A screen printing method of the present disclosure includes: a step of performing printing of a first viscous fluid through a screen on the first circuit board using a first squeegee and a first holding member; and a step of performing printing of a second viscous fluid through the screen on the second circuit board using a second squeegee and a second holding member. As described above, in the printing of the first viscous fluid on the first circuit board and the printing of the second viscous fluid on the second circuit board, squeegees and holding members different from each other are used, and thus, the first viscous fluid and the second viscous fluid do not mix with each other. As a result, it is possible to perform printing of different types of viscous fluids on the first circuit board and the second circuit board.

There is provided a screen printer including: a squeegee device for spreading a cream solder over a mask having formed thereon a printing pattern configured of a plurality of through holes to force the cream solder through the printing pattern; a clamping device for holding a board that is conveyed to be placed under the mask; and a lift device for disposing the board with respect to the mask in relation to a vertical direction, wherein the clamping device includes a pair of clamping portions for holding the board therebetween from a width direction, wherein the pair of clamping portions includes individually detachable clamping members that are brought into abutment with lateral end faces of the board, and wherein the clamping members individually have two or more clamping surfaces that are brought into abutment with the board in such a way that the clamping surfaces can be converted.

Screen printer

A printing apparatus of the present disclosure is for performing printing of a viscous fluid onto a print target using a screen mask, the printing apparatus including: a moving section configured to perform at least one of moving an exchangeable member to an exchange position or loading and unloading of the exchangeable member, for at least two types of the exchangeable member that, out of a cartridge configured to house the viscous fluid, a squeegee, a screen mask, a cleaning member used to clean the screen mask, and a support member configured to fix the print target, include at least one out of the cartridge, the squeegee, and the cleaning member; and an exchange control section configured to control the moving section to perform exchange processing of exchanging the exchangeable member.

Printing apparatus and accommodation apparatus

An object is to provide a screen printing machine capable of one-way printing on multiple boards. Solder collecting device includes collecting plate moving device, collecting plate, and scraper.

A first conveyor belt and second conveyor belt are disposed on guide rail which is disposed so as to extend in a circuit substrate conveyance direction. Then, the circuit substrate supported by both the conveyor belts of the first conveyor belt and the second conveyor belt is held by substrate holding device, and work is performed on the held circuit substrate. In the transfer device having such a structure, for example, when the circuit substrate on which an operation has been completed is conveyed out by the second conveyor belt, a new circuit substrate is conveyed into the transfer device by the first conveyor belt. In this way, it is possible to perform printing work on a new circuit substrate at an early stage and shorten a cycle time.
