Hello, I found the previous discussion of lead free profiles on 5 zone ovens very interesting. I had the same concerns, but have recently succeeded in creating profiles on a 5 Zone QUAD oven that have eliminated solder splatter or Solder on Gold w

We use the exact same method Chunks outlined for evaluating just about anything we're going to roll out worldwide, whether it's a material or a machine. List your factors (print speed, solder spread, etc), assign each a weight, evaluate each paste a

The component orientation was just for the calculation. It has no affect on what you're seeing. As an alternate explanation, it's possible that difference in temperature is causing the board to flex in the z-direction [as you say, it may not be f

Hi, Can you guys give me a heads up on "Traceability". I find it to be a stumbling block in my process and delays my manufacturing throughput big time. I wanna have a clear understanding of when you need it, why you need it and how will you benefit

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

Hello All, Can somebody direct me to a facility or school or even a business that can offer an x-ray course for Class 3 electronic circuit board population interpretation, as in BGA ball acceptance, connector solderability fill acceptance etc.? Some

Hello everybody, according to your experience, what is the allowed or suggested (by Suplliers,or Standards,or best pratics) shelf life for components (SMD/PTH) from fabbrication date to the soldering date ? Let's consider best case when compon

Hi Rob, I had tried printig anisotropic conductive adhesive as a replacement for solder paste. Following were my finding. Adv: - curing temp is around 120-150C as compared to 217C (Pb-free) solder. - good electrical conductivity, since it is usual

Davef, You have a good question. If we had perfect design engineers out there that would use the proper component spacing and not put SMT parts between and around thru-hole parts - glue and wave would work perfectly. I have done this with great su

Pete, I was speaking to the Electrovert/Speedline/Camalot/Gemini factory tech's and App Eng's. I now have new machine files which slowed the pumps down to half speed, I have several needles....all of which still will not place a small enough dot.
