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.

Did the PTH barrel ends in massive copper clad ? If yes this type of poor thermal layout topside heating is often recommended.

Are you thinking for the soon to be displaced air to be able to escape out the top? Raising components wouldn't be ideal from a process standpoint.

Josh: 2222 will meet your requirements. 2221 is a companion to 2222. So, if you're going to try to get your engineers to follow an accepted standard, you might need both. Although, they probably already have both and are just playing dumb with you.
