Chip bonding

The use of bare dice offers many advantages compared to conventional components such as Surface Mounted Devices (SMD). Chip bonding refers to a technique by which the individual chips of a wafer are attached to a substrate using an appropriate adhesive.

Our technologies
  • Chip-on-Board (COB)
  • Flip-Chip
  • Chip-on-Glass (COG)
  • Chip-on-Metal (COM)
  • Chip-on-Flex (COF)
  • Chip-on-Ceramic (COC)
  • Die Stacking
Advantages of using bare dice
  • Miniaturization through size reduction
  • Reduction of contact points and thus improved reliability
  • Very good thermal adaptation to (ceramic-) printed circuit board
  • Hermetic seal possible (plastic components can absorb moisture and release it again inside a casing)
  • Exact population of semiconductor optical transmitters and detectors
  • Reduced thermal resistance of semiconductors on heat sink, as a transition point is omitted (e.g. LEDs with p- and n-up can be directly packaged on a heat sink)
Technical parameters
  • Size of bare dice: 0.25 mm to 80 mm
  • Die picking from wafer, blue foil or waffle pack
  • Application of conductive adhesives by: Silk-screen printing, dispensing or stamping
  • Eutectic soldering of power semiconductors in a vacuum or hydrogen atmosphere, without flux
  • Application of solder paste to a printed circuit board (printed, dispensed or through solder preforms)
  • Exact positioning of bare dice (series: approx. 0.012 mm in relation to a benchmark structure or circuit carrier reference of the printed circuit board, small quantities < 0.005 mm, for special applications up to 0.001 mm )
  • Flip-chip population
