A professional who tends plasma equipment that dry etches unprotected copper from substrate boards or panels to form circuit patterns on printed circuit boards (PCB's). Respnsibilities include:

• Hangs boards or panels on racks in plasma tank and locks door.
• Adjusts controls, according to process specifications, to set time, wattage, and percentage of oxygen and nitrogen gases in plasma tank.
• Pushes button to activate equipment that automatically plasma-etches excess copper from boards or panels to form circuit pattern.
• Removes boards or panels after processing and inspects boards for completeness of etching process, using microscope.
• May tend computer-controlled plasma etch equipment that automatically computes and adjusts control settings for time, wattage, and gas content based on data entered, such as quantity of boards and lot number.
