Hi Everyone,
We've got a request for feedback on the anomaly in the attached .ppt file which was detected in one bundle of glass in a coupon. This is in the center of the board stack, which is a 24 layer construction. Since it is in the core material it may be related to glass non-wetting of the resin or poor glass treatment.
I'd also like to know if this is something we can consider developing criteria for in the next generation of IPC-6012/A-600 when we meet in Las Vegas in a couple months.
Regards,
John Perry
