Hi, We are also interested in this, and I have heard you can get the PCB's with the via's plugged. Also, if the via's are small, the solder should not penetrate? Anyone have any further info? Grant

Hi, What size via's are you guys seeing, as the ones in our products are incredibly tiny, and via's are very small now days. The via's on the boards we have are dramatically smaller than the pad on an 0402. Grant

You're correct. It is a good sign for Americans. It's a shame the Euros let their emperors run around in their skivers.

The method that you are using is the same method usually used by other fuji user. Their is no other way of doing this. Mastering this, make this job so easy in the long run.

Ya probably most used equipment guys do skip that step on the machines they sell as "production ready" As for us, our machines need to actually build boards without going down on the errors that dirty clutches create....you silly man.

Agreed, if your process is the same than most likely you received in a batch of lead free BGAs that are supposed to be leaded. Happens to us all the time and vice versa...

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.

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.
