Kris, this practice has gone on for years. I have never heard of any problems associated with this. I have heard "grumblings" about tin lead parts being processed with lead free paste, but have seen or heard of no data to support. Russ

NO-LEAD COMPONENTS WITH LEAD SOLDER ISSUE: We agree with Russ. We've dicussed this several times on SMTnet. For instance, look here http://www.smtnet.com/forums/Index.cfm?CFApp=1&Message_ID=25394 LEAD COMPONENTS WITH NO-LEAD SOLDER ISSUE: We disa

No, there is no such information. Choices are: * Recognize that any voiding is a process indicator and that when observed, indicate a requirement for taking corrective steps. * Tell your quality people to quit looking at components other than BGA wi

Hi everybody, We have wave solder fixtures made of Durapol and multiple wave solder machines. Most likely we�ll use the same pallets for either tin-lead or lead-free solder for a while (of course after washing the pallets). Should we test the palle

It may be you should look for higher TG of Durapol Rgds GS

My policy is not to mix them. You have zero cross contamination potiental with this policy.

I don't think that you would need to test these. Have you ever seen any evidence of solder sticking to them? We use the same material and never notice anything besides flux staying on the bottom. Would the lead absorption if any even be of a concer

Is there a limit to the time that most components can stay at temperatures around 130-200 deg c? if i slow the time, the first 4 zones will be at this temp for about 5 minutes in no lead process. i am concerned that some chips wont be rated at this t

If you have concerns, you can look at the datasheet for each component or contact one of their application or materials engineers and find out what the components are rated for...process-wise. IE, how long can I be in the oven with this part, at what

Hi We are in the process of developing a lead free product to be used in a non lead free selective soldering machine, i do have concern in these, and hope you guy can share your experienced expert opinion: 1. What does it take to convert to lead fre
