[EE] Shelf life of SMT paste solder | Piclist

A discussion group for the PICMicro microcontroller. Also called the Microchip PIC, this list is dedicated to the use and abuse of this fine, simple, microcontroller. Close to topic posts are welcome, ie. general electronics.

I would like to use SMT paste solder in syringe form for my modest PCB construction. I understand that this stuff has a shelf life which can be prolonged by refrigeration. My local distributer can supply this to me from Kester, but I need to buy 5 tubes at a time. The price per tube is good, ~6 bucks/tube. I would like to know what is a practical (not theoretical) refrigerated shelf life for this? Is there a better place to purchase it? Is it a crazy idea? Any enlightenment will be appreciated.

I am using solder paste from Soldering Technology. Bought a single syringe in Jan 2003. Kept in fridge, and am still using it. Put part of it in a dispensing syringe, which comes in and out of the fridge, the balance stays in the fridge all the time. Shelf life of the paste is supposed to be 6 months at room temp.

Six syringes should last you a life time.
