Problems solved by technology

[0004] In the surface mount process of circuit boards, various components need to be mounted on the PVC circuit board. For components without pins, they can be directly mounted on the circuit board by the placement machine, which is convenient, fast and qualified. The rate is high; but for special components with pins, such as electrical connectors, it is necessary to insert the electrical connector into the circuit board first and then manually press it so that the pins are completely inserted into the circuit board, and then perform manual welding, and The work efficiency is low during manual welding, and the rework rate is high. At the same time, the amount of solder required is large, which wastes more production and processing costs. If rework is required, it can only be manually reworked twice.

Abstract

The invention discloses a high-efficiency soldering process of a circuit board connector in the field of soldering processes of electronic components on a circuit board. The high-efficiency soldering process comprises the following steps of: providing a PCB (Printed Circuit Board) jointed board; scraping soldering paste; mounting; mechanically installing a connector; carrying out reflow soldering; and carrying out QC (Quality Control) inspection testing and soldering an electronic wire. According to the high-efficiency soldering process, the step of manually soldering the connector is removed in the prior art, the PCB jointed board and the installed connector are placed in a soldering furnace of a reflux soldering machine for soldering, the original manual soldering is changed into the automatic soldering, thus the soldering quality of a soldering apparatus is improved, a series of procedures can be completed on the PCB jointed board, the production efficiency is increased, and the workers and the production cost which are required during production can be reduced.
