Whenever
a diamond tool cuts through a soft metal such as gold, some kind
of burr will form on the cut edge. Frequently we can select combinations
of blades and speeds which will minimize the burr. For example,
a 1 mil burr on a capacitor with a coating of 200 microinches of
gold is usually not a problem.
However, in some applications even this
small burr is unacceptable. In that case PST can provide chemical
etching and vibratory finishing operations that will remove the
burr and etch back the metallization from the cut edge. Contact
our engineers at Precision Surface Technology and we will discuss
the best solution to your problem.
