Abstract

This apparatus fabricates resistors and conductive members by extruding metal paste, inks and decor enamels through a mask onto the surface of a substrate. The apparatus requires relatively few moving parts as compared with silk screening techniques. Resistors and conductors are readily reproducible in any desired configuration, when fabricated by the apparatus.

Extrusion Printing Apparatus

This apparatus fabricates resistors and conductive members by extruding metal paste, inks and decor enamels through a mask onto the surface of a substrate. The apparatus requires relatively few moving parts as compared with silk screening techniques. Resistors and conductors are readily reproducible in any desired configuration, when fabricated by the apparatus.

Cylinder 20 is suspended in fixture 22. At one end of cylinder 20, removable cap 26 includes extrusion mask 27 through which a paste is applied to the surface of a substrate, not shown, positioned on movable platen 50. At the other end of cylinder 20, air hose 32 is connected through removable cap 34 fastened to cylinder 20. The air pressure is regulated by valve 36 and gauge 38, which are manually controlled. Timing device 40 in conjunction with an electromagnetically operated air valve 42 controls the application of air pressure to cylinder 20. Platen 50 is positioned beneath cylinder 20 and linkage brings platen 50 and the substrate beneath and firmly against mask 27.

To deposit a conductive or resistor paste, ink and decor enamel, cylinder 20 is filled with the material which is to be printed on a substrate. The viscosity of the material is adjusted by an inert vehicle to aid passage through mask 27. In the absence of air pressure, surface tension of the material is sufficient to prevent leakage through mask 27. A timing interval is set up on the timer and the manually con...
