Problems solved by technology

[0005] However, the temperature of wave soldering is about 220°C. High temperature is easy to damage the plug-in device, cause deformation of the PCB board, or cause pollution to the PCB board. The quality stability of the printed circuit board after soldering is poor, so wave soldering is now used to fix the plug-in device. very few

Embodiment Construction

[0033] The specific implementation manner of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

[0034] In the present invention, the soldering carrier made of high-temperature-resistant materials is used to protect the plug-in device and the PCB board through the soldering carrier, and the wave soldering is completed at one time. The welding efficiency is high, and the soldering quality is good at the same time. cost.

[0035] The soldering carrier includes a carrier plate, a bottom plate and a cover plate used to cover the plug-in on the PCB board. The carrier plate is located between the bottom plate and the cover plate; after fixing the PCB board between the carrier plate and the bottom plate, the carrier plate Fasten with the base and cover.

[0036] The two sides of the PCB board are the board surface and the board bottom respectively, the board surface plug-in is inserted into the ...

Abstract

The invention discloses plug-in welding process on a PCB and a welding carrier. The welding process comprises the following steps: arranging the PCB on a carrier plate, wherein the board bottom of the PCB faces upwards, and the board face of the PCB faces downwards; inserting a horizontal type board bottom plug-in into the board bottom of the PCB; covering the carrier plate with the bottom plate, fixing the carrier plate to the bottom plate, covering a body of the board bottom plug-in with the bottom plate, locating a pin of the horizontal type board bottom plug-in in a welding hole in the bottom plate; turning over the carrier plate, wherein the bottom plate is below the carrier plate, inserting a board face plug-in into the board face of the PCB, extending a pin of the board face plug-in from the board bottom of the PCB, and locating the pin in a second welding hole in the bottom plate; covering the carrier plate with a cover plate, fixing the carrier plate to the cover plate, and pressing the board face plug-in through the cover plate; conducting wave-soldering at the positions of the first welding hole and the second welding hole corresponding to the board bottom of the PCB. The welding carrier comprises the carrier plate, the bottom plate and the cover plate, wherein the board face plug-in on the PCB is covered with the cover plate, and the cover plate is used for fixedly protecting the plug-in, so that the plug-in is fixed to the PCB with high quality through wave-soldering.

Description

technical field [0001] The invention relates to the technical field of PCB board manufacturing, in particular to a plug-in welding process on a PCB board and a welding carrier. Background technique [0002] The electronic components on the PCB mainly include plug-in devices and mount devices. The plug-in devices are divided into board-side plug-ins and board-bottom plug-ins according to their positions on the PCB. PCB board. [0003] At present, the welding process of board surface plug-in and board bottom plug-in adopts manual electric soldering iron welding or automatic welding electromechanical soldering iron welding. Manual electric soldering iron welding and automatic welding electromechanical soldering iron welding must use a large number of personnel plug-ins. Welding with one solder spot, the welding efficiency is slower and the quality is poor. [0004] In order to improve the welding efficiency, wave soldering is also used to solder the plug-in devices. The wave ...
