In the production of circuit boards, green oil bridges, also known as solder resist bridges and solder resist dams, are "isolation belts" made by circuit board factories to prevent short circuit of SMD component pins. In order to control the green oil bridge of the FPC flexible board (FPC flexible circuit board), it needs to be controlled during the solder mask process. There are two kinds of solder mask materials for FPC soft board: ink and cover film.
The role of FPC flexible circuit board solder mask
1. Surface insulation;
2. Protect the line and prevent line scars;
3. Prevent conductive foreign objects from falling into the circuit and cause a short circuit.
The ink used for solder mask is generally photosensitive, which is 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, and can be used for backlight FPC soft board (FPC flexible circuit board) instead of white oil black. FPC flexible board (FPC flexible circuit board) can be solder masked with ink or with cover film.
