There is no formula out there that chooses a model for low volume high mix. Every oven can manage the throughput, which leaves us with cost, servicing, flexibility and reliability. Ersa Pros: Longer heated length than the ovens I am comparing it t

Thanks for your help every time! You are right table top units are a joke. For smaller conveyor ovens I found two major brands: Manix (no longer makes ovens) and Manncorp. The manncorp unit I am looking at does not have a bottom heat zone. Mos

We are having a problem with our Heller 1800W oven with certian parts skewing. It seems that some inductors and taller Can caps are shifting around in the oven. It seems it will solder fine and than all of a sudden just be off to one side or the othe

A few lifetimes ago I went to a seminar on reflow profiles. The speaker emphasized more than once that the cool down rate is important. Someone asked him about controlling the cool down rate and he acknowledged that you can't. And IIRC it was an ove

Hi, The focal point of my research has been to recommend a reflow oven and develop a process for a small to low-medium production SMT soldering with the following considerations. - Lead-Free - Low to low-medium production - Forced Convection reflow

Hi, We had a similar issue to this. When we examined the boards at x-ray there were no apparent defects, We sent the boards for Dye and pry testing and we found that there were crack or gaps between the paste on the PCB and the BGA ball. basically th

hi, I have a big problem with soldering uP QFP144 package.All components in PCB are small, only this chip is big and I can't make good temperature profile.Solder joints of other components are shining and with good wetting, but in QFP leads solder j

I have been trying to get the profile right for this part(OMAP3503DCBC) , but still struggle. I'm using the Herller 1809 MKIII oven. I look at the profile recomended by TI and still issue with the solder ball collaps and wetting. My peak temp @256
