Bonding of dies and chips on both planar and flexible substrates (excluding sub-micron flip-chip)
Photonic, electronic and/or microfluidic dies (or chips) can be bonded together into multi-chip modules and other photonic assemblies. The underlying substrate can be a chip, a wafer, a printed circuit board or even a large roll-to-roll (R2R) foil. Die bonding is typically faster and less accurate than flip-chip bonding (see separate service card).
Die bonding at VTT in Oulu
Multichip Die Bonder, Datacon (Besi) EVO 2200, is a versatile and automated die attach tool that supports high-volume assembly. It has R2R capability and a bio dispenser. Contact person is Markku Lahti.
Die bonding at VTT in Espoo
Infotech die sorting machine in Micronova allows to pick-and-place dies and chips with high throughput. There is also a camera system to automatically image large areas.
FC 150 bonding tool in Micronova is an older flip-chip bonding tool that is not suitable for sub-micron flip-chip bonding, but it can be used for manual and semi-automated die bonding and flip-chip bonding with approximately 1 µm accuracy.
Contact person for both tools and related services is Giovanni Delrosso.
