- Due to competition among enterprises in the market, the prices of PCB circuit board materials are also constantly rising. Many manufacturers monopolize the market with low prices in order to enhance market competitiveness. However, behind low prices is only the reduction of material costs and production processes, which is not good for the production of PCB circuit board materials. Now the editor will take you to the method of identifying the quality of PCB circuit boards.
Distinguish the quality of a circuit board from its appearance
In general, the appearance of PCB circuit boards can be analyzed and judged from three aspects;
1. Standard rules for size and thickness.
The thickness of a circuit board differs from that of a standard circuit board, and customers can measure and inspect it based on their own product thickness and specifications.
2. Light and color.
The external circuit boards are covered with ink, and the circuit board can serve as insulation. If the color of the board is not bright and there is less ink, the insulation board itself is not good.
3. Weld appearance.
Due to the large number of parts in the circuit board, if the welding is not good, the parts are prone to fall off, which seriously affects the welding quality of the circuit board. It is very important to have a good appearance, carefully identify, and a strong interface.
