You're right, but my neighbor borrowed my X-ray fluoroscope XRF and never brought it back! Actually, I just read the spec sheet which told me it was tin/silver leads.

what did you reprofile to ? did you increase the peak reflow temperature ? can you tell form what to where ? I bet your vendor told you process guys that it was " drop in" for a tin leaded plated part.

not keen on pressing myself lot of stress can lead to delam and cracked solder joints, I prefair CNC router, lot of dust but if its extracted well its very good and stress free in more ways than one

Anyone have any recommendations for hot air, hand held rework stations? We currently use Hakko for leaded assembly. We already have a sniper for bga rework.

Follow your component supplier recommendations. For instance: Xilinx says their lead-free alloy for their BGA spheres is SnAgCu, and liquidous is 217*C and they want you to peak at 230 - 235*C for good wetting according to their reflow guidelines.

Not knowing your company, I would treat LF boards as a new part number. All boards are sold in lots, so controlling both part numbers at the same time would be easy. May add to your inventory but beats mixing.

We have the pb free symbology embedded in copper on the fabs.

do not forget,ROHS Directive does not allow other chemical substances (ie. PBB, PBDE,....) that could be in PCBs, so the PCB must be ROHS compliant and not only Pb Free. That means be carefully when marking PCB or PBAs. Regards..........GS

Have any of you used or evaluated lead free water soluble paste from kester or indium?
