PCB support
-
Hi everyone ^^
just a little question about PCB supportβ¦
i'm at the end of a project, but i'm a little stuck on the fixation part of the boardβ¦
in the first version, i have just putt two hole with pretty random diameter, but for the actual version (i hope final version), i want to chose the most smaller diameter, but with possibility of attachement in a plastic box
so two questions :
-what kind of fixation do you usually use, and where can i find them?
-what diameter could i use on the pcb for the fixation? (2mm start to be tricky for routing with just two hole on the board, 4mm was⦠maybe not impossible, but really close to that!)Thanks

Fixing a board in a box ... it depends, bit I try to use 2mm holes because if have small screws of that diameter.
I have also used double sided 3m tape which sticks quite well to a pcb and a plastic housing. No holes needed then.
-
well, 2mm works fine (no routing pb), but i keep in mind the double sided tape idea
Thanks for the tips ^^

Hot glue fixates almost everything, including pcb's.
Or like eevblog calls it - hot-snot

like guys said
on my side now I try to use holes for M3 screws, but M2 is nice too

Thanks for answers
i think i should find some m2 motherboard spacers and screws in the bottom of a cardboard box, and if i need a box, double sided tape or hot glue ^^

There are standards for PCB hole sizes. You can find Eagle parts for M2, M2.5, M3 drill holes with tight and loose clearance in my Eagle parts library. I created the parts from this blog page.
