How to Determine Whether the FPC Flexible Board Is Good or Bad

FPC is the abbreviation of Flexible Printed Circuit, also known as flexible circuit board, flexible printed circuit board, flexible circuit board, or FPC for short; with high wiring density, light weight, thin thickness and other characteristics.

How to Determine Whether the FPC Flexible Board Is Good or Bad How to Determine Whether the FPC Flexible Board Is Good or Bad

The criteria for judging the good and bad of FPC flexible board

1.The size and thickness of the standard rules

Line board on the standard circuit board thickness is different sizes, customers can measure and check the thickness and specifications according to their own products.

2. Light and color

External circuit boards are covered with ink, circuit boards can play the role of insulation, if the board is not bright color, less ink, insulation board itself is not good.

3. The appearance of the weld seam

Circuit board due to more parts, if the welding is not good, parts easy to fall off the circuit board, seriously affect the board’s welding quality, the appearance of good, careful identification, interface strong point is often important.

Quality FPC circuit boards meet the requirements of:

1. The requirements of the components installed on the telephone to work well, that is, the electrical connection to meet the requirements;

2. The line width, line thickness, line distance to meet the requirements, so as to avoid line heating, disconnection, and short circuit;

3. The high temperature copper skin is not easy to fall off;

4. Copper surface is not easy to oxidation, affecting the speed of installation, oxidation shortly after the use of bad;

5. No additional electromagnetic radiation;

6. No deformation of the shape, so as not to install the shell deformation, screw hole misalignment. Now are mechanized installation, the hole position of the circuit board and the line and the design of the deformation error should be within the allowable range;

7. And high temperature, high humidity and resistance to special should also be in the scope of consideration;

8. The mechanical properties of the surface should be in line with the installation requirements.
