I have a requirement similar to thread820-286770. I'm designing a PCB which drives 64 solenoids. Each can take up to 0.9A at 18V, and half of them can be on at once giving a peak current of 28.8A. I need a way of carrying this current which doesn't rely on the board tracks. I am imagining a laser cut or chemically etched copper busbar say 0.5 to 1mm thick, with "pins" formed every 20mm or so which could be soldered into holes on the PCB. I haven't been able to find anything off-the-shelf to do this. I've found one or two people who would make them for me, but in small quantities the price is excessive (about £16 per busbar for 12 off).
Does anyone know of anything that would do this job that's available off-the-shelf (and that's less labour intensive and neater than just soldering thick tinned copper wire to the power and ground tracks on the PCB)?
Or does anyone know of a cheap process or supplier for custom copper sheet products like this?
Or can you think of a better way of solving this problem?
Many thanks - Rowan
