You deserve a well-earned break! When you come back, give your work a
thorough "QC" quality-control check before moving on to the testing and
alignment section.

TESTING AND ALIGNMENT

PC Board Inspection: Before applying power to your kit, give it a thorough
QC (quality control) inspection. This will help you find inadvertent assembly
errors that might prevent the radio from working or cause damage to sensitive
parts. Follow this procedure:
! Compare parts locations against the parts-placement diagram. Was each
part installed where it is supposed to be? Was the correct value used? Start
at one side of the board and work your way across in an organized pattern.
! Inspect the solder side of the board for cold-solder joins and solder bridges
between tracks or pads. Use a magnifying glass to obtain a clear view of the
track area. If you suspect a solder bridge, hold the board in front of a bright
light for a better view. All joints should be smooth and shiny, indicating
good solder wetting and flow.
