I got some good feedback from a couple of engineers working over the weekend and have produced some more images to show "Fisheyes" now. I will reliable the first examples circulated as "BugEyes" as they remind me of the VV Beatle. I did find a reference to FishEyes in a NASA standard with a black and white photo. There is also a colour image in their inspection guide.

Dewey -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Bob Willis Sent: Friday, February 20, 2009 8:52 AM To: [log in to unmask] Subject: [TN] Conformal Coating Inspection I have been putting together some inspection standards for a new workshop in Germany. I have found a number of references to "Fish Eyes" but never seen an example. It's a common term but seems to be elusive in terms of actual examples. Would the images at the following link be considered "Fish Eyes" by users or are we looking for more subtle examples like two bubbles between IC leads?? www.ASKbobwillis.com/gonefishing.pdf Many thanks Bob Willis 2 Fourth Ave, Chelmsford, Essex, CM1 4HA England Tel: (44) 1245 351502 Fax: (44) 1245 496123 Mobile: 07860 775858 www.ASKbobwillis.com New Bob Willis "Printed Board Inspection & Quality Control Workshop" 24th March www.ASKbobwillis.com/faworkshops.pdf "Troubleshooting Your Assembly Yields Workshop" 25th March www.ASKbobwillis.com/faworkshops.pdf Book Bob's "Step by Step Failure Analysis Workshop" 22nd April www.ASKbobwillis.com/faworkshops.pdf --------------------------------------------------- Technet Mail List provided as a service by IPC using LISTSERV 15.0 To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt or (re-start) delivery of Technet send e-mail to [log in to unmask]: SET Technet NOMAIL or (MAIL) To receive ONE mailing per day of all the posts: send e-mail to [log in to unmask]: SET Technet Digest Search the archives of previous posts at: http://listserv.ipc.org/archives Please visit IPC web site http://www.ipc.org/contentpage.asp?Pageid=4.3.16 for additional information, or contact Keach Sasamori at [log in to unmask] or 847-615-7100 ext.2815 ----------------------------------------------------- --------------------------------------------------- Technet Mail List provided as a service by IPC using LISTSERV 15.0 To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt or (re-start) delivery of Technet send e-mail to [log in to unmask]: SET Technet NOMAIL or (MAIL) To receive ONE mailing per day of all the posts: send e-mail to [log in to unmask]: SET Technet Digest Search the archives of previous posts at: http://listserv.ipc.org/archives Please visit IPC web site http://www.ipc.org/contentpage.asp?Pageid=4.3.16 for additional information, or contact Keach Sasamori at [log in to unmask] or 847-615-7100 ext.2815 ----------------------------------------------------- --------------------------------------------------- Technet Mail List provided as a service by IPC using LISTSERV 15.0 To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt or (re-start) delivery of Technet send e-mail to [log in to unmask]: SET Technet NOMAIL or (MAIL) To receive ONE mailing per day of all the posts: send e-mail to [log in to unmask]: SET Technet Digest Search the archives of previous posts at: http://listserv.ipc.org/archives Please visit IPC web site http://www.ipc.org/contentpage.asp?Pageid=4.3.16 for additional information, or contact Keach Sasamori at [log in to unmask] or 847-615-7100 ext.2815 -----------------------------------------------------
