Dear all,
Hoping for ideas / suggestions for unclogging metallic fluid / paste dispense nozzles.
Currently we have a metallic dispense nozzle clogged with silver conductive adhesive.
We have tried using an ultrasonic bath with both fixed and pulsed modes in acetone, along with use of micro wire brushes (smaller diameter versions on order).
Thank you in advance,
Jules
Hello Jules,
May I ask what type of silver paste this is?
There was a similar thread on reddit a while ago:
https://www.reddit.com/r/Physics/comments/1d3ex9u/are_there_any_electrically_conductive_greases_for/
Where the poster was seeking a way to dissolve dried silver-rich pastes.
In short, have you tried hot acetone baths with / without ultrasound agitation?
If that doesn't work, super-critical carbon dioxide is the only thing left up my metaphorical sleeve.
Best of luck!
