Hi Does anyone have any thoughts on Lead Free solderjoints reliability in a high vacuum environment ?

Folks, I'm looking for some specs for the maximum bend or strain that should be put on a PWB. Not looking at the solderjoints. I'm concerned with localized bending of the fab and what might be a reasonable limit for that bending. I've measured 105

Hi If I have an assembly where the solder joints are suffering from blowholes and Pinholes. Could these solderjoints be reworked/touched up to form a reliable/acceptable solderjoints ?

Looking for articles/data comparing the quality/reliability of mass reflowed SMT solderjoints versus hand soldered SMT solderjoints.

Even with PbSn solderpaste the leadfree BGA's have a superior resistance to solder-joint fatigue failure when compared to conventional parts. [Solder Fatigue Reliability Issues in Lead Free BGA Packages, Pedro Chalco of IBM, Pan Pacific Microelectron

It's been my experience that most flat pack land patterns have far too much exposed toe. It accomplishes nothing for the reliability of the solderjoint. And often the ends of the leads are sheared and not very solderable anyway. Anything more than

Hi Ken, It looks like you have some solid practical experience in the transition from leaded to lead-free soldering. I hope you don�t mind me asking a question. With conventional soldering we have a library of workmanship standards available (SMT,
