Jan, Why don't you send your pics to Steve Gregory and ask him if he can post them for us. [log in to unmask] Thanks once again Steve. -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Lamote, Jan Sent: Tuesday, April 15, 2008 11:16 AM To: [log in to unmask] Subject: [TN] Inward formed L-shaped ribbon lead - solder Technet, During cross section analysis we came across the section of a tantalum capacitor. The soldering was flagged as non conform IPC-A 610D. In section 8.2.11 Inward Formed L-Shaped Ribbon Leads, table 8-11 indicates for class 1, 2 and 3 states for the maximum fillet height :"Solder does not contact the component body on the inside of the lead bend." If you now have a contact between the bottom corner of the component body and the solder, is this a defect ? (have some pictures if needed, don't know if there still is a "technet image upload service") After asking different people I got answers ranging from "reliability hazard" to "common with these types of components and acceptable" (including independent lab, EMS, IPC training organisation...) If something is a defect in all classes, seems to me that there must be good reason why it is unwanted. If it is common and acceptable, then I would expect to see it listed as such in the standard. Can anyone explain how this rule needs to be interpreted and what the real dangers are ? thanks, Jan.
