A method of manufacturing a solderable mixed metal package shell

Abstract

The invention discloses a manufacturing method of a weldable mixed metal packaging shell. The weldable mixed metal packaging shell comprises guide posts, and rigid jacks and flattened leads of which the internal and external end surfaces of the contact members can be bonded or welded, wherein the guide posts, the rigid jacks and the flattened leads are arranged on a base. The weldable mixed metal packaging shell is characterized in that the rigid jacks and the flattened leads are sleeved by glass insulators and then fixed by a graphite mould through three times of sintering so that insulating sealing of the contact members and the base can be realized. The graphite mould is composed of a graphite mould base and internal and external positioning moulds. Sintering temperature is 900-1000 DEG C, and time is 2-5h. Compared with the manufacturing method of the weldable mixed metal packaging shell in the prior art, manufacturing precision is high, airtightness is great, the insulation and voltage resistance value is high, the leads and the rigid jacks can be used for gold wire bonding, quick plugging is supported and the leads are not damaged after multiple times of plugging, direct connection with flexible pins can be realized, and thus the requirements for quick plugging with the flexible pins and weldability of the shell can be especially met.

Description

technical field [0001] The invention relates to the technical field of electrical connector packaging shells, in particular to a method for manufacturing a weldable mixed metal packaging shell for quick plugging and unplugging. Background technique [0002] At present, the form of the metal package shell is relatively fixed, mainly in the form of UP, UPP, FP, FPP, and PP. The contacts are also mainly made of leads. The outer leads are inserted into the printed board or welded and bonded for signal transmission and housing fixing. The lead wire and the chip are soldered or bonded with gold wire, which does not support quick plugging and unplugging, and it is easy to cause damage to the lead wire to varying degrees after repeated plugging and unplugging. [0003] In the prior art, the shell is usually fixed by screws. Due to the limitation of the shell shape and coating, it cannot meet the requirements of quick plug-in and pull-out of the flexible pin and the weldability of th...

[0002] At present, the form of the metal package shell is relatively fixed, mainly in the form of UP, UPP, FP, FPP, and PP. The contacts are also mainly made of leads. The outer leads are inserted into the printed board or welded and bonded for signal transmission and housing fixing. Leads are soldered to the chip or bonded with gold wires, which do not support fast plugging and unplugging and may cause varying degrees of damage to the leads after multiple plugging and unplugging

[0003] In the prior art, the shell is usually fixed by screws. Due to the limitation of the shell shape and coating, it cannot meet the requirements of quick plug-in and pull-out of the flexible pin and the weldability of the shell. The insulation and sealing performance of the contact piece and the base is poor, and the insulation Low withstand voltage
