* Control Boards, Pump Controllers, Interface Assemblies
• Several TFR’d parts
• Provided support for teammates TFRs
– Blue Phoenix aka Focus II Rider

Testing

13. 13
• Issue
– Pin 11 on chip U27 failing
• Problem Observed
– High voltage spikes seen on pin 11 above
rated tolerance are deteriorating it
• Potential Cause
– Higher voltages are being induced on pin 11
trace from a nearby high voltage trace
– Actuator runs and causes spiking from back
EMF
• Actions
– Unable to test HV trace properly and is almost
certainly the cause
– Test actuators to eliminate as a possibility
Testing Cont. – Cougar

14. 14
• As much work to support products after their release
• Length of time for bringing a new machine to market
• The most important question to ask “What’s the goal?”
