Abstract

The object of the invention is to provide a solder printing machine and a dirt checking method of a mask of a solder printing machine. The high-accuracy dirt checking of the mask can be carried out, even when the surface of the mask is scratched. The area of the mask (5) comprising a pattern hole (5a) is the checking part (S). The checking part can be irradiated from the first direction with respect to the mask hole, and the checking part can be shot, and therefore a first image (GZ1) capable of separating the solder (Hd) attached to the periphery of the pattern hole, the inner area of the solder, and other areas can be acquired. The checking part can be irradiated from the second direction different from the first direction, and the checking part can be shot, and therefore a second image (GZ2) capable of separating the solder area in the checking part and other areas. And the state of the solder of the mask can be detected by acquiring an overlapped image (GZ3) overlapping the two images (GZ1,GZ2).

Description

technical field [0001] The present invention relates to a solder printer for printing solder on a substrate through a pattern hole of a mask, and a method for inspecting contamination of a mask of the solder printer. Background technique [0002] The solder printing mechanism is such that a mask having a patterned hole is brought into contact with a substrate, and the squeegee is slid on the mask to scrape up the solder on the mask, thereby transferring the solder to the substrate through the patterned hole. Thereafter, the substrate is separated from the mask, and solder is printed on the substrate. [0003] In this type of solder printing machine, whenever solder printing is performed on the substrate, the solder adheres to the pattern hole of the mask, and as the solder adheres to the pattern hole, the opening area of ​​the pattern hole gradually decreases. Printing accuracy of the solder on the substrate deteriorates. Therefore, it is known that a mask after printing s...
