What are the processing methods of epoxy glass cloth board?
This is a common processing method in epoxy glass cloth board factories. Whether it is PCB test fixtures or PCB post-processing, they will go through “drilling”. Larger PCB factories usually set up their own drilling rooms, which usually follow the treatment. Tools are relatively close, and the work in the drilling room is not an easy job, but it is relatively free. Usually the consumables and equipment used in the drilling room are drilling rigs, drill nozzles, rubber particles, wooden backing plates, aluminum backing plates, etc., drilling nozzles The wear and tear of the backing plate is huge, and many small companies usually make a fortune by supplying a drill bit and a milling cutter to a factory;
In addition, the common way of drilling is the new LED lampshade retaining insulator. As an energy-saving industry, LED has been hailed in recent years, and LED is composed of many small lamps. This feature makes the application field of insulating board broaden again. , Generally, the processing method of LED-retained insulating parts is to drill and then gong a circle. The processing method is relatively simple and the market is huge, but the characteristics are that the grade is not high and the profit is low;
This is the most common and most common processing method on the market. General stores have a cutting machine for cutting boards, but this is usually relatively rough, and the tolerance can be controlled within 5mm. It is scary to say, I I have seen many shops or companies in Dongguan that do epoxy board. The company that has been doing it for more than 5 years is still using angle iron welding cutting boards. Dongguan is known as the manufacturing capital, and it seems that it is indeed very powerful. , This method has no technical content, but sometimes it is very *some. For example, sometimes one and a half pieces are divided into 8 pieces in normal calculations, which is a small waste, but those stores that sell boards have a way to divide each board. Cut into 10 small sheets, if the quantity is large, the profit will be very considerable;
3, milling machine/lathe
The products processed by this processing method are usually products such as parts, because milling machines and lathes are mostly used for processing hardware parts, but the slow processing speed of ordinary milling machines and lathes is a major feature, so if If you rely exclusively on this kind of epoxy board processing method, the company’s life will be greatly reduced. However, for jigs, these two types of equipment are safe, that is to say, if you process thick epoxy boards, milling machines and lathes Yes*;
4, engraving machine
Epoxy glass cloth board processing method The computer engraving machine is composed of three parts: the computer, the engraving machine controller and the engraving machine host. Its working principle is: design and typesetting are carried out through the engraving software configured in the computer, and the information of the design and typesetting is automatically transmitted to the engraving machine controller by the computer, and then the controller converts this information into a stepping motor or The signal (pulse train) with power of the servo motor controls the host of the engraving machine to generate the X, Y, Z three-axis engraving tool path base diameter. At the same time, the high-speed rotating engraving head on the engraving machine cuts the processing material fixed on the worktable of the host machine through the tool configured according to the processing material, and can engrave various flat or three-dimensional relief graphics and text designed in the computer. , Realize the automation of engraving operations.
