Problems solved by technology

At present, in order to install the camera module in portable devices such as mobile phones, the connecting pins on the connector are small in size and closely arranged. In the ESD test, when the electrostatic gun discharges each connecting pin, it is easy to damage the adjacent connecting pins. pins are also incorrectly discharged, making ESD test results inaccurate

Abstract

The invention discloses an ESD test tool for a camera module, and the tool comprises a fixing part which is used for fixing a to-be-tested camera module; an electric connection discharging part comprising a plurality of electric connection pieces which are correspondingly and electrically contacted with each connection pin on the camera module to be tested, and a plurality of discharging pieces which are electrically contacted with the gun head of the electrostatic gun to carry out an ESD test, and the discharging pieces and the electric connection pieces are electrically connected in a one-to-one correspondence manner; wherein the distance between the discharging pieces is greater than the distance between the connecting pins on the camera module to be tested, and / or the electric contactarea of each discharging piece is greater than the electric contact area of each connecting pin on the camera module to be tested. According to the ESD test tool, compact connecting pins on the cameramodule to be tested can be separated, so that the ESD test is more accurate and convenient, and the product quality is ensured. The invention also discloses an ESD test method of the camera module.

Description

technical field [0001] The invention relates to the field of camera testing, in particular to an ESD testing tool and testing method for a camera module. Background technique [0002] The camera module is an electronic device that is sensitive to static electricity. When it is subjected to electrostatic discharge from the connecting pins of its connector, it may cause abnormal operation, such as outputting a picture with broken lines, so it needs to pass ESD (electrostatic discharge) ) test to evaluate its electrostatic resistance. At present, in order to install the camera module in portable devices such as mobile phones, the connecting pins on the connector are small in size and closely arranged. In the ESD test, when the electrostatic gun discharges each connecting pin, it is easy to damage the adjacent connecting pins. Pins are also incorrectly discharged, making ESD test results inaccurate. So a test fixture is needed. Contents of the invention [0003] In order to...
