Who makes it
Today 5 steps run here, 13 by partners and 66 are bought. The plan runs 10 here, 18 by partners and buys 56.
Machines here: assembly bench, spring coiler, test bench, tube bender. Partner capabilities wanted: chip packaging, die casting, injection moulding, metal stamping, open pdk foundry, pcb assembly, pcb fab. Standard chains use typical published yields and loadings, rounded; none is measured on a line this network runs.
