In a screen printing that shifts squeegees in a horizontal direction while abutting the squeegees against a mask, and slides the squeegees on the mask, and scrapes up the paste on the mask so that opening portions are filled with the paste to transfer the paste onto the substrate, a larger amount of paste Ps is supplied to regions in which the paste is scraped up by the end portions of the squeegee than a region in which the paste is scraped up by a center portion of the squeegee on the mask.

Screen printing machine and screen printing method

A light receiving sectionreceives a measurement beam, which is cast from a light projection sectionand partially blocked by cream solderscraped up by a squeegee, whereby a sensormeasures a one-dimensional size of a predetermined region of a cross sectional profile of the cream solderas a cross sectional paste length and takes the cross sectional paste length as an index for an amount of residual cream solder. The amount of residual cream soldercan be numerically grasped at all times, so that versatility and accuracy in detecting the amount of residual cream soldercan be assured.

Screen printer and method for detecting amount of residual paste

At the two ends of a pair of clamping members () which sandwich and clamp a board () from the Y direction, mask supporting members () forming a rectangle frame are disposed, and a screen mask () is supported from below by the mask supporting members () in a state that the board () abuts against the under surface of the screen mask (). A downwards bending of the screen mask () can be prevented, and the time and labor of maintenance can be decreased by preventing the deposits of paste on the screen mask () that occur due to the bending.
