Approaches are: * Thermal profiler that you use to calibrate your oven. * Any chromel-alumel [Type K] fine wire thermocouple with a cheapo instrument attached will do the job

Do you have or know of a procedure/manual for calibration on universal instruments HSC/Genesis/Flexjet feeders?

One, has anyone else ever experienced and dealt with a company debate regarding whether or not your reflow ovens should or should not be calibrated? Sure, it�s an excellent debating topic. We argue about stuff like this all the time. See, somebody

Hi, Is there a standard expiry date for a ROSE Test Instrument Like Ionographs, Omega Meters, Zero-Ion etc.? How can I verify if my OmegaMeter 500 which is almost 20 years old is providing me reliable data during testing? Note that the equipment is

Initially, whatever the manufacturer recommends. As you learn more about the how well the instrument maintains calibration over time, you can adjust the calibration period.

I worked for a medical instrument manufacturer a few years ago and we had to calibrate all measurement devices. That included everything from our vapor phase oven's thermocouples to 6 inch steel rulers. I don't see any logical justification if you'

Saw one at Apex last year, pretty cool device. Not cheap, though, as you've stated. Zarrow thinks everyone that's doing BGA should have one. O.C. White makes an instrument that does something quite similar, although I think it uses more mirrors and

ECD's OvenRIDER is the only instrument I know that can measure thermal transfer efficiency of a an oven. I suppose it would work for environmental chambers too. This instrument has thermocouples to measure ambient temp of oven zones and well as hi-ma

We are using a water wash paste for our boards which is leaving ionic contamination ( salts). In the presence of low humidity levels this creates the effect of a capacitor. Our product which is test instrumentation does not calibrate. I am lookin

Why not use the same calibration tracking, recording, and problem resolution system that you use for other calibratable production equipment, like meters, scopes, and programable controllers? If you have a reasonable quality system, then the tools y
