Gaby, Sorry about your troubles. I've never run into it with through hole devices, but many times with SMT types having been reflowed and often needing touched-up because of poor solder termination solderability. It sounds and looks (in x-section) like a smilar problem. The fine coil wires become detached under thermal stress because of dissimilar expansion rates at the attachment "legs." We solved some, not all, problems by changing a supplier once to improve solderability. In another instance, we more carefully watched our profiles to do everything possible to avoid touch-up. Good luck, Earl Moon ################################################################ 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.
