More and more boards are compressed into smaller and smaller chassis, there is a great demand for interlayer connectors. The need for more pins and smaller pads drives Connector companies to quickly and mass-produce. The biggest hidden problem is which surface-mount connector can provide the most reliable connection,after it is assembled and tested?
Almost every system engineer has experienced problems with surface-mount connectors, and It's not hard to understand the reason. Minimal contact terminals and increasingly thin printed circuit boards (PCB) made coplanar almost impossible to achieve. Imagine that although the distortion of the ultra-thin sandwich card is up to the IPC standard, the pin design of the surface mount connector is not good, resulting in the pin being unable to connect to the circuit board. Again, the design engineer must question and evaluate all aspects of the design of surface-mount connectors.
Remember to ask about pin formation, for example, in which position to press? Where do you bend? Note: the "bend" alloy will attempt to return to its normal state. Thus, if the surface pin is bent to 100% coplanar, it will likely not reach 100% coplanar when it reaches the assembly line.
Don't let your past unhappy experience discourage you from designing new surface-mount connectors. There are still excellent and reliable surface-mount connectors for I / O, cable-to-board, board-to-board, and even backboard applications. You may request the connector representative to weld the surfaced connector so that the test can be carried out in person. Examine individual samples carefully to create a degree of trust in the pin design. Further suggestion is to use a microscope. Make sure that all surface-mount connectors include some form of reliable PCB stress relief, such as soldering anchors or through-hole reflow pins. During the assembly phase, it is recommended that you work with connector manufacturers which can ensure coplanar and reputable pins.
Connector manufacturers who are able to supply solid and high-quality surface-mount connectors will be happy to provide you with all the tools you need to complete your decision. Once a decision is made, celebrate your wise choice and benefit from the choice of surface mount connectors together with your manufacturing engineers!(Prototype Circuit Board)
