Earl, How are things? Thank you for returning, and hopefully staying. You've made many good suggestions on running the site. However, it required a lot of thinking and resources to get things done. I gave it a good try, and thank you for compleme

Hi Wayne, Why do you feel that your solder pot needs a fountain for this application? It is always nice to have a mini fountain wave but it is not always a must. Good flux and a steady hand go along way. Iether way you will need a steady hand! Th

Steve: A couple years ago, I decided that I needed to broaden my education in the areas(s) that I make my livelihood � soldering and assembly. I had attended some excellent (and some not so excellent) tutorials at NECON, but just felt I was missing

I'd have to disagree with the Electrovert applications guy. I'd recommend SLOWING down the conveyor between .5 to 1 FPM - effectively, you're REDUCING contact length (because contact length = dwell time * conveyor speed), hence getting better peel-o

You bring up a very good point. From what you have described I think your email client sets up individual connections to the Internet for each item it has to download. Since the thread subscription is in html format we can put in supplementary item

Rich: You should raise the issue until someone BIG smacks you!!! We were getting deliveries from our distributors and virtually every part number had an opened dry pack. We kept SCAR'n the dudes until they came in and sat down. It took a while ..

We just bought a new Heller 1800 EXL reflow oven for reflowing SMT boards. We us a low temp RMA solder paste with 2% silver. Everything we build is to IPC Class 3 specifications. We have approximately 600 different types of circuit boards we build

Let me be more specific about my dilema. We have used a vapor phase reflow process for many years. We just bought a Heller 1800 this year (2000). We may very well be able to run all 600 very different board types we build in 10 recipies on the Hel

Let me see if I've got this straight...rather than hook up a MOLE or a KIC profiler to each and every board (600 P/N's in my case), most people are making judgement calls based solely on how similar a board looks to another board, for which they have

Rich: Now that�s a great question!!! You�re corrrect. Primary-side temperature is the driver of the differences in the sensitivity to moisture between SMT and PTH devices that you�re finding. * Primary-side temperature for SMT ~= Secondary-side te
