It may make sense to charge by aperture, but it means in some
organizations that you'd have to get a quote for each stencil you buy -
increasing the time it takes to get your stencil in the door.
I also wonder what the cost breakdown is for making a stencil - cost of
materials, mounting it in the frames, vs the run time on the laser...
Anyway, the original question - laser vs electroform - we pay about 2x
for an electroformed stencil. We've only used a couple - where we have
some strange parts and need to put more solder in a couple areas but not
in adjacent areas.

Geert,
Logic has little to do with the market conditions. I agree that it makes
sense to price laser cutting by aperture count. However, the reality in
the US is that we have to compete on a fixed price basis. So... yes, a
500 aperture count stencil will be the same price as a 5,000 aperture
count stencil.

Laser cutting of a stencil is a process of which the duration depends on
the
number of apertures to be drilled (one after the other). Logically, the
cost of producing a laser cut stencil increases with the number of
apertures. This is not the case for an electroformed stencil.
Do you really pay the same price for a 500 vs. a 5000 aperture lasercut
stencil in the US? I notice al lot of different price differences being
quoted between LC and EF.
To give an idea from my experience, a 10000-15000 aperture laser cut
stencil
could cost as much as an electroformed stencil. A higher number of
apertures
would make the laser cut more expensive than the EF.
