Antminer Board Cleaning -Anyone had results with an Ultrasonic Cleaner?

[BBitcoin92]

Hi All

I mainly use S9/i's due to price and replacement of hash boards being relatively cheap.

I have had some i put in a pile to sell as they do not work or bring a whole S9 down (constant restarting etc), BUT then i have gone to use them weeks or months later and they are fine??

The ONLY thing i have done is cleaned them with a stiff  brush and them blasted them with contact cleaner.

I'm wondering if anyone has had any success with using an Ultrasonic Cleaner and the relevant fluid?

This 6.5l seems to accommodate a whole hash board plus i suspect the fluid would last a long time if you clean the boards as i explained above.

Anyone got any views/opinions on this?

Thanks

I would go cleaning with canned pressurised air and isopropyl alcohol.

dont use ultrasonic as the vibrations may remove some of the parts that are on board.
we have it at work (smaller scale) but never use it for this reason
second this one on ebay is way too cheep
maybe cant do the work
we have one with just 350ml bath and costs around 10times that price.

You can use dish washer to clean the boards and dry it under the sun.

Is this a joke using a dishwasher to clean boards?

Surely water would cause damage?

Are you using a washer tablet as well??

I've ordered some iso alc 99.9% in a sprayer, only sprayair i can get is in a can does not last long.

Cheers

Not a joke. In general, clean water will NOT harm a miner - or for that matter most other electronic devices: PROVIDED THEY ARE ALLOWED TO THOROUGHLY DRY OUT BEFORE APPLYING POWER AND TURNING THEM ON. Water mixed with other cleaners is used in many areas of electronic device manufacturing. Using soap is fine as well but the concern there is that the boards must be very well rinsed off to remove any remaining traces of it. A final rinse with IPA to help drive out moisture before drying would be a good idea as well.

Yeah but steer clear of using any dishwasher designed detergents and finishing agents ...
A lot of them are pretty nasty on metal over time, so even one wash with them could precipitate later damage and failure.

Cheers guys, i'm about to put x3cards in my dishwasher (no detergent/plain water which is soft in my area as well).

I'll leave them dry on a radiator (we have them in the UK...lol).

Then i will spray them with IPA, it's just in a normal manual sprayer.

I also have cans of carb/brake cleaner is in pressurised cans with straw nozzle ends, this stuff also evaporates, has anyone tried that?

Thanks

Highly recommend a rechargeable or plugin Compressed Air Duster.

Then you don't have to buy/store multiple canisters of compressed air. This was a great change for me in my normal device maintenance.

I cleaned the hashboards with isopropyl alcohol and compressed air, and after installing them in the mine, paradoxically, one of them stopped working.
Uncleaned went and cleaned does not go.
I let the hashands dry thoroughly.
How is it possible?

Bad cable connection?

no ... the cables are fine, so i don't know what could have happened.

ESD damage then, maybe?

Did you work with ESD precautions?
