If you want a PCB with no conformal coating, go to the junk yard and pull an airbag control module out of just about any car. They put them on the lowest part of the car, floor board usually under the center console, they don't seal the enclosures, and they pray you drive it into high water and short the thing out.That assumes there is no conformal coating on the hard drive already. Likely difficult to find a hard drive without a conformal coating. You need the product to come into contact with the bare copper.
Proper conformal coating compounds are inexpensive abundant and readily available... At considerable risk of appearing trite: If it's worth doing, it's worth doing correctly!OK i know this is really old but Zep makes 3-4 different floor sealers, can someone tell me which one was used?

Right, so if I'm translating correctly you're concerned an airbag might go off. Danger easily mitigated. Disconnect battery (probably no battery anyways in a junkyard) and wait a minute before extracting the control unit. If you're still concerned, have an unwitting bystander remove it.Although cognizant of the jocular intent of your postI'm bound to disclaim the hazards attending said 'extraction' - exponentially so should the vehicle be equipped with 'fragmentation airbags'

Please be advised that certain implementations are capable of deployment up to six weeks following disconnection of external power (external, that is, to the 'module' itself)...Right, so if I'm translating correctly you're concerned an airbag might go off.

You must be blessed with a 'cast iron' conscience and lots and lots of 'karma points'If you're still concerned, have an unwitting bystander remove it
Strantor your correct.The control module it's self is a separate entity from the air bag. Junk yards around here remove the airbags first when a car comes to the yard, letting them sit on shelves, to keep them dry inside for sale to the body shops. this whole "air bags are very dangerous" thing is way overblown. It's spread by people that have never even worked with them. If they are so dangerous on they're own, how come they are sitting around in cardboard boxes on the assembly lines? Or shipped from the manufacturer by common carrier in bulk? Another urban myth spread by people that don't know how things work.If you want a PCB with no conformal coating, go to the junk yard and pull an airbag control module out of just about any car.

I've personally encountered two 'quads' (disabled by airbag deployment while working on their parked and de-energized vehicles) who might dispute with your 'theory'.Another urban myth spread by people that don't know how things work

ETA the two incidents did not involve defective airbags...
How extremely coincidental. Was this just by happen chance or do you work as an OSHA safety auditor? Maybe you were an attorney filing class action lawsuit against Takata?I've personally encountered two 'quads' (disabled by airbag deployment while working on their parked and de-energized vehicles) who might dispute with your 'theory'. [...] ETA the two incidents did not involve defective airbags...
In one case adherence to safety procedures was the finding of the (injured party's) insurance carrier -- in the other case, the court...So, did these quads show you that they actually disconnected the battery or did they simply CLAIM to have disconnected it when they told you the story. It would be worthy of an investigation if it went off more than 10seconds after the disconnect.
It wouldn’t be the first time a foolish person claimed not to be foolish.
Again, I would agree that the benefits outweigh the risks Re: non-defective, properly installed systems...Or staring you in the face every time you get in the car
Nope -- My job is (attempting) to put the victims back together - and, often, without unqualified successHow extremely coincidental. Was this just by happen chance or do you work as an OSHA safety auditor? Maybe you were an attorney filing class action lawsuit against Takata?
Please be advised that the hazard is not limited to defective units -- Deployment of any passive restraint installation while the occupant{s} are not within the 'expected relationship' to the system is potentially deadly (and frequently injurious)... I'm aware of several instances whereon deployment occurred at 'ignition-on' as a result of wet floor carpeting (secondary to leaky windshields, back-flowing a/c condensate, etc...)Takata

No need for apologies! -- For my part, I apologize should my formality have appeared 'condescending'Please accept my apologies.
I accept your warnings about airbags and will drop the topic now, also since it's off-topic anyways.
Ditto!and will drop the topic now
Again you accuse me of trolling. Disagreeing with you is NOT trolling, your name was never even mentioned. You may know what you're an expert on, but don't know what you don't know about. I have removed some where in the area of 75 to 100 air bags from cars in my life. Working at a junk yard owned by a friend and on my own vehicles. They themselves don't just "go off". Static electricity won't set them off. Working on the crash sensors won't set them off if you do one of two things, remove the battery cable(best bet) or just the fuse to the SRS circuit. The Takata problem isn't that they go off by them selves it's that they are made wrong, too powerful. One of the departments where I worked made the wire harnesses for air bags and they had them sitting around with never an incident.@shortbus Trolling and safety are an appalling mix! -- Grind your axe elsewhere, little boy...

And once again your response ignores (i.e. interpolates) my point which being far less the 'shrapnel issue' Re: defective airbags (Takata) than hazards attending inadvertent deployment of any modern passive restraint system...Again you accuse me of trolling.

Failure to actually read your "target's" posts is rather transparent, don't you think? -- Sorry! I'm not buying the 'senility card' - Perhaps you feel feigning/mocking serious impairment is humorous? - I don't!Please be advised that the hazard is not limited to defective units -- Deployment of any passive restraint installation while the occupant{s} are not within the 'expected relationship' to the system is potentially deadly (and frequently injurious)...

As previously stated, certain units remain dangerous (i.e. potentially 'armed') for up to six weeks following removal of external power according to their service literature... Shall we sweep that under the rug in deference to your vast 'empirical experience'?Working on the crash sensors won't set them off if you do one of two things, remove the battery cable(best bet) or just the fuse to the SRS circuit.

Jeeeze... How ever could I have arrived at that notion?Another urban myth spread by people that don't know how things work.
But your behavior parallels that of members that you (and others) have deemed 'trolls' (most especially failing to argue opposing points on their merits, obdurate insistence upon your views sans the least effort at credible support, wandering from topic to topic in search of a 'point of contention' and otherwise playing dumb! -- If you are not trolling then neither was RK -- But then, for all his nonsense, RK was courteous!Again you accuse me of trolling.
Granted! But then, IMNSHO, the most cautious advice is always correct where safety of life and/or limb (i.e. ability) is concerned!I love when people claim "it must be true, a (court/politician) said it is true)". What do those sources have to say about technical truth or reality. Laughable.
This is getting funnier and funnier. A healthcare professional talking about safety. So many accidental deaths are addressed by confidential tribunals and still, nothing improves. I’ve been to your cross-contamination centers (I believe you call them hospitals).Granted!

Touché (to wit: I'll take your word Re: the statistics)This is getting funnier and funnier. A healthcare professional talking about safety. So many accidental deaths are addressed by confidential tribunals and still, nothing improves. I’ve been to your cross-contamination centers (I believe you call them hospitals).

Unfortunately, the third-leading cause of deaths in the US are hidden by doctors, “patient died of infection” is the current procdure - when it should day, “hospital killed him because someone was sloppy”
