Hi Jdumond, I like your idea. If you make something working offline, I don't mind to be a beta tester. Regards, Emil

Depending on budget Valor has Solutions from vManage software suite - depends on machine type on what can be done...but they are generally vendor neutral.

My TP-11 is not getting enough juice to the upper Z-lock to pull it out of the way. Its not the locks.. I put new ones in and I get the same thing. Its like I am not getting enough voltage from the XWB. Has anyone seen this before ?

Take a look at your profile. Early on in the development of our leadfree process we saw excessive voids on BGA'S. We tweeked our reflow profile and were able to bring our voids down to about 9% or less. Also found that some paste mfgs. worked better

Exactly what should I look at in my reflow profile? Soak Times, TAL, Peek?!? I am right in the middle of the manufacturing specifications as far as my profile goes.

Ed, Send me an email to skipjack20@yahoo.com and contact info. I can give more detailed info. Mark

IPC only allows 25% max voiding. We are able to run at levels much lower than 25% by using a heller 1800 reflow oven. Have not been able to eliminate voids completly. Not even the worst case have we been above 20%.

Dave, You've got me worried - All of the boards we've tested to this point are LF HASL. Why do you say "can't be ENIG"? Am I missing something? We have not sectioned soldered boards as yet but plan to shortly. Thanks.

Joe On the earlier ENIG comment: No, you're not missing anything. ENIG board are less likely to have copper dissolution issues that other solderability protection.
