What are the test methods for board-to-board connectors?

What are the test methods for board-to-board connectors? We have a lot of board-to-board connectors in our lives, mainly because it can improve efficiency and save costs; When applying, you need to understand the performance of board-to-board connectors and understand the specific operation methods to avoid problems in use. Today, Huichengyuan connector manufacturers will learn about the test method of board-to-board connectors with you.

Board-to-board connectors 1. Mechanical function In terms of connection function, the 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), and the requirements of the two are different. There are provisions in the relevant specifications that the penetrating force is large and the separation force is small, that is to say, from the application point of view, the penetrating force is small (then there are structures of LIF with small penetrating force and ZIF without penetrating force), and the separation force If it is too small, it will affect the reliability of contact. The insertion force and mechanical life of the plate-to-plate connector are related to the contact structure (positive pressure), the quality of the coating of the contact member (sliding friction coefficient), and the standard accuracy of contact placement (alignment). 2. The main electrical functions of board-to-board connectors include contact resistance, insulation resistance and electrical strength. 1. Board-to-board connectors with high contact resistance should have low and stable contact resistance. The contact resistance of board-to-board connectors ranges from a few milliohms to tens of milliohms. 2. Insulation resistance is an index to measure the insulation performance between the contacts of board-to-board connectors and between the contacts and the housing. Its size ranges from several hundred megabohms to several gigabohms. 3. Dielectric strength, or withstand voltage and dielectric withstand voltage, is the ability to characterize the rated test voltage between the contacts of a board-to-board connector or between the contacts and the housing. 4. Other electrical functions.
