PRECISION DIE ATTACH

Typical Die Attach Structure & Specifications
  • Minimum distance between surrounding square of fiducial and neighboring objects must be 0.048 mm
  • Gray level contrast between background and fiducial must be a minimum of 100 gray levels out of 256
  • Background of fiducial must not have a structure and background must be single colored gray level
  • Max. die size for dipping: 50 mm x 50 mm
  • No waffle-pack handling for die < 1 mm2
