I am trying to assess current industry thinking on the question of whether or not lead-free BGAs (SAC or other) can or should be soldered in a tin/lead process. It seems there are differing opinions on this and I'm wondering what some of you are doin

Is there anyone performs solderability evaluation on PCB as a part of receiving acceptance criteria. It's costly to perform any form of physical evaluation whether simple as dip and look or wetting force balance. How do you have control in place to a

Has anyone come across any good visuals for the solderability requirements for component leads with toe-down configuration? IPC-A-610 does not have any visual aids for this category and our inspectors are having a difficult time assessing based sole

Jorge: I took this total posting to several fabs at IPC APEX. None was satisfied with the answers you receive from your supplier or the Forum members. They suggested that you get your board analyzed. They were surprised that your supplier didn't in

Is anyone successfully and repeatably placing 0402 or 0201 components with an older GSM? We're looking at the possibility of quoting a new job with 0201's, and I need to assess the capabilities of the machine before I commit to the job. I've never

Hi Steve, I agree with your assessment, it would certainly seem like the pads are de-wetting. But what could be the cause of this? Contaminated solder? The boards are new out of vacuum sealed bags (with desiccant sachets), so I can't see it being the

You proved that the standard solderability test of components may be effective for assessing aged components. Curious Minds Can you get the authorization to use a more aggressive flux? Will that flux solve the problem? What's it going to cost to qu
