Aviation, chemical, printed chip resistors, primary glass, green, 600 ℃ dielectric paste

electronic pasteIt is a paste like substance uniformly mixed with solid powder and organic solvent. As a high-tech electronic functional material that integrates metallurgy, chemical engineering, and electronic technology, it is regarded as a key material for component packaging, electrodes, and interconnects. It is mainly used in the manufacturing of integrated circuits, resistors, capacitors, conductor inks, solar cell electrodes, printing, and high-resolution conductorsConductive adhesiveSensitive components and other electronic components are widely used in various fields such as aviation, chemical industry, printing, construction, and military, and have an irreplaceable position in today's information age.

Electronic pastes can be mainly divided into:resistor pasteAt present, research on electronic pastes mainly focuses on conductive pastes to meet the high application needs of electronic products in the directions of high integration, lightweight, intelligence, and green with the development of electronic information technology. This includes dielectric pastes, insulation pastes, packaging pastes, and conductive pastes. The composition of conductive paste is mainly composed of three parts: conductive phase, bonding phase, and liquid carrier. After mixing, stirring, and three roll rolling, a uniform paste is formed, which is printed on glass or ceramic substrates through screen printing technology. The film layer with a thickness of several micrometers to tens of micrometers is made by solidification processes such as laser, high-temperature sintering, or drying.

(1）conductive adhesiveUsed for microelectronic assembly, including thin wires and printed circuits, electroplated substrates, metal layers of ceramic adhesives, metal chassis connections, bonding wires and sockets, bonding components and flat holes passing through printed circuits, bonding waveguide tuning, and hole repair.

(2) Conductive adhesive is used to replace spot welding where the welding temperature exceeds the tolerance of the oxide film formed during welding. As a substitute for tin lead solder, conductive adhesives are mainly used in telephone and mobile communication systems; Broadcasting, television, computer and other industries; Automotive industry; Medical equipment; Resolve electromagnetic compatibility (EMC) and other related issues.

(3) Another application of conductive adhesives is for bonding electrode sheets to magnetic crystals in ferroelectric devices. Conductive adhesives can replace welding flux and crystals that tend to deposit due to welding temperature. The bonding of battery terminals is another use of conductive adhesive when the welding temperature is unfavorable.

(4) Conductive adhesives can form joints with sufficient strength and can therefore be used as structural adhesives.
