I need to get a piece of stiff material cut and drilled for a project I'm working on. It has the following requirements:
- 1.6mm thick
- should be stiff (similar to PCB material, aluminum, fiberglass)
- about 12" x 3"
- 6 holes need to be drilled (all around 5mm in diameter)
- will be making ~500 of these plates
- material type is not important - just needs to be about as stiff as PCB material/fiberglass
- conductivity doesn't matter - metal or non-metal is fine - my PCB will have plastic board supports spacing it off of the mounting surface.
I'm trying to figure out the best material that will yield the best pricing were I to outsource this to a machine shop or manufacturer of some kind. In other words, what combination of material and machining process will cost the lowest. I was looking at having a PCB manufacturer use PCB material (because this will be the mounting plate for my PCB and they'd already have all the tooling), but I'm open to use fiberglass, metal, plastic, or any other material. I was hoping that someone here might have done projects with various machine shops or manufacturers and be able to provide some recommendations as to the best materials and processes to use.
Just to provide a few more details - I am manufacturing a PCB and I need a mounting plate on which to mount DIN rail clips. So, the PCB will have board supports (which allow for a loose-ish fit) which hold it to a mounting plate (of some material type), and the mounting plate will have DIN rail clips attached to it. The reason for the plate is to provide something to which the DIN rail clips can mount to. I do not want the PCB directly attached to DIN rail clips because I don't want twisting forces applied to the PCB during DIN rail mounting/removal.
