Is your oven suitable for Lead free temperatures & can it achieve a decent profile across your complete range of boards? AOI will need to be looked at too as the joints are not as shiney. Cheers, Rob. PS. Where's Thisbie?

We are a military contractor and need to build to IPC610 class3. We are receiving many parts with palladium leads and currently use a No-clean solder paste. We have evaluated OA pastes with very little improvements. Without a touch up of all leads th

Yes you can use no-lead parts in a leaded process. Your solder joints will be weaker than they once were unless you change your solder paste. You can try to improve this by running a hotter reflow temp, but be careful since your flux was not design

I agree that it would be crazy to think that every part a company manufactured had to be re-engineered to allow for higher temps. Out of the question and I NEVER implied that at all. What I said was that Zarrow told us that it was alright to use lea

You know the old addage, "Those who can't do teach." From my own experience with some of these "well-known consultants", they know lots of textbook theory, and..they speak in buzzwords and cliches (just like their magazine articles). I'm not saying

Good afternoon. From what it sounds like is that the solder joins are not getting hot enough or if it Au, then the increase in the Au content of the joint is increasing the melting point of the final solder joint. To some extent, this will also hap

Phil is wrong. In the real world, we know that part mfgers have not changed every one of their parts to make them "high temp". They just changed the plating. Anyone who thinks otherwise, has never run a profile or touched a warm board coming out o

Pd takes longer to desolve than the materials yer used to using. Search the fine SMTnet Archives for background on modifying your reflow recipe.

I agree with prior postings, but there is no perfect yes/no answers, right (left)...? Only good questions to be answered. I think it is overkill to have an extra stencil, why do you need it? (That is if you have a proper stencil cleaning equipment).
