A method for screen printing of a material on a substrate is provided. The method includes moving a process head assembly having at least one deposition device from a first position to a second position to perform a stroke, wherein the stroke includes at least a first phase for material processing of a material on a screen device using the at least one deposition device and a second phase for a material transfer from the screen device to the substrate. The at least one deposition device moves in a first direction in the first phase. At least one device moves in a second direction perpendicular to the first direction in the first phase. The at least one deposition device and the at least one device simultaneously move during at least a part of the first phase. The at least one device is selected from the group including the at least one deposition device, a material processing device, the screen device, and a substrate support.

A component-mounting device includes a mounting head, a discharging portion, and a paste receiving portion. The mounting head holds a component. The discharging portion applies paste by spraying to the component held by the mounting head. The paste receiving portion is provided on the mounting head and captures paste that has been discharged from the discharging portion and has failed to reach the component.

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.

This invention provides methods for the processing of platinum metallized high temperature co-fired ceramic (HTCC) components with minimum deleterious reactions between platinum and the glass constituents of the ceramic-glass body. The process comprises co-firing a multilayer laminate green ceramic-glass body with via structures filled with a platinum powder-based material in a reducing atmosphere with a specified level of oxygen partial pressure. The oxygen partial pressure should be maintained above a minimum threshold value for a given temperature level.

A paste retainer system is disclosed for use in a paste printing system, said paste retainer system comprising a flexible attachment means for attaching a paste retainer to a squeegee holder via a flexible main body.

A screen printer including a squeegee device to spread from above solder paste on a stencil; a clamp device to grip a board conveyed to a position below the stencil by a board conveyance member that is flat and provided with a board holding portion in a central opening portion, the clamp device gripping the board via the board conveyance member; a board supporting device to support the board from below and move the board in a vertical direction inside the clamp device; and a raising and lowering device to move the board supported inside the clamp device in the vertical direction and position the board at a printing position, and the clamp device is provided with a board printing guide member to be removably attached to an upper end of a pair of clamp members to sandwich the board conveyance member in a widthwise direction.

The application relates to a doctoring unit for a printing apparatus for printing flat substrates, in particular circuit boards, wafers, or solar cells, comprising two doctor blades, which extend parallel to one another and are pivotably mounted. It is provided that the doctor blades are operatively connected to a gearing, which is formed in a self-locking manner and can be coupled or is coupled to a drive device.

A printing screen method includes: providing at least one printing scraper assembly, wherein the printing scraper assembly has a printing scraper and a pressure sensing feedback system; placing at least one printing screen on a substrate; detecting and supplying a pressure value between the printing scraper and the printing screen during printing by the pressure sensing feedback system; and comparing the supplied pressure value and a predetermined pressure value, and changing the pressure between the printing scraper and the printing screen if a difference between the feedback pressure value and the predetermined pressure value is larger than a predetermined threshold. An imprinting apparatus implementing the printing screen method is also provided.

In a mask printing machine, a target through hole, which is at least one of multiple through holes formed on the mask, is imaged by an imaging device when the board is below the mask and is at a separated position that is separated from the mask, and when the board is at a contact position in which an upper surface of the board contacts a lower surface of the mask, respectively. Based on a captured image, when the board is at the separated position, and a captured image when the board is at the contact position, it is possible to acquire the movement state of at least one target through hole when the board is lifted from the separated position to the contact position.

A paste dispensing transfer system of a stencil printer is configured to print an assembly material on an electronic substrate. The transfer system includes a paste cartridge mechanism coupled to a print head assembly of the stencil printer, and a rotary indexing mechanism coupled to a frame of the stencil printer. The paste dispensing transfer system is configured to transfer a used paste cartridge from the print head assembly to the rotary indexing mechanism supported by the frame and to transfer a new paste cartridge from the rotary indexing mechanism to the print head assembly.
