Hi Alexei, We have met in the past ( simona - > PCB ) Thank you for this input, I might consider > it ! Hello, validating a whole line can be tricky. I can advise you to validate each machine (not the transports) and then put them together in one

It always surprises me how many variations there are for profiling and controlling your ovens, and the thing is most of them are fairly valid. Here's yet another option: Your board profile needs to be specific, 2 boards can look identical but have ve

Sebas, Curve you attached is using different temp table. We need valid data to evaluate.

Ovens, and any other process for that matter, will ALWAYS vary. It's called process variation. I do Cpk (process capability) on my ovens. I track time-above-liquidus and peak temperatures. Statistics will validate how repeatable your oven is.

Go with the KIC 24/7 system. Does all your monitoring for you and generates your cpk. Only have to run a golden board once it takes care of the rest.

I have made couple of investigations with our oven. I set-up 5 product profiles and run a thermal profile measurement and record them. Then I set-up one more product profile and rename that as Validation Profile then measured the thermal profile. A

Thanks everyone, I have found your postings very helpful for reflow ovens and intend to review my reflow calibration and validation, but in this particular instance I should have been more specific. We use the non conveyorized type of oven (Ten

There was a discussion on this a few weeks back. Basically if you HAVE to do this because you have an older oven that you dont trust or your customers/ISO force you to do it then just do it monthly on the test board only. Doing it on the test board a

Validating your oven is a good thing. Build your own vehicle that is wide enough with integrated/strongly attached thermo-couples on it. Use always the same vehicle with thermo-couples on the same spots and run it through the oven for verification. I

The problem expressed by you need not necessarily be caused by the Reflow process even though it's effect cannot be ruled out. I suggest to validate periodically the Reflow Oven performance as also optimise Reflow parameters through a documented vali
