Job Description:

• 1) Performs any combination of following tasks to print and etch conductive patterns on copper-faced plastic, fiberglass, or epoxy board to fabricate printed circuit boards: Cuts board to designated size, using sheet metal shears, following written or verbal instructions.

• 2) Sands board and either places board in vapor degreaser or immerses board in chemical solution to clean and remove oxides and other contaminants.

• 3) Sprays or brushes light-sensitive enamel on copper surface and places board in whirler machine to spread enamel evenly, or tends machine that flows light-sensitive resist over board.

• 4) Laminates light-sensitive dry film to board, using heat and pressure equipment.

• 5) Exposes board and circuit negative to light in contact printer for specified period of time to transfer image of circuit to board.

• 6) Immerses exposed board in solution to develop acid-resistant circuit pattern on surface.

• 7) Compares board to sample to verify development of pattern.

• 8) Applies acid resist over sections of pattern not developed, using brush.

• 9) Immerses board in acid or tends etching machine to etch conductive pattern on copper surface.

• 10) Immerses board in solution to dissolve enamel.

• 11) Drills holes in board, using drill press, following work sample, drawing, and diagrams.

• 12) Installs hardware, such as brackets, eyelets, and terminals, using eyelet machine and hand arbors.

• 13) Reduces circuit artwork prior to printing onto board, using reduction camera.

• 14) Prints conductive pattern onto board, using silk screen printing device.

• 15) Fabricates PCB used as prototype of production model.
