Comments:
  • The mask layouts will be reviewed in IC station prior to making. During this review, necessary flash count for each mask plate is determined.
  • $250.00 for first 2500 flashes, plus $100 for each additional 2500 flashes, all per one mask plate.
  • Special Note: Maximum allowable number of flashes per mask plate is 15000.
