Welding wire structure of USB circuit board end

Abstract

The invention discloses a welding wire structure of a USB circuit board end. The USB is equipped with a circuit board; a group of bonding pads which are insulated from each other is arranged at the circuit board end; the bonding pads are arranged at a certain spacing, and each bonding pad is welded with corresponding wires; the circuit board is further equipped with an inserting and drawing type welding wire cover; a group of barriers corresponding to the bonding plates in positions is arranged at the welding wire cover; when the welding cover is inserted into the circuit board, the barriers are positioned in the spacing of the welding pads to separate the bonding pads; the bonding pads expose to welded to the wire. The welding wire structure of the USB circuit board end has the beneficial effects that 1, the adjacent bonding pads can be avoided short circuit due to excessive welding tin or welding error during welding, thus the difficulty at welding is reduced, and the yield is increased; 2, the automatic welding applies, so that the production efficiency is further increased; in addition, the additionally arranged wire clamps can be clamped to fix the wire, so that the processing efficiency is further increased, and moreover, cold joint caused by the swinging of the wire during welding can be effectively avoided, and as a result, the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of connection structures of USB products, in particular to the welding structure of pads at the end of a USB circuit board and external circuits, and is especially suitable for USB Type-C products. Background technique [0002] With the popularity of a large number of electronic devices supporting USB, these devices mainly include tablet computers, mobile phones, digital cameras, mobile storage devices, etc., and USB has become the standard interface of these electronic devices. The new generation of USB interface has a change direction. This is the Type-C USB interface, which can support both front and back plugs, and transmits data with a strong signal. [0003] At present, the USB products commonly used in the market are connected to the wire through the circuit board (PCB board). There is a set of pads at the end of the circuit board. The pads have a certain distance from each other and are insulated and...

AI Technical Summary

Problems solved by technology

However, the distance between the current pads is usually very narrow, resulting in frequent solder adhesion and short circuit between the two pads during soldering. The scrap rate is high and the manufacturing cost is increased; It is difficult to achieve automatic welding, and the technical requirements of manual welding are very high, so the manufacturing efficiency is very low

[0004] In view of the above technical problems, the existing solution is usually to enlarge the pad spacing of the PCB board, which will inevitably increase the size and cost of the PCB board at the same time, which is not conducive to the low manufacturing cost and small volume development trend of USB.
