Yes. You need to educate your customer... On a side note, hopefully these boards hasn't gone through wave over your LF solder pot.. This will contaminate your solder pot and won't be cheap to fix it.

Just 2 cents, lead free flux residue is no clean?, how about leaded flux? how much flux residue it leaves on both types? is there a clean up procedure after wave solder? or is there a wave solder process?

For repair - passive components you can solder with corresponding chemistry. You remove the old part, clean the pad surface. Now you can match component and solder as needed. BGA is more difficult as they already balled the part with certain chemistr

JD There are many lead free wave machines out in the market today. They promised to give best result for lead free. Companies here in our country who bought lead free wave machines 3 years ago is now having difficulties in controlling there machines

Joseph, We have all been using lead free components for some time. Many passive already have a Pb free plating and we have not seen catastophic failures on them. From the information I have seen, I think this should be OK (with the exception of BGA'

Hi JD, We use the OM-310 NC for most of our lead free work and see some wetting issues. We also have a lead free produst that requires cleaning so we use the WS-819. It does seem to wet better although I have never tried the WS-819 on the same b

What's your pad geometry/sizes relative to lead width/length? Revisit this and my free website: http://www.moonmanondarkside.com and see some examples and download some free documents. MoonMan

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.

Hi Patrick Yes we have some that you cant tell the difference. BUT machine set up and angle are extremely important with Lead Free as is the dosing alloy. Cheers Greg

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.
