Problems solved by technology

However, this electronic component has the following defects: first, because the heating and welding needs to adopt a reflow furnace, the process is complicated and time-consuming, which will seriously affect the productivity and increase the processing cost; The opportunity to dissolve air impurities in the place will reduce the conductive quality and welding strength of the welding place, which will lead to tin collapse when the solder ball is welded to the circuit board, resulting in the electronic components not being able to effectively conduct electricity with the circuit board

Abstract

This invention discloses a connection method for a electric conductor and a solder which is stuck on the conductor or an insulation body containing the conductor by adhesives, then to heat the solder to be melted to solder the conductor and the butt-joint electronic elements including the insulation body and several conductors and solders in the insulation body, adhesives are put between the tin sweat and conductor or the insulation body for fixing them.

Description

technical field [0001] The invention relates to a connection method of a conductor and solder and an electronic component using the connection method. Background technique [0002] At present, many electronic components, such as CPU socket connectors, board-to-board electrical connectors, etc., use BGA (ball grid array, ball grid array) to directly bond them to the circuit board by using surface bonding technology. . The electronic component includes an insulating body and a plurality of conductors and tin balls accommodated in the insulating body. The conductors and tin balls are welded together in advance. This electronic component is assembled as follows: first insert the conductor into the insulating body, then stick the tin ball to the bottom of the conductor, and then solder the tin ball to the conductor by heating. However, this electronic component has the following defects: first, because the heating and welding needs to adopt a reflow furnace, the process is comp...
