Diagram in symbolic form of a functional electronic circuit.
A substrate that has been scribed with a thin cut at the break-lines.
A network of metal or fabric strands, mounted on a frame, and upon which the film circuit patterns and configurations are superimposed by photographic means.
The laying down of a circuit pattern on a substrate using the silk screening technique.
The process whereby the desired film circuit patterns are transferred to the surface of the substrate by forcing material through the open areas of a screen using the wiping action of a soft squeegee.
A trim cut in a film resistor that follows a serpentine or wiggly pattern to effectively increase the resistor length and increase resistance.
The electrical resistance of a thin sheet of a material with uniform thickness as measured across opposite sides of a unit square pattern. Expressed in ohms/square.
A screen of a closely woven silk mesh stretched over a frame and used to hold an emulsion outlining a circuit pattern and used in screen printing of film circuits. Used generically to describe any screen (stainless-steel or nylon) used for screen printing.
A dielectric composition screened across a conductor to limit molten solder from spreading further onto solderable conductors.
The ability of a conductor to be wetted by solder and form a strong bond with the solder.
The process of joining metals by fusion and solidification of an adherent alloy having a melting point below about 400 degrees F.
The part of a screen printer that pushes the composition across the screen and through the mesh onto the substrate.
Stainless Steel Screen
A stainless steel mesh screen stretched across a frame and used to support a circuit pattern defined by an emulsion bonded to the mesh.
Step and Repeat
A process wherein the conductor or resistor pattern is repeated many times in evenly spaced rows onto a single film or substrate.
