How to identify the FPC qulity ?

FPC, also known as flexible circuit board, flexible circuit board, or flexible circuit board for short; it is a kind of highly reliable, insul Flexibility of printed circuits. The flexible circuit board has the characteristics of small size, light weight and high flexibility; it is a special board with certain technical thresholds and operational difficulties, and the cost is also high. So, what are the ways to distinguish the quality of FPC circuit boards?

First: Identify the quality of FPC from the appearance:

1. Standard size and thickness.

Customers can measure and check whether the product conforms to the thickness and specifications specified in the production drawings.

2. Light and color.

The circuit board is covered with ink. If the color of the board is not bright and there is little ink, it means that the quality of the board itself is not good.

3. The appearance of the weld.

Due to the large number of parts on the circuit board, if the welding is not good, the parts will easily fall off. If you carefully identify it, you can have a preliminary judgment on the quality.

Second: High-quality FPC has the following requirements:

1. The components are required to be easy to use after they are installed, that is, the electrical connection must meet the requirements;

2. The line width, line thickness and line spacing of the line meet the requirements to avoid line 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;

5. No additional electromagnetic radiation;

6. The appearance of the circuit board is not deformed, and the error of the hole position and circuit design is within the allowable range;

7. It is required to be resistant to high temperature, humidity and special environments;

8. Meet the installation requirements of mechanical properties.
