This note is in response to your question about not being able to recognize a component that is running on a 4796 but has problems on a 4791. The 4791 and 4796 used two different recognition systems and the lighting calibration will be not be the s

Jan, have you try to teach on hsp4791 see if it's ok. Normally, what would happen is the lighting. Do you know how to calibrate the lighting on HSP?

Kev, It looks like you have a preheating powerplant and you still only get the board up to 85 Deg. This indicates that the preheating is out of calibration or the range settings might be very wide (Fex the preheat elements shut down at 500 and go ba

Has anyone possibly moved the location of your thermocouples? if not check the calibration of your temp controllers/ thermocouples. Russ

There are ledgitimate reasons for checking furnace calibrations, but let me clarify what that is. 1. TC's are not necessarily calibrted. Not unless you need "absolute" accuracy. TC's operate against a (non-linear) standard +/- a tolerance. Most

"...the part is aligned to the pads with in 10% before going into the IR oven." Sounds like the pad pitch might be okay (?). If that's not the problem, then what? I wish I had the answer, because I've struggled with heavy QFPs for some time now (2
