Test and Inspect the Completed Unit
To help ensure maximum quality of all products, it is the responsibility of the assembler to
complete a post assembly inspection prior to sending the unit on to electrical testing and final
inspection. This should help achieve one goal: no unit shall ever be returned from test and
inspection for rework because of a mechanical defect that could have been corrected at the
assembly stage. Remember that things that have already been inspected during assembly may
have been inadvertently damaged during the assembly process. With this in mind, fully inspect
the unit for mechanical defects. Things to look for include:
• Cosmetic damage to any visible surface of the unit. This includes but is not limited to:
defects to the silk-screening – both front and back panel, dents, dings or scratches in all
outer surfaces, smooth even surface color of the front panel, even paint coverage and
texture to the top cover, scratched or fingerprinted lenses, scratches or fingerprints on
buttons, damage to button text or keycaps, and/or visible process marks on knobs and
other plastic parts.
• Proper complete assembly of all parts. This includes but is not limited to: Presence of
all parts, flush full insertion of all screws. Even consistent spacing of knobs, proper
centering of lenses in cutouts, etc.
• Proper mechanical function of all components. This includes re-testing all knobs for
smooth consistent feel, testing all buttons for proper feel.
• Add stickers for inspection, serial number and AC voltage.
If there is any question about the quality of a unit, consult a supervisor for guidance. If the unit
passes assembly inspection, the unit is complete and ready to proceed to electrical testing, final
inspection, pack and ship.
