The use of PCB laminating machine

2022-06-30 16:48

The pressing process is mainly used in the PCB laminating machine, and the uniformity of the pressure and temperature of the PCB laminating machine has a great influence on the quality of the pressing, and how to regularly detect its stability through tests, so as to ensure the pressing quality of the product. Xiaobian today on this issue of the relevant analysis, comprehensive Internet information obtained the following results:

PCB Laminator Pressure Uniformity Test Method: For the pressure uniformity test, there is a special induction paper, which is equivalent to the old high copy paper. The effect is better, but the price is very expensive. In addition, standard lead strips can be arranged in the press for testing. After the test, the uniformity of the press can also be known by measuring the residual thickness of each section of each lead strip, and the numerical value can be quantified. In addition, the more old-fashioned method is to use copy paper on a piece of white paper, press the operation, and then check the impression left on the white paper after pressing, you can know which position of the press platform is insufficient, which position pressure is even.

Temperature uniformity test method: use thermocouple thermometer, make several thermocouple wires, then according to the position of the platform, use nine or more points to place, record the temperature data of each position after pressurization, and then make the statistical data into the form of a chart, which can intuitively and conveniently see the temperature uniformity of the whole pressing platform. At the same time, the change of temperature reproducibility can be obtained through multiple tests, so as to systematically evaluate the performance of the press.
