For purchasers, in their work experience, there must be project procurement of wire-to-wire connectors, but have you carefully understood this product before purchasing wire-to-wire connectors? Dosin hardware and electronic engineers pointed out that with the rapid 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 in communication base stations, RRHs, repeaters, GPS It can be found in applications such as devices. After several generations of board-to-board product iterations, "board-to-board" coaxial connectors are evolving from limited to large tolerances.
A. The wire-to-wire connector shrapnel itself has no elasticity. In order to reduce the cost, the shrapnel with hidden quality problems is used.
B. The welding temperature of the wire-to-wire connector is too high.
1. The wave soldering temperature of the plug-in tact switch should not exceed 240 degrees Celsius/2 seconds or 235 degrees Celsius/5 seconds;
2. Do not exceed 270 degrees Celsius / 2 seconds or 260 degrees Celsius / 5 seconds after reflow soldering of the patch tact switch;
3. The temperature of manual soldering iron should be controlled between 320-350 degrees Celsius, and the soldering time should not exceed 2 seconds;
4. Manual dip tin soldering, the soldering temperature should not exceed 240 degrees Celsius / 2 seconds;
5. The welding times of the same tact switch should be controlled within 2 times. Exceeding the welding times will also cause hidden dangers in quality;
6. All welding processes must pay attention to preheating before welding. There is a little difference in the preheating of different PCB boards.
C. The wire-to-wire connector is strongly squeezed during transportation or under high temperature conditions, resulting in deformation of the shrapnel. There will also be cases where the keys cannot be rebounded (this situation is relatively rare).
D. When doing high temperature resistance test, the wire-to-wire connector cannot be in a conducting state for a long time, otherwise the deformation of the shrapnel will cause the button to fail to bounce back. After reading the above, you should have a clear understanding of the basic concepts of wire-to-wire connectors. For more professional knowledge about wire-to-board connectors, Dosin will continue to edit and publish the topic of online-to-board connectors. to share with you.
