If the problem appears to be random... we had a similar problem. We found that the belt which feeds the PCB through the reflow oven would jump or lurch ahead. It was barley noticeable but if you have identified the frequency and time of the compone

No delta T issues as I am not actually reflowing the component to the PCB. This is for moisture sensitivity testing as per JEDEC 020C Standard. Trying to duplicate a profile in the standard and am having trouble reaching a component ramp rate of 3

I am testing some BGA's (PBGA 30mm x 30mm) to evaluate the maximum ramp rate we can achieve in our reflow oven. Temperature is being measured at the body(top) of the component / not leads. After several trials (with various oven settings), the high

Try an experiment where you profile the assembly with 3 consecutive boards in the oven spaced just 1" apart versus just 6" apart and then 12" apart. You figure most ovens have about 12 - 16" heating zones, so for your typical 8"x8" PCB, you'd have w

Can anyone tell me if there is an industry standard on how much of a space should be between PCB's in a convection reflow oven? Thanks

Just Curious why would you need to reduce the air speed by 80%

What paste are using? You should referance the manufactures time and temperature specification. Running lead-free in a 5 zone oven can be done with out a problem but it is not production friendly. If you are concerned with through put I would look fo

Hi Boys and Girls, I've been given the "task" to turn off the nitrogen in our reflow ovens. I am using the BTU, TRS series ovens, each with eight zones. Also, I have a couple of new BT Paragon ovens with 10 zones. We currently are running Qualite

We can't do that because we are using dual ligne reflow oven..So the two sides of PCB are soldered with the same reflow profil.
