Inspection standard of connector pin jack

　　In order to better make the connector pin and socket meet the needs of customers and ensure the quality of the product, it is also very important to develop a set of standard inspection specifications and evaluation criteria. Let’s take a look at the quality of the connector pin and socket. Bad:

　　1. Requirements of the testing environment

　　It is required that under normal light source conditions, the product is placed on the workbench, a distance of 30cm away, and the product is viewed at an angle of 45 degrees.

　　2. Packaging inspection standards

　　The packaging box of each product and the inner box must have the corresponding product name, specification, material number, quantity and environmental protection signs. The packaging must not contain mixed materials, wrong materials, humidity, deformation of the packaging box, and damage to the box. Corresponding protective measures must be taken when packaging.

　　3. Visual inspection standards

　　There is no deformation, bending, oxidation, stains, etc. on the pins or conductive parts of the pin jacks. Use a vernier caliper and a micrometer to check whether the length and outer diameter of the product are within the standard range.

　　4. Function check

　　Use a multimeter to check whether the resistance value at both ends of the conduction is within the standard. Put the pins of the product in a 270±5℃ tin melting furnace to resist soldering, take them out of the tin furnace, and measure its function after 3 hours. The function before the test is the same and will not be damaged by heat.

　　5. Precautions for functional inspection:

　　1. Wear protective gloves when taking inspections

　　2. Solderability and soldering heat resistance are based on 10PCS per batch
