Welding method of iPhone data line for help

First, manual welding.

It is the way that workers weld with an electric soldering iron in one hand and a cut wire in the other. This is the most primitive welding method, which is inefficient, wastes a lot of manpower and material resources, and the quality cannot be guaranteed. Therefore, in today's emphasis on efficiency, this mode of production is gradually being eliminated.

Second, the machine welding

1, using a single automatic welding machine for welding.

The method is to use the current automatic welding machine for welding. We make the fixture in advance, fix the USB on the fixture, and then put it on the automatic welding machine together with the fixture for welding. A fixture can hold a variety of products, so that a person can basically operate a machine. It is characterized by good welding quality and acceptable output, and a point can be welded in about 1 sec.

2. Use multi-head automatic welding machine for welding.

The method is to use a PLC to control 4-8 welding heads to weld at the same time, so as to ensure that one point can weld one or two products. The premise is that the product fixture should also be made in advance, and many people should arrange the cables in the previous stage. Its characteristics are high welding speed and high welding quality, which can greatly save manpower.

3. Hot pressing welding.

The so-called hot pressing is a common form of hot pressing. The head comes down at the same time and four solder joints are welded at a time. At present, there are people who use this method, but it is not very mature, mainly because the quality of welding products can not be guaranteed and the defective rate is relatively high. It is characterized by small one-time investment and fast welding, but the defective rate is relatively high.
