hi we are expanding our plant, and the contractor is asking for air quality guide lines for the new area. i haven't been able to find any standards can anyone help? thx Ian T

Sorry that I'm so late responding. Your new additon probably has 'backee stains on the floor already. Assuming we're talking about a fairly standard board assembly area, you don't need to specify air quality. 1 We specify * Particulate: Level to b

I looked into nitrogen generators, it was 4 years back and I was trying to get 99.995 i think. About �20,000 for the generator then another �20,000 for the compressor you need to force the air in. I spoke with David Groome of BOC UK 01709 842358

100 PPM or 99.99% purity is sufficient for any soldering application. There are a number of manufacturers that make PSA style nitrogen generators that are great systems for electronics applications. They are low maintenance and will pay for themselve

Every plant I've worked at used copper. I don't know your criteria for better, but I would think soldering and hanging copper would be a lot easier/quicker than threading and hanging iron. I haven't priced either one, though.

Hi, Yes, we just built a new plant, and used copper again. The stuff we cut out of the old building was copper, and it was fine without any issues. We lay it on an angle so condensation flows to an end, and can be periodically vented, and we take a

Colleagues, Now I am involved into plant ramp-up where 3x Panaconic NPM-W will be installed. New production hall is being designed right now and the problem is that constructors have never met SMT shops and know very few or next to nothing about requ

What purity? To get 99.999% pure you will need dewers of liquid nitrogen or a two stage system. (and a dewer will last about a month and a half even if you don't use it as it outgasses.) But you can get reasonable purity with a wall mounted single s

Per our selective solder provider, they recommend a PSA type generator to supply the needed 99.999% pure N2. The membrane type (which we have) does not provide the minimum (99.995%) purity necessary for lead free wave soldering. They happen to sell P

yes Once I was using dewers of liquid N2 and recommended switching. I tried using air to the machine so the sensor would let the machine run. Boards went from good to a two inch icicle covering a large area. We went to a wall mounted single stage fi
