Abstract: A screen printing apparatus includes a squeegee driver that lifts/lowers a first lifting/lowering shaft and a second lifting/lowering shaft; a link mechanism including a swinging member that pivots about a horizontal axis by lifting/lowering operations of the first lifting/lowering shaft and the second lifting/lowering shaft; a squeegee unit installed to the swinging member; and a controller that controls at least a height of the squeegee unit and an orientation of the squeegee unit in a rotating direction by controlling the squeegee driver.

Abstract: A screen printing apparatus includes a print head, a moving base, and a mask cleaner. The print head prints a paste onto a board through the mask. The moving base moves under the mask in a horizontal paste scraping direction. The mask cleaner is mounted to the moving base and moves under the mask integrally with the moving base, and scrapes off the paste adhering to a lower surface of the mask. A base body is mounted to the moving base and includes a longitudinal side being horizontal and intersecting the paste scraping direction. Plurality of blades are detachably mounted to the base body and extending in the longitudinal direction and are arranged side by side in parallel to the paste scraping direction and cause a paste scraping edge protruding upward from the base body to come into abutment against the lower surface of the mask.

Abstract: A material management apparatus (management computer) includes a production plan acquirer that acquires production plan information including a type of a material (cream solder) for bonding a component to a substrate, the material being used for production of a mounting substrate obtained by mounting the component on the substrate; a material status acquirer that acquires material status information on the material preserved in a material preservatory which preserves an accommodating portion (solder pot) in which the material is accommodated; and a material preparation instructor that creates and transmits an instruction to prepare the accommodating portion to be put out from the material preservatory, based on the production plan information and the material status information.
