The solder mask is generally photosensitive, called liquid photosensitive ink. Generally green, black, white, red, yellow, blue and so on. Cover films are generally available in yellow, black and white. Black has good shading and white has high reflectivity, which can replace white oil black for backlight FPC soft board. FPC soft board can be solder masked with ink or solder mask with cover film.This product is black solder mask.
What is the Black Solder Mask Flex Cable?
A flexible board is a flexible circuit board, and a flexible board ink is an ink with bending resistance. In the past, FPC was produced with cover film, that is, dry film. Now many flexible circuit boards are produced with photosensitive ink or thermoset ink, so flexible circuit board ink is also called wet film.
The role of FPC solder mask
1. The FPC Flexible board ink is printed on the copper foil circuit on the surface of the circuit board, which isolates the copper foil from contact with the outside world and plays a role in surface insulation.
2. After the circuit board is produced, it has to go through multiple processes. In order to prevent the copper foil circuit from being damaged during transportation and production, a protective layer should also be printed to protect the circuit and prevent circuit scars.
3. After the circuit board solder mask ink is completely cured, it can well prevent conductive foreign objects from falling into the circuit and causing a short circuit.
4. FPC circuit board solder resist ink has the functions of anti-electroplating, chemical tin resistance and chemical gold resistance, and can also play a good role in solder resist in SMT.
Therefore, in general, FPC soft board solder mask ink is a layer of protective paint, which plays a protective role to a large extent.
