The role of point rulesCan an irregular point or linear scratch be determined to meet the inspection requirements.

Composition of Point RulesThe size of a dot gauge is usually the size of an A4 paper, consisting of a dot area, a 25% gray interface, and a scale line.

The usage method of point gaugeWhen encountering an irregular point, first determine its approximate size and find similar points on the point gauge. Then determine the shape of the irregular point, and in the rows where similar sized points were found on the point gauge earlier, find points with similar shapes. Then cover it up. If it can be covered, check if its size allows it to pass through. If it can, it can pass, otherwise it cannot pass.

Our company specializes in designing and producing various stain cards/point gauges Gauge Comparison film Mainly used by the quality control department to determine stains, it is used to measure and compare the area, diameter, width, and length of points and scratches on components such as phone cases, LENS, and PLAY Whether the color of the product exceeds the standard, applicable to LCD, PCB board, optoelectronics, and electroplating Communication industry, etc The combination of dots, lines, and surfaces includes the size, diameter, and length standards of the dots, as well as the depth of the dots Plastic transparent, A4 paper size
