The test of the surface and layout size of the terminal wire is usually carried out at the same time or at the same time. The quality of the production quality is good. On the one hand, it depends on its performance. However, the quality of the surface and layout size also accounts for a certain proportion. Surface and layout dimensions interfere with the function of the terminal wire.


1. Thinning locally, causing local fever, increased resistance, and accelerated insulation aging.

2. Black spots of oxidized rust, interfere with conductor joints, increase resistance, and easily deteriorate insulation.

3. A bump or scratch interferes with the mechanical strength of the conductor.


The surface test of the terminal wire is to test the surface phenomenon of the product, semi-product or document, and the dimensional test is to review each product according to the size of each part specified in the product standard. The layout test refers to the test of the layout of the various components of the terminal line. The surface test, such as the oxidation of copper wires, can interfere with the quality of the terminal line. The size can directly interfere with the product's function, such as the outer diameter of the conductor and its resistance. Relevant; insulation thickness and resistance are related to the withstand voltage level; strand pitch is related to the softness and firmness of the product. The test can reveal the production quality of the terminal wire, and I feel that there are difficulties in the production process. Therefore, the control surface and layout size are the guarantee of product performance.
