Did a quick search and found two types - both silicone based - SILPAT and Silicone Solutions.  SILPAT sold at Target and Silicone Solutions at Wal_Mart.  There are apparently two types - thin transparent mats to be put over regular steel trays as well as thicker stand-alone cookie sheets.

Had not thought of that source, Sandy.  A cookie sheet might be just the thing.

Thanks again

They also make cookie sheets and baking pans out of it.
You might be able to get it at Wal-Mart for a couple of bucks
if you need more.

Neat Idea, Ernest

Might be less work than trying to develop a manual "pick and Place" gantry
{:>).  I wonder what is easy enough to cut but will withstand 468F for 90
seconds?

 The most difficult part of the experiment was placing the components
without rubbing the solder paste off the pad and knocking another
component askew. I now understand why they talked about "arm rests".  It
doesn't take much to get misalign.



Ed, get a second piece of plexiglass cut.  This one to have large holes to

clear the solder pads, but comes in to the thickness of the components.
The idea is to drop the components into a hole that will force them into
alignment.  All the better if it's made of a material that can stand the
heat of the oven.
