[hpsdr] Penny Solder stencils

[Gerd Loch]

Hi Neal,

where are your problems?

Normally you solder first the solderside (where only capacitors and
resistors are placed) with this side up.
You can use hotair or a IR reflow oven. Then you assemble the component side
and solder it in the same way. The components on the solder side are then
upside down. Even if the solderpaste on the bottom side becomes liquid again
the components keep adherent through the solderpaste.

Manual assembly is normally done by me with a fine soldertip part after
part.

Gerd, DJ8AY

So, I have my Penny partial kit, the parts kit from John on the way, a good
supply of kester solder paste and Polulu mylar templates shipped today. I
kinda figured out that I will not be able to do both sides of the board with
a hotplate after I ordered the front and the back stencils but...

Does anyone have a recommendation on a good hot plate for this venture?
