Help trimming a PCB
March 15, 2024, 21:07
soo. i have this screen pcb and theres this series of pins that i dont really need
(hope i dont need them)
i was wondering if it would be ok to shave them off
they seem to be connected to a sd card port?
ok as in like the screen would work either way
Without the source file for the PCB it is impossible to answer, so your guess is as good as mine.
And Im the cautious guy so I wouldn't do it.
i can give u the link for the product
i found the block diagram for it
why do you want to shave it off?
That doesn't help as it has no information about the PCB. Gerber files or the original EDA files is the one that can reveal any issues with modifying the PCB.
too big
barely fits
i need to shave
justtttt abit..
I mean barely means it does but okay
oh it dosnt fit at all
bc its too perfect
i need to shave it off abit.
can you shave just the slight outline though?
yes
like before any of the actual wiring. then your fine
i understand. so ill be able to those extra parts on the side
that will help me significantly
and if i wont be able to fit it in ill just shave off the sides of my shell
trim it down all the way around without coming across any copper (also make sure it's not multilayered so theirs not copper you cant see) then it's a guaranteed way to make it fit
that i intend to put the screen in
exactly
lovely
thanks
glad to help
unless <@796000224690307072> has any other ideas?
things that I haven't thought about?
nvm he's going to sleep
also
how should i shave off the sides
should i use like a nail file?
im also intending to shave off a plastic case
I use sandpaper or a hacksaw with a 32TPI blade
sandpaper? also the brackets I said are quite important
But think of it like this is a 50/50 % chance to succeed
you need to know it's not a multilayered pcb, your probs fine but just to make sure
what are you saying is the effect of failure? its broken or just won't fit?
The brakets aroundd the LCD?
no the brackets in this
There is a multi connector between the PCB and the LCD and if that gets misaligned you have a dud display. So DON'T touch the frame for the LCD
yes be careful of that
don't sand it anymore then you need to
Im off, cya
