-temperature sintering of multilayer ceramic capacitors and multilayer ceramic capacitors as to the direction of the development of the cryogenic medium, The amount of pure palladium conductive paste will continue to decrease.
3.Au conductive paste: Has developed various types of gold conductor paste mainly divided into three types: with a glass, containing only non-oxide glass, while gold conductor paste containing glass and oxides. No glass gold conductor paste is widely used in bonding aspect of the multilayer wiring conductor and high-power transistor chip and the lead frame.
4.Ag-Pd conductive paste: silver palladium conductive paste, the rate of diffusion of silver ions is only a fraction of silver, and even a number of low-level, Ag-Pd Pd content basis having conductive paste requirements may be, from 5% to 95% range, which 70Ag-30Pd conductive paste is commonly used in MLC electrode paste.
5.Au-Pd conductor system not only high adhesion strength. Weldability good, and can co-firing with Ag-Pd-based resistance paste, forming a low-noise exposure. Au-Pd conductor does not exist diffusion line, so often used for high reliability and multi-layer wiring applications.
