Electromagnetic pulse welding equipment for electronic packaging and welding method thereof

Abstract

The invention discloses electromagnetic pulse welding equipment for electronic packaging and a welding method of the electromagnetic pulse welding equipment, welding spots on the back of a PCB (printed circuit board) are welded at a time through the electromagnetic pulse welding equipment, hot melting welding in an electronic packaging welding technology is replaced, the PCB does not generate a large amount of heat in the electromagnetic pulse welding process, the PCB does not deform, and the welding quality of the PCB is improved. The welding quality of PCB welding spots is improved, in the actual machine welding process, the PCBs only need to be placed in the mounting grooves to be fixed, the PCBs are automatically conveyed to the welding station and the taking station through the conveying belt, the PCBs at the welding station are automatically welded through the electromagnetic pulse welding device, the welding efficiency is greatly improved, and the welding efficiency is improved. And the welded PCBs on the taking station are unloaded and transferred by the taking device, so that the whole welding process is quick and convenient, manpower is saved, and the welding working efficiency is high.

Description

technical field [0001] The present invention relates to the technical field of electromagnetic pulse welding, in particular to an electromagnetic pulse welding device used for electronic packaging and a welding method thereof. Background technique [0002] Electronic packaging refers to the casing used to install semiconductor integrated circuit chips. It not only plays the role of placing, fixing, sealing, protecting the chip and enhancing thermal conductivity, but also a bridge to communicate the internal world of the chip and the external circuit - the contacts on the chip pass through Soldered to the pins of the package, which in turn establish connections to other devices through wires on the printed circuit board. [0003] In the existing electronic packaging welding technology, because there are many welding parts involved, and most of them are carried out by hot-melt welding, such as solder connection, and hot-melt welding is easy to accumulate a large amount of ther...
