I’m looking to make some shields, but I don’t know what a good thickness is for PCBs.
I want it to be as thin as possible (to make for easier cutting and drilling), but not so thin that it will bend/break.
What are some thicknesses that you people have had success with?
Well if its a shield it probably won’t be moving much, so thinner would probably be okay. Unless the shield will be often removed and replaced.
Well, I was looking at very thin PCBs (like the thickness of 3 sheets of paper), and that was too thin according to most people.
Do you have any specific recommendations?
find someone with a bandsaw ;D
My neighbor has a bandsaw, but I read that it eats through the blades very quickly, and that all the FR4 dust jams the blade and gets in the lungs…
I do not like the .032" I got from a surplus web site. It flexes way too much, breaking solder joints, etc. The copper is thin, too, but that’s a separate issue.
I prefer .062" minimum.
Fiberglass (FR4, etc) is rough on tooling, but you’re not cutting all that much when trimming a few PCBs (I’m assuming you’re not going into business or making production level runs). I use a cheap carbide tipped blade (same one I use for rough 2x4s, pressure treated lumber, etc).
I saw some .06 on eBay cheap, so I may go ahead and grab that :).
