Good afternoon,
 
Has anybody started buying boards fab'd using Isola 410 or Polyclad
FR-4-370-HR and had difficulty breaking the boards at the v-score?
 
We have some 0.090 boards that were cut down to 0.030 and were still
difficult to break apart.  Had them reworked to 0.020, but I'm worried
that this may be too thin.
 
Thanks in advance,
 
Phil
