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

Evaluate Wire for Damage

• Evaluate any damage of wire outside of the glass
  bead during the fusing process
• No damage has been detected
• Further testing will follow
• Also evaluating the cleanliness of wire after the
  production process

Production and Wire Analysis Results

• Actual Wire Joints produced - 4606 single, 270
  double
• Planned Wire Joints - 6500 single, 600 double
• Second wire joint station online in November 2000
• Production goal 120 to 150 daily
• Wire meets specification based on our testing
• More studies on cleanliness after production
