Oh, thermal mass

I used my rev B stencil to apply some paste to an extra rev A PCB to test my ability to solder bityExpress.  Unfortunately I had poor results.   I couldn't get the paste hot enough to flow evenly.

I'm not sure if the issue is with the larger thermal mass of this card or if I need to adjust the IR lens a bit more.  I was discouraged enough to look into toasters.
