Sense Wire Procurement

Luma, Osram and Toshiba wires were evaluated Toshiba was considered the highest quality from initial

test Two pre-series of wire have been procured from

Toshiba Both have been evaluated One has been approved and is being used in production Full production order being submitted Audit of facility tentatively scheduled for Oct 2000

Evaluate Cleaning Effects

Evaluate the affects of cleaning the wire in ultrasonic cleaner after wire joint process

First evaluate any damage to the wire due to the cleaning

Second evaluate the effectiveness of the cleaning process

Samples were evaluated uncleaned, after 30 seconds, 1 minute, 5 minutes, and 10 minutes

30 seconds was found to be as effective as longer cleanings
