Printing Techniques

PRINTUP INSTITUTE provides experts and/or equipment dedicated to printing electronic components. The platform is open to all types of collaboration or service provision, for both academics and companies. After an in-depth feasibility study of the projects, services can be provided on an ad hoc or permanent basis, from one hour to a week.

Capillary printing >> HUMMINK NAZCA

The NAZCA printer allows the implementation of innovations requiring sub-micrometre resolution printing (line printing between 50 nm and a few microns): nanometric electrodes, graphene-based transistors for artificial neurons, customisable connectors for quantum circuits, packaging, etc…

A liquid-filled nanoscale pen (nanopipette) is attached to a macroscopic resonator oscillating at its own frequency. Deposition takes place continuously by capillary action, without any external energy source. The movement of the system adapts to the specific characteristics of both the ink (notably its viscosity) and the substrate. This process enables any liquid material to be deposited on any surface, with unprecedented resolution and design freedom.

  • Minimum track width: 20 nm
  • Spatial resolution (X, Y): ± 25 µm
  • Print area: 20 mm x 20 mm
  • Substrate thickness: 0.1 to 30 mm
  • Accuracy: 1 nm
  • Deposition speed: 100 micrometres per second
  • Printed layer thickness: less than 0.1 micron
  • Ejection nozzle size: 0.1 to 10 microns
Screen printing >> DEK 248

The DEK 248 printer is an easy-to-use semi-automatic device for the production of relatively small quantities of devices in a reasonable time, for products requiring a resolution of over 100 µm. It meets the needs of manufacturers who wish to print and characterise all kinds of components (e.g. electrodes, RFID antennas), and then produce them.

The DEKalign 4 vision system enables precise alignment to be checked before printing. This precision (> 100µm) ensures fine pitch printing, regardless of errors in PCB dimensions.

  • Print area: 508 mm x 508 mm
  • Minimum track width: ~ 200 µm
  • Ejection: Mechanical
  • Printed layer thickness: over 25 microns
  • Ejection nozzle size: 50 microns
  • Quantity of liquid required: ~ 10 ml
Inkjet Printing >> FUJIFILM DIMATIX DMP 2800

The DIMATIX DMP-2800 printer is an easy-to-use inkjet deposition system (high-frequency piezoelectric ejection of 2.4 pL drops) for prototype design and sample production.

Typical minimum resolution is around 50 µm.
Provided a solution or suspension has the right rheological parameters (viscosity of 4-8 cps and surface tension of 28-32 dyne/cm), it is possible to supply consumable material at reasonable cost for printing onto virtually any surface less than a cm thick (plastic, glass, ceramic, silicon, membranes, gels).
A minimum volume of 3.5 ml of ink is required.

  • Print head with 12 simultaneous nozzles
  • Spatial resolution (X, Y): ± 25 µm
  • Print area: 210 mm x 315 mm
  • Substrate thickness: 0.1 to 25 mm
  • Piezoelectric ejection
  • Printed layer thickness: less than one micron
  • Viscosity range: 20 to 5,000 cps
Ink dispensing >> KELENN TECHNOLOGY DMD100

The DMD 100 printer is designed for laboratories and prototyping of sensors, RFID antennas, flat batteries or functional plastic devices.

The DMD100™ is a deposition system equipped with one or two nozzles dispensing functional fluids on flat surfaces up to 40 mm thick. Ideal for dispensing fluids with viscosities in excess of 100 cp, resolutions of around 100 µm can be achieved, depending on the material deposited and the substrate. The equipment includes 2D multi-layer design and printing software.

  • Machine resolution (X, Y): ± 5 µm
  • Minimum track width: 30 µm
  • Print area: 200 mm x 200 mm
  • Substrate thickness: 0.1 to 60 mm
  • Reservoir volume: 0.1 to 5 ml
  • Printed layer thickness: less than 10 microns
  • Ejection nozzle size: 50 to 500 microns
  • Viscosity range: 20 to 5,000 cps
Vacuum thermal evaporator >> ALLIANCE CONCEPT EVA300

The EVA300 frame enables the production of high-quality thin films with reduced cycle times. It is a PVD thin-film deposition frame for R&D purposes.

Its main assets are robustness, scalability and compactness. The originality of this system lies in the “box coater” design of its vacuum chamber, which can be configured for either vacuum evaporation or magnetron sputtering.

Chamber dimensions 300*450 mm.

Photonic sintering >> XENON X-1100

The X-1100 system is a tabletop research tool that offers researchers a unique photonic technology for delivering broadband, high-intensity light. This technology enables printed ink to be sintered without affecting the substrate on which it is deposited.
