What are the test methods for board-to-board connectors? There are many board-to-board connectors in our life, mainly because it can improve efficiency and save costs; when applied, you need to understand the performance of the board-to-board connector and understand the specific operation methods to avoid problems during use. Today, Huicheng Yuan Electronics will be with you to understand the board-to-board connector testing methods. Separately as follows:

1, the mechanical function of the connection function, insertion force is the main mechanical function. Insertion force is divided into insertion force and pull-out force (pull-out force is also called separation force), which have different requirements. There are large penetration force and small separation force rules in the relevant specifications, which means that from the application point of view, the penetration force is small (and then there are low penetration force LIF and no penetration force ZIF structure), while the separation force, if too small, will affect the reliability of the contact. The insertion force and mechanical life of the board-to-board connector are related to the contact structure (positive pressure), the coating quality of the contact area (sliding friction coefficient), and the specification accuracy of the contact placement (alignment).2. Electrical FunctionsThe main electrical functions of the board-to-board connector include the contact resistance, insulation resistance, and electrical strength.1. Contact ResistanceThe high-quality board-to-board connector should have a low and stable contact resistance. Board to board connector contact resistance from a few milliohms to tens of milliohms ranging.2. Insulation resistance is a measure of the board to board connector contacts between the contacts and between the contacts and the shell of the insulating properties of the index, the order of magnitude from hundreds of megohms to thousands of megohms ranging.3. Dielectric strength, or withstand voltage, dielectric withstand, is the characterization of the board to board connector between the contacts or between the contacts and the shell of the ability to the rated test voltage.4. Other electrical functions. The above is all about the method of testing the board-to-board connector, I hope it will help you!
