Block for re-recognizing the shape of the adhesive on the printed circuit board after the adhesive has been applied to the printed circuit board in step
No, the allowable range for the reference area value S, and the allowable range for stringing are determined. In addition, it is decided to perform recognition evaluation for each N plate during production. When it becomes N plate in step,
Instead of unloading the printed circuit board, recognize the predetermined coating shape of the block and judge whether the area and threading are within the allowable range. If OK, the printed circuit board is unloaded and the next coating operation starts. If it is NG, a warning light or the like is turned on, the equipment is stopped, and information about the NG block and excess / deficiency / threading is displayed. The operator then decides and restarts production.
