Dear Techies Thanks a lot for the above topic replies ; and the sympathy and condolences expressed . I appreciate them all . However on the subject itself ; I did get little to cheer me up : Still stuck with the task of explaining why to run precisely profiled reflow on SMD's if the repair (yes; documented, trained, etc.) does not reflect it (and as the inquisitive one's found ; almost 80'C/sec rise IS a toll ask on reliability initial conditions . I did get a lot good points as : " they go through wave on bottom ; what's the point ?" ; etc. ; still ; little of quantifiable lines . So I presume this is one of taboos to be let to sleep and not disturbed even by the top folks on reliability and metallurgy ; which is kind of surprising to me ; I thought we deal with puzzles ; not dodge them ; even if they're aired by a wise guy like me . Therefore, I'm still in a flux of mixed feelin's ; but if even cruise missile guidance systems are allowed iron rework ; I'd give up if I could . But I can't (my friendly but stern EU inspecting buddy 's coming back for answer) ; if any of you'd take a pity on me (for the tech reasons I mean) and release some IRON reliability works ; papers pointers ; etc. tied with the shock motto, on leadless mainly ; I'd be sincerely grateful . My apologies for grinding this over ; you're still my best hope .
