Background technology
At present, metal-glass sealing is widely used in the aspects such as electron tube, laser, infrared device and electric light source.According to the difference feature of the coefficient of expansion CTE of metal and glass, metal-glass sealing is divided into to two kinds of matched seal and unmatched sealings.Matched seal refers to that metal and glass have the close coefficient of expansion, constriction coefficient.Through the oxide of the cut down material surface of oxidation processes and the oxide in glass, at high temperature molten reaction forms seal mutually.And unmatched sealing is to utilize the characteristic of the compression strength of glass much larger than tensile strength, seal, sealing materials is carried out to non-matching selection.The coefficient of expansion of external metallization should be much larger than the coefficient of expansion of intermediate glass, and the coefficient of expansion of intermediate glass and the coefficient of expansion of interior metal adopt match selection, i.e. the outer gold of a > > selection principle of gold in glass >=a in a.This causes in the sealing-in process, with the reduction of temperature, especially in annealing temperature, is down to the room temperature stage, and the metal material that coefficient of linear expansion is larger produces certain compression to glass, make glass in contraction process in a kind of compressive state.
Therefore, non-matching metal-glass sealing shell, in the processes such as its outer lead is shelved at sintering, sealing, chip, electrical testing, environmental test, glass is vulnerable to the pulling force effect, causes the strength decreased between lead-in wire and glass insulator, affects circuit reliability.The outer lead of non-matching metal-glass sealing shell generally adopts the 4J50 alloy material or adopts 4J50 copper core composite material, and the lead wire tensile strength of this structural housing is low, easy loose or dislocation in the environmental test process.Unpredictable element in assembling, test and use procedure, also easily cause lead-in wire loosening, and circuit is scrapped, and can't meet consumers' demand.
