Subtle spamvertising there. Lower Cost small machine brands worth looking at are probably: Mechatronic Intelligent Drives (UK only?) TWS Autotronik or their Manncorp branded models in the USA Fritsch Innotech Heeb (a virtually invisible market share

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

Is this fluxed / solder paste or flux-less reflow process? Are you soldering in a nitrogen or vacuum oven? From my experience having gold-tin connections go through reflow a 2nd time does not yield defects or quality issues. However, I cannot comm

No parts or boards are baked unless they are moisture sensitive and were left out too long and that is for reflow only. In your case there should be no reason to bake becouse the boards should be vacuum packed as they come in as well as any moisture

This has been a problem with new components coming directly from vacuum sealed desiccant packed moisture barrier bags with moisture level cards. We have also baked all boards prior to the BGA rework to ensure no moisture issues were addressed.

Here is another visual. http://www.metacafe.com/watch/416435/computer_fan_generator/ Only issue with a PC fan is I'm positive that the blades will melt while enduring the heat of the reflow oven exhaust.

Thanks for the feedback. I was looking into solder pastes and saw some advertised specifically for low voiding by Indium and another supplier. This is customer driven - requesting voids in the single digit percent for components with thermal pad

Another oven maker not so famous in USA probably but very strong in EU and high end Asia companies is Rehm Thermal Systems (germany), you should take a look..... They have many years in Reflow same time as Heller been in business, but they use highe

We are looking at several reflow ovens with intent to acquire one for both air and nitrogen reflow capability (i.e. have the capability to reflow in either air or nitrogen environment). Would be interested to know what I should look for in comparing

Q1) How to identify on good or bad RF shield that could contribute to dewetting? A1) We use Alloy 770 and 752 [German silver] for our RF shields. We have never seen a solderability issue, even aged stock solders well. * Nickel Alloy 752, Nickel Silv
