This thing looks pretty crappy compared to assembleons machines. At my work we just got a MC-12 and the second machine in line for large components is a topaz-xII. The camera is on the robot and goes underneath the components for the MC-12, and the topaz has a camera similar to this one, but 8 heads. We make a board with 530 components on it in 103 seconds, the MC-12 does 435 small ones and the topaz does 95 large ones, for a graphics board. Or they do a board with 1273 small ones in 156 sec
How are optimized for speed the parallel load of all fingers and the motions of the arm if there are many different components scattered all over the board ?
I think the red strobe is for alignment. As you can see the the 5 nozzles pick up the components from the feeders, then the module moves to the centre of the machine and stops while the beam is flashed to check the rotation/alignment of all the components. After the check, all components that are aligned ok are placed onto the pcb and the ones that werent, are dumped. Then the machine will either have another attempt at placing or notify the operator that the component wasn't placed.
I'm pretty sure they don't drop components that aren't aligned. The pick and place head usually has little grippers that center the parts on the end. I believe that it is an infrared heater to heat the parts prior to placement, possibly to prevent the parts from falling off the board when it moves from machine to machine. Notice that there is a metal plate approximately the same size as the lamp that could prevent the rest of the head assembly from becoming overheated.
I meant it checks whether the nozzles (z-axis) has correctly rotated all components (e.g. if the component slipped and was being carried on it's end) and all components are actually present. The nozzles use vacuum to carry the components. This is how our smd pick and place machine works anyway.

sounds like a good beat of music going on there..:)

What does the red light strobe ?

surface mount dude, no cropping takes place. the infrared will be an optical centering system I would have thought.

I love these machines. Nice SEMI test.
