Abstract

A print head assembly (119) for printing a print medium (PM) onto a workpiece (W) through a printing screen (105) which includes a screen element having a pattern of printing apertures therein, the assembly comprising: first and second carriages (141) which are in use movably supported on respective ones of first and second guides (117); and first and second print head units (143, 145) which are mounted in adjacent, parallel relation to and between the carriages, wherein the print head units each comprise first and second print head actuators which are mounted on respective ones of the carriages, and a support member (151) which extends between the print head actuators, such as to be movable vertically thereby, and in use supports a printing element.

Description

technical field [0001] The present invention relates to a printhead assembly for printing a printing medium, such as liquid ink or solder paste, through a printing screen onto workpieces, including fine or delicate substrates, such as for solar or fuel cell applications, and the printing wire The screen includes a pattern of printing holes corresponding to the pattern of deposits to be printed on the workpiece; the invention also relates to a screen printing system and a screen printing method incorporating the printhead assembly. Background technique [0002] A wide variety of screen printing systems and print heads have been developed today for printing printing media onto workpieces. [0003] figure 1 and Figure 2 shows a typical screen printing system utilizing a print head in the form of a squeegee mechanism. [0004] The screen printing system comprises a rigid support frame 3 supporting a printing screen 5; a pair of parallel spaced apart linear bearings 7, 7 mounte...
