Pick a niche i.e. Fiber cable splice or BGA replacement service. There are tons on EMS providers and with very cut throat prices. I gaurentee you if you had a BGA rework station and an xray - and offered services in this area you will make a killing

I'm not sure why anyone would pay extra for FG (fine grain) stencils. I've run studies comparing traditional YAG laser, fiber laser, and E-form stencils with regular stainless, FG, and nickel foils. YAG is the worse and should only be used for pret
