Dear collegues,

We are a producer of R/F pwb's. The great majority of jobs run in very
small numbers, so we have to avoid expensive tooling. As a consequence,
all machining of part-components and finished panels is done by nc-routing.
Unfortunately, we have been unable to avoid burring of the quite tough
polyimide laminate. Therefor, a substantial work is put into manual
'deburring'.
This is a very time consuming operation which we would like to avoid. Any
advise regarding optiming routing or experinces with possible alternaive
methodes, e.g. water-jet or laser cutting, would be very welcome.

Regards

Torben Oesteraa
