Hi there - I'm working on the layout of a PCB that will be carrying ~30A or so. I'm running some parallel traces to increase the current carrying capacity of the PCB. I would like these traces to be connected with vias. My question is this: Is it better to have lots of really small vias, or just a few really large vias? Also, should these traces be connected just at either end of the trace, or should they have vias connecting them throughout the trace?
I wouldn't put vias "here and there along the length" as the hole reduces the width of the trace. Along the line of the test point idea, you can use copper rivets. There are hobbiest size rivets that work nicely.
Yes it does in the AC case. That was where I suggested it.
I don't use those either. I only use things that can be inspected. I also think you are wrong in suggesting it is no worse than the swage terminals. Remember that those terminals were designed for the purpose by people who hopefully knew what they were doing. The rivet is not intended for the job.
