PCB assembly
Control board assembly
A populated board, quoted per unit at 500. Stencil and test fixture are the one-off; freight is trivial and duty is zero, so this is the closest to a quotation that means what it says.

Notes
Duty is zero on this line and freight is $1.80 a unit, so the gap between the quoted $28.90 and the landed $42.64 is almost entirely tooling and scrap. It is the narrowest gap on this shelf at 1.48 times.
At ten times the break quantity, 1,740 boards, the landed price is $30.76 against a $26.35 tier rate. Scrap at 2.5% is doing most of the remaining work, and on a populated board scrap is component cost, not laminate cost.
