Commercial Most commercial users will gain satisfactory performance from this coating by curing for two
hours at 90°C after the two-hour ambient cure. This will give limited resistance to solvents.
Military If the assemblies are to be used under conditions of high temperature or be exposed to
extremes of thermal cycling, the coating should be cured for 12 hours at ambient followed by 24
hours at 90°C. For maximum solvent resistance cure at 2 hours at ambient following by 24
hours @ 120°C. This curing schedule will give resistance to the more aggressive solvents.
It is recommended that the coating be thoroughly cured on circuits, which have design areas of very high
impedance that require adjustment after application.
Inspection
DCA contains a UV trace, which allows inspection of the PCB after coating to ensure complete and even
coverage; the stronger the reflected UV light, the thicker the coating layer is. UV light in the region of 375nm
should be used for inspection.
