Stella. I know this sounds silly. Replace 805 pkg resistors with 605 pkg resistors. Believe me it is a wiser option than fiddling with pull test, vibration test, reliability test....so on. Anyway, Who is your end-customer, GM, Chrsyler, Ford, Nissan or Toyota? Hey, making sure my next car won't crash on me with repair bills...

We have a number of boards where 0805 package resistors were placed and reflowed on the 0603 pads. As the results there is no side concave solder fillet, only under the component terminations. What options other than scrapping the boards would you suggest? ( Rework: remove and replace. Do some testing (vibration, pull test??). Please, help Thank you, very much Stella N ################################################################ 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.
