Data lines, whose role is to connect the mobile device and the computer, to achieve data transfer or communication purposes. Popular point that is connected to the computer used to access tools such as the transmission bell Picture class file. Now, with the rapid development of the electronics industry, the data lines has become an integral part of our lives. ? In accordance with the interface type classification com port and usb port 1, COM serial interface is also called, is connected to the back of a desktop computer, and is currently being phased out. The advantage is the low price, support Brush (part of the phone only with a serial cable Brush); drawback is split pull extremely inconvenient, does not support the laptop, the transmission speed is relatively slow. 2, USB interface is the main advantage is to facilitate fast and stable support for all types of computer; the disadvantage is the higher price band IC, another part of the data wire brush machine function is not supported. In the process of production data lines, the welding is also an essential part of a very important part, especially in the current more popular Apple phone lines, consumers want the product requirements for higher product to do well on the there is no market for this industry, currently has the majority of manufacturers have changed the welding process, laser welding machine has become everyone primary consideration. Applications of laser welding machine: sanitary industry: pipe fittings, adjustable joints, tees, valves, shower welding. Battery industry: Lithium batteries, battery packs, laser welding electrodes. Precision welding stainless steel, titanium and other materials glasses buckle bit, frame and other locations: the optical industry. Hardware industry: impeller, kettle, lock the handle shell, complex stampings, castings welding. Automotive industry: engine cylinder head gasket, hydraulic tappets seal welding, welding spark plugs, filters welding. Healthcare: Medical equipment, medical equipment stainless steel seal welded structure. Electronics: Solid State Relay sealed off welding, metal fittings and connectors welded structure welding, mobile phones, MP3 and so on. Welding motor housing and wired, fiber optic connector tabs and the like. Hardware Industry: Door shell welding, stainless steel products, mixing knife cylinder, wine and other liquor leak
