ENIAC, 0.040" equates to 1mm, not 0.1mm. 0.040" is the IPC minimum recommended fiducial size and when we started putting fiducials on our boards I assumed that all equipment manufacturers should be able to automatically spot that size. Since then I'v

We use Hilman rollers (Hilmanrollers-mf.com) and/or pallet jacks. Printers and smaller P&P machines can be moved with pallet jacks. Large machines such as chipshooters require rollers and man power but you'd be amazed what you can push around on Hi

The stencil doesn't seem to match the pcb. On the pcb there seems to be pads that are wider than others whereas the openings in the stencil seems to be uniform. As Phil mentioned, make sure the gerbers match the stencil. As for no fiducials, that sho
