Trouble Posting to Microchip forum
Posted: Wed Sep 02, 2020 8:49 amHi People
I'm desperately reaching out, it has been years since I posted on the Microchip forums and I finally had something to say where I wanted to help a fellow member.
Maybe one of you can post this and help him out. I have tried PMs and post publicly but have hit a brick wall it would seem.
bluemagoo92 Re: My PCB for my dspic33 is shorted between power and ground, and I don't know how
I've been avidly following this thread. Everyday I login just to check if someone has found the murder in this little murder mystery. I've attempted posting to the forum on a number of occasions and eventually give up fighting the forums software password entry system. Anyway, enough of my problems.
I was curious to see images of your top and bottom board design at first but I think I may have a little information about the murderer, was it the man with the knife? or the professor with the candle stick?
I think it may be the conductive flux residue.
Why do I think that.
Reading two of the one star reviews on the flux you posted.
Jeffrey B. 1.0 out of 5 stars Not safe for PCB work
'''It says it's good for PCB work, but it's not. It can cause a fire. If you have fine pitch parts and the power and ground are close together it will make a residue and continue to eat away at the solder. eventually it shorts the pin together. I had a nice fire with that the other day'''
And
Hung M Vuu 1.0 out of 5 stars It is conductive...
'''It is conductive when it is dried up. Enough said, flux should not be conductive.'''
I am actually disappointed now as I will have to find some other thread to follow.
Good luck.
Don't give up.
