With the rapid development of mobile phones, electronics, communication industries, autonomous driving, etc., to a large extent, it has greatly promoted the continuous growth and rapid growth of the PCB board industry. People are concerned about the quality, number of layers, weight, precision, and The requirements for materials, colors, and reliability are also getting higher and higher.

It is also due to fierce market price competition, and the cost of PCB circuit board materials is also on a rising trend. In order to enhance the core competitiveness of the industry, more and more manufacturers choose to monopolize the market at low prices. However, behind these ultra-low prices, they are often obtained by reducing material costs and process manufacturing costs. In this way, the quality of the PCB circuit board itself cannot be reached.

Therefore, the PCB circuit board components are usually prone to cracks (cracks), Easy to scratch, (or scratches), its precision, performance and other comprehensive factors are not up to the standard, which seriously affects the reliability of the later PCB circuit board. It should be proved that the sentence is cheap and not good. It may not be good, but good Goods must not be cheap is an iron proof fact. Faced with the various PCB circuit boards on the market, there are two ways to distinguish the quality of PCB circuit boards; the first method is to judge from the appearance, and the other is from the PCB board. It is judged by its own quality specification requirements.

The primary factors to identify PCB circuit boards:

First: distinguish the quality of the circuit board from the appearance

Under normal circumstances, the outside of the PCB circuit board can be analyzed and judged by several aspects of the appearance;

1. Light and color.

The external PCB circuit board is covered with ink, and the circuit board can play the role of insulation. If the color of the board is not bright, and there is less ink, the insulation board itself is not good.

2. Standard rules for the size and thickness of PCB circuit boards.

The thickness of the circuit board is different from that of the standard circuit board. Customers can measure and check the thickness and specifications of their own products.

3. The appearance of the welding seam of the PCB circuit board.

The circuit board has many parts. If the welding is not good, the parts are easy to fall off the circuit board, which will seriously affect the welding quality of the circuit board. The appearance is good. It is very important to identify carefully and have a stronger interface.
