 Carefully place all SMT components on the board.  Then "bake" the board in the reflow oven.  Our oven is pre-set for a Tin-Lead profile.  Plug it in. Place your board as near the centre of the oven as possible, then press the right button.  At the peak temperature, once the heat turns off, open the door to allow faster cooldown.  Watch the temperature! It's too hot to handle for longer than you might think.

+Erik's smt stencil etching method
+(more involved, but optimized for quicker etching time)
+Steps 1-6 as before
+  - select all→right click→clone→3columns,1row
+  - select Leftmost board, edit width to be 0.1mm (toolbar on the left) (make sure "lock" aspect ratio is OFF)
+  - same as above, but with Rightmost board
+  - select all→right click→Scatter Group
+  - select all→right click→fill, Direction: X Double, 508, 0, CHECK “Delete Contours”, OK
+  - zoom in to a small pad to check dpi setting - if lines are too far apart to get all the detail, increase scan dpi - if dpi is very high, it will take longer to etch
+  - if you decreased the dpi you may have to unfocus the laser and increase the power
+  - set velocity to 800 (it will go as fast as it can) and power to 30%
+  - carve out
