Can electronics be damaged by smoke?

If it was my equipment, I would:

a) file an insurance claim.

b) disassemble the unit. Place the circuit board in an ultrasonic cleaner with some 99.9% pure isopropyl alcohol, and run it for a couple hours, changing the alcohol as needed.

c) allow to dry, and reassemble.

I would also be careful to inspect the device for components that might be disolved by alcohol, and remove them first.

Any optical components may need other cleaning methods instead.

I don't recommend this (as a matter of avoiding liability) - it's just what I would do.

Smoke Damage To Electronics

Some do and some don't. If your survey equipments contain lens,ultrared sensor or screen display,dark layer of smoke could affect its performance. Soap water can remove this smoke layer but it requires a good hand and knowledge to clean it without adding more damages by the soap water.

By the ways, fire insurance cover all this kind of damages called "smoke damage". Why bother it ??

yes, the smoke could have gotten inside and laid down a conductive layer of soot.

How to clean depends exactly on the assembly. Best is to contact the manufacturer(s). They will probably want you to return them.

You would not have the facilities for testing, that takes special equipment and experience.

Soot is mostly carbon, which is a conductor of electricity, so it could short out printed circuit boards if left in place. For equipment that expensive and valuable, you should track down a professional and have them clean it.

Good luck.
