Abstract

The invention discloses a method for the assembly and the reflow soldering of a PCB and an FPC and a special positioning fixture thereof, which mainly solve the problems of inaccurate positioning, low efficiency of welding efficiency, difficulty for ensuring product quality and the like of manual assembly in the processes of assembling and soldering the PCB and the FPC. The method comprises the following steps: firstly, supporting, positioning and fixing the PCB by using a magnetic carrier board; secondly, carrying the FPC; next, preliminarily positioning the PCB and the FPC with a bonding agent; thirdly, printing a solder paster on a solder pad at the junction of the FPC and the PCB; and finally, pressing a magnetic cover board on the magnetic carrier board, fixing the positions of the FPC and the PCB, and performing the reflow soldering on the FPC and the PCB through a reflow oven. The method for the assembly and the reflow soldering of the PCB and the FPC and the special positioning fixture thereof have the advantages of simple operation, good reliability, great improvement on the production efficiency and the production quality of the FPC and the PCB in the processes of assembling and soldering, and processing cost reduction.

Description

technical field [0001] The invention belongs to the field of electronic product manufacturing, in particular to a combined welding method of a printed circuit board and a flexible circuit board. Background technique [0002] With the rapid development of science and technology and the improvement of people's living standards, information, fashion, health, etc. have become important components of life, and all of these are closely related to electronic products. The increasing functions, reliable performance and the speed of updating of electronic products all provide more space and challenges for the manufacturing technology of electronic products. The amount of flexible circuit boards and their integrated circuits is also rapidly expanding, and there are also a large number of printed circuit boards (abbreviated as PCB in English, commonly known as hard boards, note: hereinafter referred to as PCB) and flexible circuit boards (FPC in English, commonly known as soft boards)....
