A method for solder resist plugging of a circuit board
By using an automatic hole-filling machine during the circuit board hole-filling process, the screen and motherboard are rotated alternately and air bubbles are expelled by gravity, which solves the problem of incomplete hole filling and achieves high-quality hole-filling effect.

Abstract
The application discloses a kind of methods for plugging hole of circuit board, the method is executed using automatic plug machine, and automatic plug machine at least includes screen, the method includes: providing the female board of circuit board;Female board includes at least one to be plugged hole position;Screen is placed in the side of female board towards gravity direction;Screen includes the through hole corresponding to at least one to be plugged hole position;Control screen and female board are alternately rotated to the included angle between the side surface of female board close to screen and horizontal plane is preset angle along clockwise and counterclockwise, and when the included angle between the side surface of female board close to screen and horizontal plane is preset angle, with screen as mask, fill in to be plugged hole position with through hole to resist welding material, until to be filled with resist welding material in plugged hole position.The technical scheme of the application, by the reverse direction plug-in mode from bottom to top, to realize that there is no air bubble in to be plugged hole position, enhance the saturation effect of resist welding material filling, improve plug-in quality.
