Hi all,
I am trying to manufacturer a PCBA which is required to operate on a nasty environment.
Application: downhole OIL and gas
temp:-50C to 125C, lots of shock/vibration and humidity.
the PCB is a flexible PCB, so I can not pot it. I also have bunch of PTH components. I used MG422B, two times spray, and let it dry on the room temperature, still there is no coating on the sharp edges of PTHs.
any suggestion on better material or better technique for the confromal coating. Thank you so much in advance.
