This has been debated several times on this forum, but I have to say the opposite of Samir. I would rather see a SnPb BGA in a Pbfree process(as long as the component can take the heat) than a Pbfree BGA in a SnPb process. There has been some mention

The "marketing geniuses" of the world are now touting lead free ovens, lead free irons, and even lead free smocks, heel straps, and even G-Strings! Bottom line is - ya just gotta get it hotter, stupid! There's nothing "RoHS" about equipment besides

To have symbol embedded in PCB copper it could be an opportunity for error because in case of mountinng on it a non ROHS compliance components/devices, the symbol would not tell the true. Better use the Rohs compliant label, stiked on PCB when sure

yes you can use lead-free components and/or lead-free solder paste on Sn/Pb PCBs. You do get reliable joints. as already mentioned, it doesn't meet the WEEE and RoHS requirement. Indy

funding from who?. we are dealing with the same thing here. the solder paste cost is roughly 1.5 times SnPb, and the cost of bar solder is thru the roof

If you are using lead solder (SnPb) HASL is a good choice. If you are using lead-free (RoHS compliant) solder then I would recommend Immersion Gold (ENIG).

yeah, I wonder what will be the next? "Do not touch with same fingers PCBs with SnPb and Lead free PCBs as some molecules of lead may stick to your fingers" :D

Mat, Are you sure you should be using SnPb HASL boards if you are doing prep for lead free? If you aren't actually going to comply with RoHS then fire away. Nearly all of our assemblies are now ENIG and as any re-design comes up on a HASL board it is

We've never, to my knowledge, sent out Pb-free BGAs to be reballed for use on an SnPb assembly. In fact, we developed an in-house reballing process and we haven't felt the need to do that either (for salvaging an occasional reworked part, maybe).

We not sure what your supplier means either. So, maybe it's worth a follow-up call. One possibility is: The HASL could be lead-free as easily as it could be SnPb. You probably need to think about how you're going to change your reflow recipe to in
