Search the PICList archives at http://www.piclist.com for "toaster oven" - there is
lots of past discussion on this.

It heats the board.

> Would it be possible to build such an owen yourself.

There was a thread about this a year ago or so, check the archives.
Somebody claimed reasonable results with a modified toaster oven.

By the way, it's "oven" with a V.

If you mean a pre-heat oven, then it's purpose is to bake out some of the
moisture that the board has absorbed from the air during storage. Apparently
this will cause delamination in the epoxy/FR4 layers if the board the board
is heated too rapidly. Such delamination can cause major problems in
multilayer boards and can even snap the barrels of  a plated through hole!

There was such an oven in a place I used to work, they used to leave the
boards in over night and the temperature was not excessive - I'd guess about
40 deg Centigrade. you could handle the boards straight out of the oven
without burning - on the warm side of hot

hope this helps.
