Hi, I have taken the profile.The peak temp. at the lead terminal is 219 degc, duration above MP 54 sec and duration 125 deg C-160 deg C is 60 sec.

I think it will make some progess if you modify the program and let the component shift towards the lead orientation as possible while P&P.

Which specific JEDEC standard are you talking about? It's very peculiar that JEDEC would publish such a standard.

Kevin, Agree with John's thoughts on profiling and the max temp of 240 degrees in particular. To add to it a bit we have seen the following parameters put in place at many assembly houses to protect against overcooking the components: --Time above

cal, hahahahaha. "40,000ft overview". Indeed! Thanks for the lead. I intentionally left out details such as $$$$ in hopes of obtaining a broad list of suggestions. From there I can better assess what to focus in on.

If you are using wave pallets, you could attach copper thieves to the pallet to draw the solder away from the leads.

Here is an opinion p.1/p.2 is %@##& stupid. Keeping files in different folders with the same name can lead to a mess if one person one time makes a one mistake. Could I call this company and order a p1? (rhetorical) Russ

Dave, I believed you are really experienced in SMT soldering process. What I meant good connection, should really be "Visual check by naked eye OK". From your message, there are situation of "marginal solderability" that will lead to uncertainty
