Screen printing apparatus and method

Номер: GB0002553396A
Принадлежит:

A screen printing apparatus for screen printing onto a substrate S comprises a printing screen unit with a printing screen 217 and a frame 211 for holding the printing screen in a substantially planar primary configuration: a support 203 for the substrate; a moveable print head 205 for contacting and sweeping across a printing region of a first surface of the printing screen; and an engagement structure 220 mounted to contact a region of a surface of the printing screen which lies outside any part of the printing region and which is drivable to move a portion of the printing screen in a direction orthogonal to the screen. Moving the screen away from the substrate improves separation between the printing screen and substrate. Moving the screen towards the substrate before printing can pre­tension the screen to reduce the tension which the print head has to overcome. There is also provided a method of screen printing which includes the step of moving at least a portion of the screen in a ...

Determining component height deviations

Номер: GB0002602011A
Принадлежит:

Heights of components or parts thereof are measured within a printing machine by measuring their relative rather than absolute heights. A virtual surface 16 may be constructed from the measured heights, with a tolerance level 17 employed based on the virtual surface. In use, a height sensor 10 measures the relative heights of at least three locations. The invention is particularly suited to measurement of tooling components within a printing machine, such as tooling pins 14, allowing components 14b that are out of tolerance to be identified.
