Hi techies, We just purchased a new oven (Heller 1900w) it is 12 zones. We are not using the first two zones only using 10. The machine set up is 80,100,110,120,140,150,170,175,230,265 and conveyor at 65. The profile looks good, peak temp at 220, max rise at 2/sec total time above is between 50 and 60 sec. My problem is when the board exit the oven they are very hot! I mean these things are flexing, is this normal for a 12 zone reflow oven or are we doing something wrong? Any help would be appreciate Thanks Angie Quadrus Sr Process Engineer [log in to unmask] ################################################################ 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.
