PCB factory tells you how to select solder paste thickness gauge

Solder paste thickness gauge is a device that uses laser non-contact three-dimensional scanning dense sampling technology to measure the thickness, area, volume, short circuit and offset of solder paste (red glue) printed on PCB. Solder paste thickness gauge is mainly divided into online type and offline type. Solder paste thickness gauge plays a very important role in SMT industry. It can calculate the thickness change of solder paste and draw the thickness distribution map of solder paste, which can monitor the printing quality of solder paste and reduce the defective rate. However, different solder paste thickness gauges can be good or bad. How to choose a good solder paste thickness gauge? Next, we will tell you through five principles

Next, we will tell you how to choose a good solder paste thickness gauge through five principles.

The indicators for distinguishing the advantages and disadvantages of the solder paste thickness gauge focus on resolution, measurement repeatability, inspection time, operability and GR&R (repeatability and reproducibility)

1. Resolution: The resolution directly affects the image quality. Using a camera with high resolution can reduce the workload of debugging and checking programs, and also reduce the false alarm rate.

2. Determination repeatability: The closer the results of continuous measurement of the same measured object are to each other in the same measuring environment, the same measuring instrument, the same location and in a short time, the better the product quality is.

3. Inspection time: the inspection speed of the tester also directly affects the production speed, so it is necessary to have a fast inspection time for a good equipment.

4. Operability: different operating terminals have different difficulties in operation. Only with more humanized operation, operators can get started more easily, which can reduce errors in human operation.

5. GR&R: The higher the repeatability and reproducibility, the lower the measurement error and the closer the measured value is to the true value.

These five principles are the most basic indicators to distinguish the advantages and disadvantages of solder paste thickness gauge. At present, the well-known solder paste thickness gauge manufacturers at home and abroad mainly include Kouyoung and Cyber Optics in South Korea, SAKI in Japan and Delutai in Taiwan, China, China.
