Can anyone define what is discoloration in IPC 600 regarding fab's goldfingers? When I see a goldfinger that is not as shiny as the other ones, should I consider then that the finger is a defective finger? Personally I think the requirement is very subjective and hard to define. Is there any inspection tool people can use to determine whether or not a discolored finger is acceptable/rejectable? My last question to the group - is discoloration a functional defect or cosmetic defect? Thank you for reading my question. ################################################################ TechNet E-Mail Forum provided as a free service by IPC using LISTSERV 1.8c ################################################################ To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE TechNet <your full name> To unsubscribe: SIGNOFF TechNet ################################################################ Please visit IPC's web site (http://www.ipc.org) "On-Line Services" section for additional information.
