For some additional info on what we are doing..

We are currently having to mask off on a typical board, 4 x 4.5mm hole
with large lands, 1x3mm hole with large land, 3x1.5mm hole & 4 pads for
LED's.
All but the LED's are too big for screened on peelable resist(drips
through), and we cannot apply that to the SMT side.

Once the board has been placed, reflowed & ATE tested, the above is done
to both sides (takes ages).
Then they are put to one side for a few hours for the masking to cure.
Then dipped & hung in a cabinet to cure overnight.
Then the masking has to be peeled of each individual pad (taking ages
again).

There are 12 boards per panel & done in batches of about 2000.

And that's only one product, we have lots more like it.

As you can see this adds a considerable amount of time to the production
times for this product.
If we could automate this better to reduce the time it takes to make
these products, everyone would be far happier.
