ve, If the contract with your supplier included their meeting the acceptability requirements of IPC-600E then you may have a chance of some negotiation on the boards already built that exceed the 50% limit. In my opinion though, the 50% limit was written for punched holes not straight = line board edges. The amount of haloing with vary from board to board dependi= ng on how the cut intersects with the glass bundles in the laminate weave. = If you twist your supplier=92s arm on the ones already built, you will find = the next order will have a price increase or they may refuse to build them.=20 FR4 in my experience does not perform well when die cut. Paper bas= ed laminates can be die cut with less edge damage. With traces only .015=94= from the die cut edge, your design will be an on going problem particularly as= the die begins to wear.
