Hi Wafersaw users:

Just so you know -- an update on wafersaw blades:

1.  Blades must now be checked out using the "Red Book" in the Stockroom
-- the one where you check out wafers, teflon tweezers, and AFM tips.

2.  Just a reminder that S-type blades (S3030, namely) are used to give
smooth edge cuts in silicon -- they are not strong enough, however, to
cut glass.  Please don't use these to cut glass -- you'll go through
lots of blades and these are ~$50/each.

3.  Likewise, C-type blades (namely C3060, although we sometimes have
C3030) can be used to cut glass and quartz even (although they don't
last very long for quartz and harder substrates.)  They can also be used
for silicon, but give a rougher edge than the S-type blades.

4.  Thanks to much research by Don Arnold, we have new diamond-imbedded
resin blades now in the stockroom.  These are to be used for hard
substrates, like quartz, sapphire, and lithium niobate.  These need to
be manually mounted in a flange hub in order to be used.  Please see SNF
staff if you are interested in learning how to assemble and use these
blades.

Thanks for your attention!

Mary

Wafersaw users -
	I've reserved this Thursday morning (3/27) as
maintenance time for some plumbing modifications that
need to be done behind the wafersaw.  The saw should
be available again for regular use after lunchtime.

Parts for the plumbing work behind the saw
did not arrive as expected.  I've removed the
reservation from tomorrow morning, and instead
reserved the machine on Friday morning.
