Abstract

The invention relates to package technology for electronic circuit, which comprises: first, preparing electronic component array or discrete circuit of combined circuit with electrical characteristics output by location frame; second, laying a metal sheath or nonmetal case to the discrete circuit; third, pouring epoxy resin inside shell to package; fourth, drying the resin, inverting the poured component to fix on large print board by screw and supporting hole; finally, fixing a plurality of discrete modules on substrate to form a circuit integer by interconnection with wire. This invention cuts device volume, improves reliability, and has some economical benefit.

Description

technical field [0001] The invention relates to a packaging process for electronic circuits, more specifically to a packaging process for arrays of electronic components or combined circuits, and belongs to the technical field of electronic packaging. Background technique [0002] For arrays or combined circuits of various electronic components, in order to consider confidentiality and easy installation and maintenance, the modules can be packaged in metal or non-metallic casings to improve the electromagnetic compatibility characteristics of products and improve the reliability of electronic components or combined circuits. Confidentiality and market competitiveness. [0003] For current electronic components, only in the case of confidentiality, a certain or a group of components is simply placed in a special metal or non-metal box, and the inside is filled with epoxy resin to encapsulate it. This is a relatively common and commonly used process method. [0004] However,...
