John: Sorry I'm tardy getting back to you on this Heat capacity = [applied voltage in volts*applied current in amps*(time ending in seconds - time start in seconds)]/(�K ending - �K start) The units of heat capacity are joules per mole-degree when

You may also consider different sizes of, off the shelf, Dry Box. i.e Seika McDray (http://www.seikausa.com/)as an alternative to N2. It is mobile, no N2 hard piping, less operating expence and actually can remove moisture while storing. good luck!

I need to build a couple of prototype SMT boards and need some recomendations on some adhesive or epoxy to use to hold the parts down prior to hot air soldering. I find that some parts want to skip across the board when heated, or they want to walk
