PCB solder-in buss bar.
PCB solder-in buss bar.
(OP)
I have to plumb ~30A across a PCB. The trace widths are crippling!
A while ago I saw bus bar you could drop onto a board. It was tinned copper with pins every half inch or so. It was a standard product.
Now that I actually need some, an hour of googling has not produced it. It has produced, countless board houses and machine shops that will make you custom buss for a small fortune...
Anybody got a link or name or alternative?

Custom bus bar is used by some - 1/16" stamped tinned copper.
Also seen is 16 to 14 gauge round tinned solid wire shaped (possibly by hand or simple jig) and soldered along its length directly to a trace to 'up' the current of the trace while leaving the pcb trace only about 125 to 200 mills in width. This sure beats wide traces and paying a premium of plating up to 4 oz copper.
Also seen is keeping heavy gauge wire leads on a transformer (while low current pins remain as thru-hole) and routing the heavy leads to where they're needed.
If you need a buss-bar, I sure you could get some K&S hobby copper and use a nibbling tool on it. From there you could try one of the photo etch or laser etch companies to make low volumes.

I'll probably be going with soldered-in wire.
With soldered-in wire the possibility of a single-sided board actually becomes possible.
That means I could run off a proto with my CNC router.
