PCB design - stencil and soldering

Here is the stencil. He paid $10 for it when he got the PCB made. He uses a credit card to squeegee solder paste via the stencil, then it is into the reflow oven.

I asked about the masking tape as a spacer between the stencil and the board. He says it doesn't matter because he is using big parts and pressing down hard. Presumably if he was soldering a fine pitch microcontroller or such he would not want the tape spacer.

And more:

The finished board

In the oven.

He shows a later image with the oven at 245.78C after 7:47 that he calls "Oven at reflow".

And here we are, all done.
