Conformal Coating

[cunomar]

Before i screw my laptop back together I'm wondering if i could spry everything with conformal coating to protect against the next spill .

Might i kill it ?

If the coating is conductive, absolutely. Overheating would also be a major concern.

Conformal coatings are designed to protect printed circuit boards from environmental damage, so I wouldn't worry about them being conductive. I use them on electronic devices I keep outside, like the stereo amplifier in my gazebo. The problem I see is keeping the coating away from connectors, PCB ground rings around mounting screw holes, heat transfer surfaces, etc.

You mentioned "next spill". What happened during the last one?

Can't even remember now , killed my keyboard and wouldn't power on i think but when i seen a full used palmrest it was called with keyboard , touchpad on button etc all still attached at a reasonable price i took a gamble that manufacturers reuse what they can for different models and it fit . It just bugs me that they charge stupid money for the internals then wrap it all in tuppence worth of brittle plastic .

If you need any laptop to be lighter in weight then you should be sentenced to wear heavy led handcuffs for a year 🤣

Why not just put cling-film over the keyboard?
