 + 
 +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.

 + 
 +Use part #41 which is an 8SOP with bottom vision test

 + 
 +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
