Dear Mrs and Mr TechNet,
sorry for putting 'she' first, but that's my bad western grow up...
Now, we go on with our adventure 'the Hunt for the perfect needle', which will make Mr Ford a matte silhouette only in comparison.
a) we are now tuning our own syringe, good design but not so easy to make. Guess we will need a Swiss specialist. For Certina or Swatch, it's a pixel of a cake.
b) Anyone with experience of the new Mass. shop as follows: <www.dltechnology.com> ? They make syringes with .2mils of ID accuracy. What about that!! And they say that they can avoid the disaster causing centric rings that are oftenly caused by the today's way of manufacturing. The DL guys are from Camalot, but started on their own, of some reason.
c) We also look at the new Asymtek syringe 'Dispensejet'. Interesting design with a special heater for making the viscosity constant during operation. The question is if they can manage 80 and 160 microns dot dispensing. You can see the new pump and syringe yourself at <www.asymtek.com> or read in EMI october -99 Volume 10 No 8 page 8.
Manufacturing has begun with some soft starts, but we are not quite satisfied with the dot consistency, the most important job just now is to rebuild the machine for constant needle-to-board operation at all speeds. So...it's not only a pump and syringe problem.
That was my october 'report'

PS. I had a dicussion about the world's most venomous spider, and I said it's an australian creep making it's net like a trumpet, lives unseemingly near people in gardens and is named 'minors' or something like. Wrong said my opponent, the most deadly is a southafrican 'sand crab spider'. Aussilek, check under your bed and tell me, I think I am right.
