I am not a real master of odd connectors, but I am pretty sure that Fuji will write you a PD free of charge if you send it to them. I have sent them parts before that I coulnd not figure out.

Hi All, I have some question about expired solder paste. What would be some of the effects regarding assembly quality. Is there any changes in flux composition toward the end of shelf life? Thanks in advance for any replies.

All of what Dave says is spot on. I suspect that the most likely corresponding defects on your assemblies would be poor wetting and insufficient solder.

Flux seperation is a common problem observed due to expiration of paste. The symptom is a yellow layer of flux when you open the jar. Excess flux separation will cause priting problems such as smearing and slumping.

Thanks for the reply. Just one more question. If there is less solvent but the residues are harder to clean. would there be more contaminant left on the boards? Has anyone did a cleanliness test?

Yes you can, although we don't think it's a good idea. Look here: http://www.smtnet.com/forums/Index.cfm?CFApp=1&Message_ID=48159
