Hi D0m0 Can you standardize on your temps and just adjust conveyor speeds for various sizes of the boards? Another trick is to parallel t-couple plug off the actual t-couples of the oven and mount the plug in an easy access point of the oven. The

Ideally size should be the same all across - parallelism. If you see different you should fix it. I would suggest instead of measuring it, to use a huge PCB and move it all the way to prove rails are in parallel.

You need to verify the Rail parallelism. Please contact Heller Service department ServiceNJ@hellerindustries.com to get procedure. Please make sure to provide oven model, serial number.

Are they getting stuck inside the oven or at the very end? If thermal expansion is the problem the boards would be getting stuck in the reflow zone since that would be the hottest and therefore the point where thermal expansion would be the greatest

Proc My field service back ground included Electrovert so I know reflow electrical quite well. I've worked on Heller, Conceptronic and Vitronics over the last few years and really there isn't a huge difference if you can read a schematic. I checked

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 for the comment regarding the CPH. In fact, the benchtop oven we have takes 7 minutes to complete a batch soldering, so you can imagine that our production volume will not be very high. We can parallelize PCB assembly and oven phase. But defi

Ron, Some places want/need oven calibration and some don't, just need a profile. I've worked for both. If you need oven calibration, an easy, inexpensive way is to parallel thermalcouple wire to your existing thermalcouples. Terminate the ends of

Establish a profile board. It should be representative of what you normally run on a daily basis, size and parts wise. Attach dedicated thermalcouples so they are permanent and will not move or come loose. High temp solder is best. Establish a pr
