We seem to have an accountability issue when it comes to operators building defective product. Currently we are putting a piece of masking tape with the assembly #, work order, and operator initials on our black trays at the end of the reflow oven. I

It all depends on what type of board you need to solder. If your boards are small in size and low thermal mass and your conveyor speed requirments are normal, then I'd say the OmniFlo 7 will do the job. It has a max zone temp setting of 280C. The cur

I have a through hole product that is currently built with HMP solder(93.5Pb,5Sn,Ag1.5). We then dip it in 60/40 SnPb to give a solderable finish as HMP tends to oxidise. We need the HMP as our Customers solder through reflow ovens. Some customers w

You know, many SMD components have copper alloy leads and then a copper (or Ni) barrier on them. On the copper (or Ni) barrier there is the finish. Usually the finish is made of Sn\Pb (tin-lead), and if I solder with a Sn\Pb solder paste it's all rig

I'm in North Attleboro, small world. To answer your question, you can deposit small dots of paste with a syringe. Kind of tricky work, and there are small stencil soluions out there fairly inexpensively. See http://www.minimicrostencil.com/ (I do

Hello all, I am having some trouble with the conveyor speed on an Omniflow 7 reflow oven. Recent profiling showed that the conveyor was running to slow so I calibrated the speed using the instructions in the manual. After calibration there was no ch
