In order to make d-sub connectors manufacturer china meet customer requirements and ensure product quality, it is also very important to develop a set of standard inspection specifications and evaluation standards.

Test environment requirements

Under normal light source conditions, place the product 30CM away from the workbench and view the product at a 45 degree Angle.

Packing standard

The packaging box and inner box of each product must have the corresponding product name, specification, material number, quantity, and be affixed with the environmental protection mark. The package must be free of mixed packing, wrong materials, moisture, deformation of the packing box, and damage to the box. Appropriate protective measures must be taken for each package.

Visual inspection standard

No distortion, bending, oxidation, stains, etc. On the conductive part of a pin or pin socket. Use vernier calipers and micrometers to check that the length and outside diameter of the product are within the standard range.

Functional check

Use a multimeter to check whether the resistance value of the conductive terminal is within the standard range. Put the product pin into a 270±5℃ tin melting furnace for resistance welding, remove it from the tin furnace, and test its function 3 hours later. The results are the same as before the test, there is no heat loss caused by the connection.

Precautions for functional inspection:

1. Wear protective gloves during inspection.

2. Weldability and welding heat resistance should be subject to 10 pieces per batch.
