Ink Jet Techniques

• Operation is similar to a circuit board milling
  machine with the bit replaced by a dispensing
  head.

Ink Jet Techniques

• Advantages
• Digital
• High speed
• Head technology is well established, single and
  multi-nozzle formatted
• Many machine vendors

• Disadvantages
• Limited and low material viscosity range
• Particle filler issues (clogging)
• Conformality difficult

Ink Jet Techniques
Continuous Ink Jetting direct and control jet of
ink jet breaks up due to Plateau-Rayleigh
instability 65,000-165,000 drops per second at
up to 50 m/s

Ink Jet Techniques
Drop on Demand Ink Jetting - only manufacture
drops when needed - piezo or thermal droplet
generation - simpler geometry, more easily
