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

Is this a new process or are you experiencing a change in results from an already established process? We have KISS Slective Soldering (2 machines)and we do not have these issues, but we are not doing NC either, we are fully aqueous, using Nitrogen

blow holes and via holes are almost always caused by moisture and in PTH they could be moisture and improper drilled holes. If you are seeing solder balls next to the parts than I would say you have a reflow profile problem. Are you using any kind of

We had a similar problem with foam in our inline cleaner (TD). The problem were the solder paste flux residues. Boards went straight from SMT to Wave process and then washed. Anyway we changed the solder paste and problem solved. Are you using saponi

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

using fids instead of pads I agree would be more accurate. However if the board and stencil do not register then nothing will align. We have started to fo many stencil to board matching due to board distortion either before or during production. We a
