Jack, I am not sure what the guideline states today, but our ICT folks are able to consistently hit a 0.025 pad and I haven't used anything bigger than 0.030 in probably the last 8-10 years. -----Original Message----- From: DesignerCouncil [mailto:[log in to unmask]] On Behalf Of Jack Olson Sent: Friday, February 22, 2013 10:56 AM To: [log in to unmask] Subject: [DC] Testability Guidelines I'm giving a presentation soon which will be an "Introduction to ICT". I have a lot of references, but my copy of "SMTA TP-101 Testability Guidelines" is Revision C from 2002. I would like to buy rev D, but in the meantime I'm interested to know if they have changed one particular guideline #P-6 "A 0.035 / 0.040 pad diameter will guarantee probe contact..." Does the newer revision recommend the same diameters? I'm wondering if accuracy has improved in the last ten years?
