Busbar FAI and PPAP: what belongs in the first article pack
A busbar can pass a dimensional layout and still fail at the joint. Here is the first article pack that proves the part, the material and the current path together.

Epoxy powder coating for busbars: thickness, coverage and masking
A coated bar is an insulation component, not a painted one. The drawing has to say where the film goes, how thick it is and which faces stay bare.

Die wear and tool life: how volume affects unit price
Tooling is a fixed cost, wear is a variable one. The volume you commit decides which of them dominates the piece price, and when a new die is cheaper than an old one.

Go from reading to checking
The guides are built around the same questions as the free tools. Size a busbar, check an ISO 2768 callout, build a first article report or compare landed cost.
