Job Description:

• 1) Tends equipment that strips photoresist film and etches layers of copper laminate from exposed surface of printed circuit board panels leaving unexposed areas to form conductive circuitry pattern: Reads process specifications and adjusts equipment controls to regulate conveyor speed, spray intensity, and solution strengths and temperatures.

• 2) Positions copper panels coated with photoresist on conveyor that carries panels through series of processing units, such as sprayers, rinsers, scrubbers, and dryers.

• 3) Starts and monitors equipment that chemically strips photoresist and excess copper from exposed areas of PCB panels leaving unexposed copper to form circuitry pattern.

• 4) Observes equipment operation, gauges, and meters to detect malfunctions or variance from specifications.

• 5) Visually examines sample boards during and after processing for conformance to specifications.

• 6) Notifies supervisor of equipment malfunction or substandard etching quality.

• 7) Reroutes panels through processing units to complete stripping or etching process.

• 8) May periodically change or adjust chemicals and solutions.

• 9) May test acid solution, using pH meter.

• 10) May manually immerse panels into processing tanks.

• 11) May inspect circuitry pattern on panels, using microscope.

• 12) May be identified according to process involved and be designated Etcher, Printed Circuit Boards; Stripper, Printed Circuit Boards.
