Some companies claimed their lead free solders wouldnt attack stainless steel, frankly they do and they should not be allowed to get away with these claims. Lead Free does not attack Cast iron

isd.jww: First, the original poster is talking about pads, not component leads. Second, you're correct that chrome plated component leads can be attached by spot welding or crimping a solderable tab to the lead and then soldering the tab to the boa

I agree that in consumer electronics there may be nothing wrong with using a lead free BGA in a SnPb process, but that blanket statement can't be made for the high reliability market.

Hi Vijai, You didn't say if you were running Tin/Lead or Lead Free. For lead free soldering I would suggest that you try to achieve as close to 7deg conveyor angle as you can. John

Is there a simple test available to test for lead content of solder. I don't need to know the specific amount. I just need to know if there is any lead present at all.

We had a similar problem with contaminated leads that was rectified by having a company strip the existing finish and re-tin the leads. After the procedure the leads accepted solder with no issues.

My recollection is that RoHS limits for lead is 0.1% of the weight of any homogeneous material in the assembly.

Target those specific parts/leads with a thermal-couple and a mole and try to get the peak reflow temps up to 225 C. It's not a cure but it will improve the apperance of the solder joints.

Hege, Yes. Good info. We have other products that run lead free process with known non-RoHS compliant components. All of these are using LF process compliant fabs however so this is the first time we have been in this position. Thanks.

If the balls are lead free you need to be running a lead free profile on the oven even if you are running leaded paste.
