Subject: [TN] Delam or Inner Core Bond Enhance Anomaly or something else?
Good Morning and Your help is appreciated to figure out what a
discoloration is under the solder mask of a bare board which does not
change after one reflow temperature cycle.
The Prebake and Postbake photos are in my PCB Inspection Photos Gallery
at the TechNet Group Site
http://ipc-technet.groupsite.com/galleries?page=3
What is it?... Delam, or Inner Core Bond Enhance Anomaly, or something
else...?
Thanks for your help with this.
