Mf Eng, I am impressed! A real Engineer, quoting from his sophomore year Thermodynamics class, "energy is neither created nor destroyed." I believe that's the 1st Law? I agree with you on your points, 'cause it'd be my guess that if the pot is lef

Wow, I surfed this guy's homepage, and he seems like a complete imbicile: http://michaelbluejay.com/ He'd be the type of guy (with ZERO credentials - he's either a OUT, or has a couple semesters at Austin Comunity College) that you'd see touting th

You'll need to calibrate your effectiveness to the deliverables of the adhsive quality and initiate the description of the criteria for requirements by developing a framework for the application architecture consistent with the planning corridor spec

Have anyone perform wave soldering on FR-2 and FR-1 printed circuit board with lead free soldering? Can you share the parameters(wave temperature,preheat temperature, contact time, wave height,etc,) used and did you do any changes to the wave solderi

Is anyone wave soldering 0603 leadfree succesfully? We have no problems soldering them leaded, but lead free we see a lot of random skips and some shorts. We use SAC. We have tried different fluxes, flux settings, playing around with preheat, sol

No, we haven't compared bills because we rarely let it cool completely down over night. I would think that the cost needed maintaining 200C over night versus 310C over night would be about the same, but a little less. But going from 25C up to 3

Ok smartbutt, you can play evil guru all you want, but you cant dispute math which is a constant thing even on your side of the planet - which you think is the smartest. Letdo the math shall we? Even you have to turn your pot on to solder. You hav

The answer is simple...kind of. The short answer in terms of total cost (if you don't run an air conditioner) is there is no difference. The technical answer is: The First Law of Thermodynamics - Conservation of Energy applies. You have an entire s

I am looking for effective ways to secure through-hole components (non-clinched) to the boards for wave soldering. Can someone share their ideas or methods? We've tried vacuum packing & tacking/masking, but there must be better ways. I'd appreciate a

Greetings, Is there a Mil Spec or IPC spec on how many times you can wave solder a PCB? I did a search on this forum with no results. Common sense says two or three times. I need documentation.Thanks for any info.
