#qmx Base PCB washability #qmx


 

Hi,

What is the washability of the main PCB?? Naturally, I wouldn't wash the display/encoder boards, but I might like to remove some of the flux I've added in the QMX of Theseus (as I'm now going to call it).? I normally wash my PCB's with technical grade IPA and/or hot water with a soft toothbrush for scrubbing before drying really well, but since I didn't design this PCB, my biggest concerns are the audio jacks.? Anything else I should be concerned with?

Hi Martin,?

I used 91% isopropyl alcohol and a very soft toothbrush. ?I was gentle but did the whole bottom, which I have rarely done in the past. So much cleaner. ?The shack has good magnification so looked it over well. ?My recommendation is go gently, especially on the SMDs and ICs. ?And, I would do it on the next one!

Sounds good, I just cleaned the backside, I didn't really need to immerse the whole thing, but a good scrubbing with an ultra-soft toothbrush leftover from the dentist and 99% IPA did the trick.? The QMX of Theseus lives......!
