The CCGA packages that we install are still a tin/lead alloy and not a SAC alloy. They were 90/10 SN/PB. I beleive that this may be one reason why the difference.

I'm sure that we have all seen it but it can be from so many different things. Definitely can be from flexing, Are you 100% sure that they are good prior to this install remove process?

Remember that there is a difference between protecting the Interface Computer and the Machine itself. One is reletively cheap, one is NOT.

Take a look at the boards, too. Could the HASL be different (in particular a domed or convex cross section) than what you're used to seeing? Is your printer actually working properly?

Thanks Mike, Unfortunately I am limited to the amount of time I can run preheat along with the limitation of only two different settings/cycles. Looks like its time to get a higher end rework station.

adlsmt, Solder pot temp is set to 265C. About solder joint quality, you must take in consideration the PCB finish when testing different leed-free alloys. Our PCB's are ENIG.

Depends on what you're kind of thru-hole you're placing. Cutting, forming and placing TO-220s are a lot different than VCD components. Can't just slap any ol' name out der!

I will probably be having a conference call with Qualectron about the Shindenshi AOI machine. I was wondering if anyone has any experience with this machine. Especially if the newer one is notably different than the ESV-304.
