+ | |||
+ | Install the tube so that it goes OVER the foam-padded bar and UNDER the unpadded bar | ||
+ | |||
+ | Place the tube so that the Phillips head screw is underneath the tube, this will help keep it in place. | ||
+ | |||
+ | Push the end of the tube all the way up to the metal stop plate. | ||

+ | ===== Program in chip feeder ===== | ||

+ | Use part #41 which is an 8SOP with bottom vision test | ||
+ | |||
+ | {{:mdcpickandplace:chipfeeder8soic.png|}} | ||
+ | |||
+ | Using the teaching camera, do your best to center the 8-soic part outline. The chips move a bit and we use bottom vision so this isn't critically important. Have the red dot indicate pin 1 - this will make it easy to program in the PCB parts orientation | ||

+ | When the chip is picked up it will do a 4-point bottom vision test | ||
