soo. i have this screen pcb and theres this series of pins that i dont really need (hope i dont need them)

misterjthe5


misterjthe5

i was wondering if it would be ok to shave them off

misterjthe5

they seem to be connected to a sd card port?

misterjthe5

ok as in like the screen would work either way

oops.se

Without the source file for the PCB it is impossible to answer, so your guess is as good as mine.

oops.se

And Im the cautious guy so I wouldn't do it.

misterjthe5

i can give u the link for the product

misterjthe5

i found the block diagram for it

k9t33n

why do you want to shave it off?

oops.se

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.

misterjthe5

too big

misterjthe5

barely fits

misterjthe5

i need to shave

misterjthe5

justtttt abit..

k9t33n

I mean barely means it does but okay

misterjthe5

oh it dosnt fit at all

misterjthe5

bc its too perfect

misterjthe5

i need to shave it off abit.

k9t33n

can you shave just the slight outline though?

misterjthe5

yes

k9t33n

like before any of the actual wiring. then your fine

misterjthe5

i understand. so ill be able to those extra parts on the side

misterjthe5

that will help me significantly

misterjthe5

and if i wont be able to fit it in ill just shave off the sides of my shell

k9t33n

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

misterjthe5

that i intend to put the screen in

k9t33n

exactly

misterjthe5

lovely

misterjthe5

thanks

k9t33n

glad to help

k9t33n

unless <@796000224690307072> has any other ideas?

k9t33n

things that I haven't thought about?

k9t33n

nvm he's going to sleep

misterjthe5

also

misterjthe5

how should i shave off the sides

misterjthe5

should i use like a nail file?

misterjthe5

im also intending to shave off a plastic case

oops.se

I use sandpaper or a hacksaw with a 32TPI blade

k9t33n

sandpaper? also the brackets I said are quite important

oops.se

But think of it like this is a 50/50 % chance to succeed

k9t33n

you need to know it's not a multilayered pcb, your probs fine but just to make sure

k9t33n

what are you saying is the effect of failure? its broken or just won't fit?

oops.se

The brakets aroundd the LCD?

k9t33n

no the brackets in this

oops.se

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

k9t33n

yes be careful of that

k9t33n

don't sand it anymore then you need to

oops.se

Im off, cya

k9t33n
