Applications:

Dot gauge and wire gauge diagrams for quality inspection are convenient for quality inspectors to standardize uniform standards.
Various sizes, stain cards, and spot gauges are mainly used by the quality control department to determine the stain. It is used to measure and compare the area, diameter, width, length, and grayscale of the points, scratches, and other parts of the mobile phone case, LENS, and DISPLAY. Exceed the benchmark to determine whether an irregular point or line scratch can pass the inspection requirements. Through the designation of the appearance level, the point and wire gauge cards are used to objectively and quantitatively measure, so as to unify the appearance judgment standards of the entire company's products, reduce the judgment error between the parts receiving department and the supplier, and can accurately report to the supplier and The receiving department communicates the required product appearance without the need to make a limited sample and does not need to specify the appearance level!

About the film:

Try not to stick the film. The film should be hot-pressed at high temperature. The thermal expansion and contraction caused by high temperature may affect the accuracy.

How to use the point gauge:

When encountering an irregular point, first determine its roughly large point to find almost the same point, and then determine the shape of the irregular point. Then find the similarly sized rows on the point gauge, and then find the similar shape. Then cover it, if it can be covered, see if its size allows it to pass, if it can, then it can't.
When it is impossible to confirm whether a linear scratch can pass, cover the linear scratch with 25% gray interface. If the linear scratch cannot be seen and the length of the linear scratch is less than the specified length, it can pass, otherwise it cannot pass.
