About the performance of the connector

① Contact resistance High-quality electrical connectors should have low and stable contact resistance. The contact resistance of the connector varies from a few milliohms to tens of milliohms.

② The insulation resistance is an index to measure the insulation performance between the contacts of the electrical connector and between the contacts and the housing, and its order of magnitude ranges from hundreds of megohms to thousands of megohms.

③ Dielectric strength, also known as withstand voltage and dielectric withstand voltage, refers to the ability to withstand the rated test voltage between the connector contacts or between the contacts and the shell.

④ Other electrical properties. Electromagnetic interference leakage attenuation is to evaluate the electromagnetic interference shielding effect of the connector, which is generally tested within the frequency range of 100MHz ~ 10GHz.

Test the board-to-board connector

It is an important item in manufacturing and also a guarantee for the quality of board-to-board connectors. Board-to-board connectors with unqualified performance, process and quality cannot be assembled and shipped, and must be repaired or recycled. In the board-to-board connector test, the shrapnel microneedle module can play the role of signal transmission and connection, has a unique connection method for the male and female seats, has stable and reliable performance, and does not cause any puncture marks on the connector.

The shrapnel microneedle module aims at the male and female seats of the board-to-board connector, and the sawtooth shrapnel can be used to contact the male seat of the board-to-board connector, and the pointed shrapnel can be used to contact the female seat of the board-to-board connector, so as to maintain the stability of the connection. The head shape is made according to the characteristics of the male and female seats, and the head is also provided with a self-cleaning design, so as to avoid the interference of impurities, so that the test is free of pollution, and the connection.

When the board-to-board connector is tested, the elastic sheet microneedle module can transmit the current within the range of 1-50 A, the voltage is constant, the current flows in the integrated elastic sheet, and the overcurrent is stable without attenuation. The board-to-board connector with a small pitch needs a module that can adapt to a small pitch. In the pitch of 0.15mm-0.4mm, the shrapnel microneedle module can maintain good performance, and the needle will not be broken even if it is connected for a long time. The average service life is up to more than 20w times, and the performance is stable and reliable. It can also improve the test efficiency of the board-to-board connector!
