In one case, my vendor who is using Indium92J claims refrigeration is
not required. What's indium position on refrigeration free solder
paste. How long will it last under normal room temperature (73F)?
Regards,
M. Yuen

A good rule of thumb is to remove the paste from refrigeration the night
(or
day) before you plan to use it. In other words, 8-12 hr. will insure it
has reached room temp.

Subject: [TN] Solder Paste - When is Ambient Temperature Reached?
TechNetters,
I'm wondering if anyone can give me an idea of the amount of time needed
for a jar of solder paste to reach ambient temperature once it is
removed from refrigerated storage. The container is 90 mm tall and 80
mm in circumference. The net weight is 1 kilogram, and the product is
stored in a 40 degree F environment. Our facility consistently ranges
from 70 to 72 degrees.
I understand condensation will form if opened prior to reaching room
temp. I had planned to insert a thermometer into the middle of the jar
to get an actual reading, but I also really hate to waste an expensive
jar of paste to perform such a simple experiment.
Thanks in advance for your input!
