We are looking for a low production p&p machine. Which trade show can be a good one to attend (USA) where most of the manufacturers can be found? Regards, Rafael Fematt

Don't forget the massively attended NEPCON- East (Boston MA) show just last week. Just go to Vegas.

This is what happens when goverment legislators buy into all the enviromentalist nonsense they are feed without taking a solid look at all the facts. I am for using our enviroment wisely but this appears to be a case where they are going to do mor

SN100C is popular for wave soldering: http://www.nihonsuperior.co.jp/english/products/leadfree/ Its good for Pb Fee solder finish for HAL on PCBs too. Wave solders better than gold finishes.

Smt paste= SAC305 Wave Solder= SN100C no real problems with either of these. good luck

Don't forget that leadfree solder can leach the iron out of old solder tanks. Make sure yours is compatable with leadfree solder. You don't want the tank disolving, unleashing a tidal wave of molten solder.

Thanks to all of you for the positve input, I understand that my best option, after reviewing opinions and certain studies, that SN100C is adequate for wave and SAC305 for SMT. Thanks again.

I have not seen hold size as an issue when switching Sn/Pb to Pb Free wave soldering. Trying increasing your dwell time in the wave- typical for Sn/Pb is 2 to 3 seconds. Try 5 seconds to see what you get.

60% ratio would be great start. that is what we typically shoot for with all leaded for the most part. 25 mil diameter in a 40 mil hole, works great for auto insertion as well Russ
