Inventor: TANI OKIE
IPC: H05K3/12
Filed: 1996-03-01
Abstract: A screen printing method optimized for screen printing of high density viscous compounds, such as conductive solder, for electronic circuit printing, uses an enclosed type squeegee arrangement. The apparatus utilizes synchronously driven components A-D which by their motion further serve to pump printing material to a printing chamber 6. The viscous printing material is supplied to the chamber 6 form a container 4 and agitator rods D' are rotated within the chamber by a motor DM. An actuator E moves a squeegee blade holder 7, and an inlet 14 allows, eg, nitrogen to be introduced into the chamber. Various squeegee arrangements are disclosed in which squeegees of varying thicknesses are individually controlled for effecting mixed pitch printing operations. Further, movable plate members can be disposed between the printing blades for effecting cleaning, agitating of printing material as well as selectively being enabled to act as printing blades and for supplying printing material from a chamber within the enclosed squeegee structure to each of the parallel plates. Further, another configuration provides a convex blade portion formed of shape memory alloy or the like which may be retracted to allow a narrow gauge blade portion to effect mufti-pitch printing.
