So, I fired up the reflow oven, and did my first "production" IMU board. I like the way it came out, although I had to fix a few solder bridges - I'm definitely going to invest in a solder mask stencil so I can apply solder to ten boards at a time, with very little time required. I can machine a jig to hold the boards in place without too much trouble, since the boards came indivually. These boards have very few components, so placing the components is fairly straight forwards once the solder paste is applied.
I also need to machine a jig to hold the board once it gets to this state, so I can solder the two sensor headers in place and ensure they are exactly perpendicular to the board.

What's you test procedure to make sure everything is where it should be and a proper contact is there for all pins ?

Hi Eric,
The procedure is (1) can I program the board (which checks for shorts between ground and +5, as well as all the programming pins), and (2) does it work? Working implies that the LED flashes on bootup, and that you can get reasonable values from the sensors when you ask over the bus. Once I get the surface mount stencils made, it will be much less of an issue, but I will still definitely be testing each board individually before they are sent out.
