PCB holder 2
As promised this is update to last post about our PCB holders. Technical difficulties It turns out that if I want tapped hole every 10mm that's a lot of tapping. Additionally tapping steel is quite hard, especially with such small tap. Most companies decided that they don't want to do such job, one that agreed is research institution so I guess they're used to nontrivial requirements. After some negotiations we got price of almost 5k euro for 300x300mm sheet. That's a bit too much for this project. Required changes My changing steel to aluminum and moving holes onto 15x15 grid we considerably reduced required engineering time. After initial testing it turned out that 15x15 hole spacing is more than sufficient, but swapping to aluminum means magnetic mounts are no longer an option. I guess it's low price to pay to reduce manufacturing cost to 740 euros. plates when they first arrived in our lab Designed mounts We designed few mounts for plates to mount things on t
