Industrial circuit boards commonly operate in harsh environments. Operating cycles
create temperature fluctuations where the board repeatedly heats and cools. Over time
this stress on the circuit board could result in cracks or open connections. Exposure to
airborne contaminants such as work piece debris or moisture can build on the circuit
board and cause shorts between conductors, resulting in undesired operation or complete
circuit board failure.
When a faulty circuit board is suspected, it is important to remember not only to
troubleshoot the circuit board, but also the related components in the system that the
circuit board controls. Verify the integrity of the incoming power and any components at
the output of the circuit board that could compromise the reinstallation of a repaired,
refurbished board. For example, if there is a short on the output of a circuit board that is
not remediated prior to re-installation you could cause a repeat of the initial failure.
