Embodiment 1

[0025] Such as figure 1 As shown, a PCB board welding method provided by the present invention includes:

[0026] a. Move the PCB board from the anti-static bag into the metal tray through the removal device;

[0027] b. Completely peel off part of the sheath 100 on the wire;

[0028] c. Solder the copper wire 200 of the stripped wire on the pad 400 of the PCB board 300.

[0029] Among them, the surface temperature of the electric welding resistance during welding is lower than 60℃; the total current during welding is 15±1mA; the welding process uses no-clean non-conductive flux or no-clean non-conductive solder paste.

Embodiment 2

[0031] As attached figure 2 , Attached image 3 And Figure 4 As shown, the present invention discloses a transfer device. The transfer device includes an upper fixed plate 1, an arc cam 2 with an inclined slope, and a top end drive connected to a rotating shaft 4 of a drive motor 3. The cam passes through a fixed part 5 is connected to the upper fixing plate; the center of the upper fixing plate is provided with a central hole 6, the shaft is inserted into the central hole, the bottom end of the shaft is shaped with a lower fixing plate 7, and the middle of the lower fixing plate is provided with a battery 8; Six fixed sliding holes 9 are uniformly installed on the lower fixing plate in the circumferential direction; the outer circumference of the rotating shaft is also provided with six removal assemblies 10, and an anti-static bag 11 is provided below the lowest point of the removal assembly.

[0032] The removal assembly includes an outer sleeve 12 and a sliding rod 13 slida...

Abstract

The invention provides a PCB welding method. The PCB welding method comprises the steps of a, completely stripping a sheath on an electric wire; and b, welding the stripped copper wire of the electricwire on a PCB. According to the invention, the sheath on the electric wire is completely stripped without damaging an internal copper wire, and meanwhile, the stripped electric wire sheath is not adhered to the copper wire and does not rebound, so that the welding of the electric wire is not influenced. Parallel connection of the electric wire and a PCB can realize only by designing the conventional bonding pad according to the conventional specification. In this way, the production efficiency can be greatly improved, the product tension is increased, and the attractiveness is improved.

Description

Technical field [0001] The invention relates to the field of PCB board processing technology, in particular to a PCB board welding method. Background technique [0002] At present, the traditional and conventional stripping and wires are connected to the PCB board pads. There are generally two ways. One is that the PCB board needs to be placed on a double row of pads. One end of the line is connected from the left pad, and the other end The wire is connected from the right pad. The other method is to cut the wires, twist the wires together, and then solder them to the PCB pads. The above two methods of wire stripping and welding will waste PCB board material on the one hand, and the firmness of the welding is not good, which will greatly affect the tension and appearance of the product. [0003] For example, as disclosed in Patent Document 1: CN201620815367.3, the utility model patent provides a PCB board welding structure, including a PCB board, a fixing structure, a pad and a s...
