Wait, does that mean we need to move it back to a science category? Or do you think a trip back to the watercooler would be inevitable?
I think it’s fine here till some actual science has occurred
i’m still a LONG ways away from the science part of the program.
I didn’t catch faults on this one before it blew. just a couple strange cutout incidents before it smoked itself.
the DRV faults are on another one I just pulled because I feared the DRV faults. I should have given it to you for inspection.
what should I see here? I see bridged pins in the lower right. si that normal?
top row looks all brown and yuck.
black case of chip looks textured like cooked?
and again what should I see here?
looks like fuckery with the case off
and fuckery with the case partially on.
YUP bridged DRV chip pins… when i first tested this one it threw DRV faults…
sciencing up replacing the FET “Source” pads that were blew the fack up… and digging out the “Gate” pad trace…
oooh. that new silver pad is you replaced the blown garbage on the PCB?
that’s freaking cool. DRV (FET) Wizard in training.
copper foil
don’t know… there’s lots of weird unexplainable oddities on your FOCBOX, remember the weird displaced phase wire?
that’s yours… I’m sciencing on @Scepterr 's PCB… as his actually has a good DRV chip and hopefully needs only one directFET replaced… I only just noticed your bridged DVR pins when I was looking at popping yours off …
this focbox came from Lacroix and lived in a prototipo it’s whole life.
and yet…
weirdness occurred
heh. yep. basically my point.
i don’t understand those bridged drv pins… seems like that would have to fuck things over??
weird. that seems like you’d just do that on the board?
or do they need current and it’s easier to handle in a bridge?
yeah… your/s right… i really should have a schematic if i intend to science… I was basing my thoughts on two other similar PCB boards i had…
yup…
…but if you look really closely into the pix… on this particular version… it does appear quite convincingly that that pads are designed to be bridged…
thanks brother for your sanity check!!!
