The correct Frequency to verify your reflow profile is about one week except when you replaced the part,equipment,the channel setting of the oven or running pilot lots.The period of the Themal board is around 50 times.

We verify ours once a month using our calibration board. You can use any board once your profile is set for a specific product. All you are doing is checking the performance and repeatability of the oven.

Background: We use a thermal boards to setup/profiling the reflow oven for pilot run.and then daily verify the reflow profile with this thermal board.Now we phased into LF production,and the LF thermal board can only withstand 25~30 times reflow excu

QS and ISO can really play a part here. If so, the best way I found was to run parallel T-couple ports to the thermocouples of the oven. Now you can run a board and gather all your thermal information and set your temps. Now use parallel ports to

Thanks a lot!

Both our Quad ZCR and our Conceptronic HVN-102 ovens have had blowers out with no alarms raised. We knew there were problems based on how boards were soldering, but don't count on your oven to tell you if anything is wrong with it. We verify once a

We verify oven profiling once a week on a scrap board and enter the data in a SPC Chart. This works out great and I have not noticed any problem. I also like the idea of sending the Profiler through the oven with the thermocouple sticking out to meas

We have enough history to know that frequent profiles are a waste of time. We check the profile once a month, after any significant maintenance, and after a changeover. Other than that we rely on the alarms on the individual zones.

How many times have you found that your oven was performing differently? this will give you the answer on frequency. We have a dedicated board and profile that we use to verify the oven operation. We perform this every 3 mos. and I believe that th

We do both our ovens once a week. If something looks out of tolerance (we've developed acceptable tolderances based on many recorded profiles over time and oven mfg. specs.) we wait a couple hours and try again. The recorded data over time is very
