Teach you to make PCB circuit boards quickly
Paying attention to the trend of environmental protection informatization and the development of various environmental protection technologies, PCB factories can start with big data to monitor the company's pollution discharge and governance results, and find and solve environmental pollution problems in a timely manner. Keep up with the production concept of the new era, continuously improve resource utilization, and realize green production. Efforts to make the PCB factory industry realize an efficient, economical and environmentally friendly production model, and actively respond to the country's environmental protection policy.
Generally speaking, the production of PCB circuit board mainly involves the following steps: drawing a PCB circuit board diagram, printing it on the PCB board, corroding the PCB board, drilling holes, soldering components, and completing the test. It takes a relatively long time. Some users are very interested in how to make PCB circuit boards quickly. The following technicians will introduce how to make PCB circuit boards quickly:

There are many methods of making and processing circuit boards, but generally speaking, there are two methods of rapid board making that are often used, namely physical methods and chemical methods:

1. Physical method:

By using various knives and power tools, the unnecessary copper on the circuit board is carved out by hand. This method is laborious and has low accuracy, and only relatively simple lines can be used. The disadvantages are labor-consuming and time-consuming, difficult to control accuracy, and unrecoverable, which has high requirements for operation, and currently few people have adopted it.

2. Chemical method:

By covering the protective layer on the blank copper clad board, the unnecessary copper is etched away in the corrosive solution, which is the method used by most developers at present. There are many ways to cover the protective layer, mainly the following methods:

1. Manual painting: Use a brush or a hard pen to manually draw the shape of the circuit on the blank copper clad laminate, and then put it into the solution for direct corrosion after drying.

2. Adhesive stickers: There are various stickers on the market that are made into strips and discs. Different stickers can be combined on the blank circuit board according to the needs, and they can be corroded after they are tightly adhered.

3. Film photosensitive: Print the PCB circuit board diagram on the film through a laser printer. The blank copper clad laminate is pre-coated with a layer of photosensitive material (the coated copper clad laminate is sold in the market), and it is exposed, developed and fixed in a darkroom environment., It can be corroded in the solution after cleaning.

4. Thermal transfer: Print the circuit directly on the blank circuit board through a thermal transfer printer, and then put it into the corrosive liquid to corrode.

The chemical process is relatively complex, but the precision is controllable. It is currently the most widely used rapid plate-making method, but there are still many problems that need continuous improvement. Users can choose to use physical methods or chemical methods to make circuit boards according to their own conditions. You can order as little as 1 PCB from us. We will not force you to buy things you really don't need to save money.
