Abstract

The invention discloses a welding method for a PCB and an FPCB. The welding method comprises the following steps of S1, enabling the FPCB to be fixedly attached to the surface of the PCB through a circuit board carrier, and enabling bonding pads in the attached position to be aligned and attached; S2, printing tin paste on the bonding pads of the attached FPCB and PCB through a steel net; S3, mounting electronic components on the corresponding bonding pads; and S4, putting the PCB and the FPCB which are attached together through the carrier into reflow soldering equipment to be heated to realize the welding of the PCB and the FPCB and the welding of the corresponding electronic components at the same time. The invention discloses a welding structure for the FCB and the FPCB. The welding between the FCB and the FPCB realized by the welding method and the welding structure has the advantages of high production efficiency, capability of reducing cost, and stable welding quality.

Description

technical field [0001] The invention relates to surface mount technology (SMT, Surface Mount Technology), in particular to a method for realizing welding between a PCB and an FPCB and a corresponding welding structure of the PCB and the FPCB. Background technique [0002] Circuit boards can be divided into two categories: PCB and FPCB; there are two types of current PCB and FPCB welding modes: [0003] Type 1: PCB and FPCB are soldered and connected by a soldering machine or a heat press: [0004] Disadvantages: 1) During the soldering process, the solder is prone to tin beads due to rapid heating and cooling, resulting in functional short circuits and easy burns on the protective film on the surface of the FPCB; 2) Poor consistency of solder joints and unstable quality; 3) PCB mounting components Offline welding with FPCB after welding is completed, which needs to be divided into two processes, so the production efficiency is low and the manufacturing cost is high; 4) It i...
