Hi John:
Have you tried to drill with water. Water will
not burn the material but will drill very easily. Maybe you already have
tried it. I wonder how small a water jet can be formed. Hmmm.
Regards,
Ramon

I guess that if you want to learn and at the same time pass on
experience, you need a forum where you are able to learn from your peer
group and also to teach in the same forum where you may have extensive
experience on a particular issue.
That is the point of a forum like Technet - I started the UK based trade
association the SMART (Surface Mounted And Related Technologies) Group
in
1984 on just that principal, a forum where data could be shared and
peoples'
learning curve reduced significantly.
So I do not find it surprising that the level of data sharing is high, I
was not surprised for instance at the 6 mil drilled hole comments - if
you have ever tried it you will know that the major issues are getting a
good drill source, beyond that you need to turbo charge your drilling
machine to 180K RPM and beyond and then there is positioning accuracy
and debris removal....8-).......use a laser.......
These points and others like them are well known if you take the time to
fly around the world and visit various companies, but all it will give
you is a starting point. The real key to using information is to have
the engineering vision and expertise to apply it and be able to produce
the result cost effectiveley and repeatably in a commercial environment,
otherwise the data is only that - data.
If you really want to keep things to yourself, patent it..........the
world will be aware of it, will either infringe it pay royalties on it,
or challenge it, but at least you can hang the certificates on the
wall.............8-)
I believe that the technet is a very useful forum. I can however see the
need for an alternate forum for high technology PCB's since I have
managed to fall off the edge of technology twice in the last couple of
years with high later count boards using 10 mil drilled vias in thich
boards, we actually reached the limits of the laws of fluid dynamics for
the in hole solution changeover which we proved by designing a test
coupon to show definitively where the process capability ended. For
these issues, Technet may not be the right forum, since when I explain
what I do with high tech circuit boards to most people on the
manufacturing side (and I am one) a glazed look comes into their eyes.
For the record, if anyone wants to know how to connect 40 micron pitch
flip chip on flex, control an anisotropic bonding machine in real time
using real time bond line resistance measurements, or how to get
absolute Z axis depth accuracy on back drilled backplanes, I would be
happy to send them copies of my patents..............
I believe information sharing is a good thing, if it really is worth
protecting - do it through the patent office.
In the meantime Technetters, keep up the good work, and have a great
weekend wherever in the owrld you are.

Rudy,
I'm either not understanding what you are saying, or if I do understand
it, I disagree.
Most of the information passed on TechNet is in the public domain; it is
stuff we learn from tech articles and seminars and stuff that "everyone
knows" who has been around awhile. I don't think anyone is passing on
intellectual property via tech net, no matter where they come from.
Did you mean to imply that other cultures (other than American?) are
more open and sharing ?? ..... There are a lot of American technetters
that give a lot to this and the other forums. The actually percentage of
participation by "culture", since it is a self-selecting group, can't be
used as a barometer. For instance, if you proportioned the participation
by dollars-shipped per country, that would change the percentage
participation as a function of dollars per technetter, to show higher
participation by Americans ...
Did I totally not "get it" - what you were trying to convey?

In fact, the amount of information passed around on Technet is slightly
astonishing, that it is done so easily, and freely.... I find it telling
that the participation on Technet does not reflect the national
distribution of PCB production... that is to say, the majority of the
participants on Technet come from cultures that are more open, and
sharing...
