It was a $29 Black and Decker toaster oven -- the N&V article had
several specific models they had tested, but none were available
here in New Jersey.
I find that at 450degF it takes about 2 or 3 minutes to melt the
solder. The article made reference to crayons which melt at
specific temperatures -- you just break off a bit and watch through
the glass panel to see when it melts.
this is a trial, of course-- some things I have learned:
the oven has a tray which slides in and out as the glass door is
moved open -- open the door slowly and carefully.
a very fine tweezer is worth its price in placing components.
some items will only reflow once -- like electrolytic capacitors.
DO NOT USE THE TOASTER FOR COOKING -- remember you are cooking lead !
I am going to try the stainless steel stencils next -- these are
about as thin as a piece of paper and have cutouts where the solder
pads should be -- you apply the paste with a squeegie --
