DATV-Express – video of "robots" building pre-production boards

Description:  The DATV-Express project was formed to create low-cost solution for Digital-ATV transmission. The open-source project was first announced and described at the TAPR Digital Communications Conference (DCC) in 2011.

In the video link below, four PCBA boards are being assembled by "pick-and-place" robot placing the SMT components onto the board. The blank PCBs are arranged as an 2x2 arrays. The robot arm spinning to the right location in order to lower the SMT component onto the correct footprint...and the board array underneath shifts so that the arm can reach all four boards. The SMT parts are held in place on the board by sticky solder "paste".  The next step is to place these DATV-Express boards onto a solder-reflow oven conveyor belt.
