What you must know about 5557 wire-to-wire connectors

With the continuous development of wireless communication technology, "board-to-board" coaxial connectors are more and more widely used in the interconnection of wireless system modules, such as communication base stations, RRH, repeaters, GPS devices and other similar applications. After several generations of evolution, "board-to-board" coaxial connectors are developing from limited tolerance to large tolerance. Why 5557 wire-to-wire connectors, electrical connectors and their components are important supporting interface components in the equipment, scattered in various systems and parts of the equipment to ensure the transmission of signals and energy. The quality of the connection is directly related to the safe and reliable operation of the whole system.

5557 wire-to-wire connector, you must know about it. Recently, some new customers have received reactions that after welding the tactile switches purchased by other companies, the buttons cannot be returned. According to the experience of Huicheng Yuan wire-to-wire connector manufacturers, it is mainly divided into the following aspects: 1. The tactile switch shrapnel itself has no elasticity, so shrapnel with quality risks is used in order to reduce costs. Second, the welding temperature is too high. 1. The wave soldering temperature of the plug-in touch switch should not exceed 240 degrees Celsius/2 seconds or 235 degrees Celsius/5 seconds; 2. The reflow soldering of the SMD tactile switch should not exceed 270 degrees Celsius/2 seconds or 260 degrees Celsius/5 seconds; 3. The temperature of manual welding iron should be controlled between 320-350 degrees Celsius, and the welding time should not exceed 2 seconds; 4. Manual tin immersion welding, the welding temperature should not exceed 240 degrees Celsius/2 seconds; 5. The welding times of the same tactile switch should be controlled within 2 times. Exceeding the welding times will also cause quality hazards; 6. All welding processes must pay attention to preheating before welding. There are slight differences in the preheating of different PCB boards. 3. The touch switch is strongly squeezed during transportation or under high temperature conditions, resulting in shrapnel deformation. There will also be cases where the keys fail to rebound (this is relatively rare). 4. When doing high temperature resistance testing, the touch switch cannot be on for a long time, otherwise the shrapnel will be deformed and the button will not be able to bounce back.
