Here is a thread from the fine SMTnet Archives from a couple of weeks ago, where we spoke about the topic of mixed lead-free solder with components that have lead-bearing solderability protection: http://www.smtnet.com/forums/Index.cfm?CFApp=1&Messag

I usually delete segment repair files 'segrep' monthly without implications. It speeds the machine up when generating other segrep files. I believe it is just an archive for e-stop generated production files and has no bearing on management data. Hop

Let's examine some scenarios: What if... ...No solder sample available and you must profile a "live" board (rules out epoxy). ...Lead free build (rules out lead bearing alloys)

They can be expensive and if your using water soluble chemistry you will have to immerse the pre-form into flux. Asking the vendor to provide flux with the pre-form I believe it would dry out prior to use.

Jim Zanolli of Teka Interconnect did an "OnBoard Forum" a couple of years ago [ http://www.smtnet.com/forums/index.cfm?CFApp=2&forum_idx=44 ]. He certainly would be a good point of contact.

Jason, If IPC has no bearing on the state of the RoHS, I hope that one day some organization will. Here's a thread from another forum that hopefully makes the RoHS supporters re-think. http://www.smtinfo.net/forum/index.php?showtopic=84

Wasn't aware of that. We're using a no-clean with RF pcbs, and that's something to bear in mind for the future - thanks.

I think your refering to the sleeve. It is held in with loctite 262 or something. You can set up a bearing puller with a socket to pull it out around station 2-3. Fuji will drop the whole gear out to do this. Too much for a few sleeves.

Yes, you are correct, no fiducial correction. If I force a fiducial correction, then the placement is alright. I should also mention that the placement gets worse as the production continues. I checked the lead screws and bearing holder...looks o
