A screen printing apparatus includes a pair of clampers that clamp a substrate, a mask plate contacted to the substrate, a pair of squeegees provided above the mask plate vertically, and a squeegee controller that selectively controls one of the pair of squeegees to move in the horizontal direction in abutment against the mask plate so that the selected one of the pair of squeegees slides on the mask plate.

A solder supply device provided with a solder cup housing liquid solder that is tubular and open at one end; a nozzle section, for ejecting solder from the solder container, that is inserted into the solder container; a flange section that is provided on an outer circumferential section of the nozzle section and that is engaged inside of the solder cup; and an outer tube that demarcates an air chamber with the bottom surface of the solder cup. Solder is supplied from the tip of the nozzle section by the solder cup and the flange section being relatively moved by supplying air to the air chamber. Solder is supplied from the solder container without using an air cylinder, electromagnetic motor, or the like.

Solder supply device includes solder cup that is tubular and open at one end, nozzle section for ejecting solder from the solder cup, flange section that is fixedly provided on an outer circumferential section of the nozzle section and that is engaged inside of the solder cup, and inner tube an end of which holds the nozzle section and the other end of which extends from the opening of the solder cup; the flange section is formed from material that is elastically deformable and the flange section is engaged inside the cup with an outer edge section of the flange section in an elastically deformed state. The elastic force arising between the outer edge section of the flange section and the solder cup is smaller than the holding force of the nozzle section by the inner tube.

An applying apparatus that applies a flux liquid includes: a nozzle from which the flux liquid is injected; and an intake and exhaust unit that sucks the flux liquid injected from the nozzle through an intake port and exhausts a gas through an exhaust port. The intake and exhaust unit has a filtering unit that filters the flux liquid sucked through the intake port and through which the gas passes before the gas reaches the exhaust port. The filtering unit is movably provided within the intake and exhaust unit so that when installing/removing the filtering unit with respect to the intake and exhaust unit, the filtering unit moves in a direction substantially parallel to a direction in which the flux liquid is sucked through the intake port and in which the gas is exhausted through the exhaust port.

A method of dispensing paste for a printer using a paste dispensing apparatus is provided. The paste dispensing apparatus includes a reservoir for storing a paste for a printer. The reservoir includes a stirrer for stirring the paste. The paste dispensing apparatus includes a receptacle for receiving paste from the reservoir. The paste dispensing apparatus includes a closable passage from the reservoir to the receptacle. The closable passage is changeable between an open state and a closed state. In the open state, the receptacle is fluidly coupled to the reservoir so that paste can pass from the reservoir to the receptacle. In the closed state, the receptacle is fluidly decoupled from the reservoir so that the paste is prevented from passing from the reservoir to the receptacle. The paste dispensing apparatus includes a pusher for pushing paste out of the receptacle. The method includes transferring a first volume of paste from the reservoir to the receptacle while the closable passage is in the open state. The method includes, after the transferring, changing the closable passage from the open state to the closed state. The method includes, after the changing, performing a first discharging operation by the pusher to discharge a first amount of paste from the receptacle while the closable passage is in the closed state.

A dual function tooling tray for a stencil printer includes a perimeter frame, a first frame member spaced from a first side of the perimeter frame, a second frame member spaced from a second side of the perimeter frame, and a third frame member extending between and secured to the first frame member and the second frame member. The third frame member is configured to support at least one squeegee blade assembly. The tooling tray further includes a first support secured to the first frame member and a second support secured to the second frame member. The first support and the second support are configured to support a tooling plate. The tooling tray further includes a third support secured to the first frame member and a fourth support secured to the second frame member. The third support and the fourth support are configured to support a tooling plate.

A paste supply apparatus includes a pot holding part that holds a paste pot that includes a tubular container which receives paste and is provided with a through hole in a bottom part of the tubular container and an inner lid movable inside the tubular container, in a posture in which the paste can be extruded downwardly from the through hole, an extrusion member configured to hold the inner lid of the paste pot held in the pot holding part, an inner lid holding part with which the inner lid is held in the extrusion member, an extrusion member elevation part that upwardly and downwardly moves the extrusion member, and a stopper with which the container upwardly moved together with the inner lid collides when the extrusion member holding the inner lid is pulled up by the extrusion member elevation part.
