<DIV><BR></DIV>
<DIV><FONT face=Arial size=2>I ordered components to build an OZY. The Altera
IC's from Arrow came in huge opaque sealed bags. My first thought was I had been
sent circuit boards, or massive quantities of IC's. On closer examination I
discovered labeling that said the contents is moisture sensitive, and if reflow
soldering or other high-temperature process is to be used, it must be done
within 168 hours of opening the bag. There was a hint about some kind of
moisture monitoring device in the bags, which might explain the bulk. I
don't have experience with reflow soldering, but I am guessing I can ignore the
issue as long as I do the soldering the amateur way with iron and added solder.
It will be some time before I will have time to do the soldering, but I
would like to verify what is in the bags a.s.a.p.</FONT></DIV>
