With the continuous development of science and technology, various fields have achieved intelligence, so FPC circuit boards have also been widely used in various fields. With the continuous increase of FPC manufacturers , there will naturally be some merchants in terms of price and quality. Play tricks, then the question is, how to judge the quality of the FPC circuit board? There are two methods for Kabor Technology to judge the quality of FPC circuit boards:
First: Distinguish the quality of the circuit board from the appearance In
general, the appearance of the FPC circuit board can be analyzed and judged through three aspects;
1. Standard rules for size and thickness.
The thickness of the circuit board is different from that of the standard circuit board, and customers can measure and check according to the thickness and specifications of their own products.
2. Light and color.
The external 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.
3. The appearance of the weld.
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. Bad.
Second: A high-quality FPC circuit board needs to meet the following requirements:
1. The telephone should be easy to use after the components are installed, that is, the electrical connection should meet the requirements;
2. The line width, line thickness and line spacing of the line meet the requirements, To avoid circuit heating, open circuit, and short circuit;
3. The copper skin is not easy to fall off under high temperature;
4. The copper surface is not easy to oxidize, which affects the installation speed, and it will be broken soon after oxidation;
5. There is no additional electromagnetic radiation;
6. Appearance There is no deformation, so as to avoid deformation of the casing after installation and dislocation of the screw holes. Now it is all mechanized installation, the hole position of the circuit board and the deformation error of the circuit and the design should be within the allowable range;
7. High temperature, high humidity and special resistance should also be considered within the scope of consideration;
8. The mechanical properties of the surface To meet the installation requirements;
the above is the method of judging the quality of FPC circuit boards. When purchasing FPC circuit boards , you must keep your eyes open. Also, Kabor Technology is a company that specializes in FPC manufacturing, proofing, and mass production and processing. Mainly produces FPC single and double panels, FPC multi-layer boards and rigid-flex board production services. Our FPC circuit board proofing time is 3-4 days, and we also provide 24-hour express expedited proofing service. The lead time for FPC bulk is 7-10 days. In addition, Kabor Technology has also opened a green expedited channel for medical FPC orders to help consumers in the medical industry.
