The price of any kind of tag board is gone insane, there big clumsy things and they break easily , turret board and turrets , stupid money
Ive been looking for a cost effective way to hardwire tube gear ,especially mics , and I think I found it .
M2.2 solder tags , M2 truss or countersunk semi hollow rivet, hollow M2 rivet , M2.2 washer , suitable punch and die set and some practice .
Circular 3mm thick PTFE washers/spacers/gaskets are available in several standard sizes relating to pipe diameter , with what ever centre hole cut out you require for next to nothing
It makes a perfect board material for tube mics. you drill punch and place the mountings tags or vias as dictated by the pitch/ mounting style of the components you've chosen , its all do-able with hand tools .
I'll can add illustrations if anyone is lost in translation .
My question is about metalurgy
what can I mix
plain brass , nickel plated brass, zinc plated steel ,carbon steel,stainless etc , if I want a reliable electrical connection between my rivet/tag/ solder do I need the same metal/plating ?
I took a closer look at some of the B&K head amp circuitry , many of the larger components have a through hole in the pcb made with tiny punched rivet , other extra high impedence nodes have PTFE insulated standoffs , ultimately your not relying on a copper strip glued to FRP with a blob of solder to support the weight of the component under extreme vibration , its anchored ,well and truely rocket proof , service or swap out a component , even the ham fisted wont fry the board , thats the kind of engineering you want .
