Abstract

The invention discloses a self-adaptive parallel sealing and welding method for microelectronic packaging in a high vacuum state, and solves the problem of how to complete high-quality parallel seal welding of a cover plate and a tube shell of a thin-shell device at low cost in a vacuum environment so as to improve the sealing and welding yield. A floating parallel welding wheel support is arranged, two parallel welding wheels on the support are pressed on parallel welding seams between the cover plate and the tube shell in a floating mode, weights are arranged at the top end of the parallel welding wheel support, and the welding pressure of the parallel welding wheels on the welding seams is adjusted by increasing or reducing the number of the weights, so that the adjustment of the self-adaptive welding pressure in the welding process is realized; a shoulder-pole-shaped semi-square-shaped jacking frame body is arranged between the left parallel welding wheel support and the right parallel welding wheel support, the floating parallel welding wheel supports are lifted and lowered through jacking connection of eccentric wheels to the semi-square-shaped jacking frame body, and conversion between a welding state and a to-be-welded state of the two parallel welding wheels is completed. and the sealing and welding quality of the packaging assembly is greatly improved.

Description

technical field [0001] The invention relates to a microelectronic packaging device, in particular to a mechanism and a welding method for parallel welding a thin-shell device cover plate and a tube shell in a microelectronic packaging assembly in a high-vacuum chamber. Background technique [0002] Microelectronic packaging and assembly (MEMS devices), that is, using film technology and micro-processing technology to arrange, paste, fix and connect chips and other elements on the frame or substrate, lead out the connection terminals, and potting and fixing them through plastic insulating media. Then, according to the electrical schematic diagram or logic diagram, using microelectronic technology and high-density assembly technology, microelectronic devices and micro-miniature components are assembled into applicable and producible electronic components, components or a technical process of a system; currently, vacuum packaging The equipment is changing from a single machine ...
