Image Circuit Wrap

CircuitWrap creates metal mesh films for flexible display technologies. Produced by capillary infill of polymer structures on glass or PET films, it produces metal mesh down to an ultra-thin grid-width for use in mini and micro-LED displays. Panel-makers and original equipment manufacturers (OEMs) can then produce foldable touch screen devices with different form factors.

Image Circuit Shield

CircuitShield powers the technology that produces smartphones with 5G capabilities. It is the ideal cost-effective solution for EMI shielding, creating an ultra-thin uniform coating with optimal sidewall coverage and high shielding effectiveness. Simply put, CircuitShield creates EMI shielding for electronics with high throughput and lower equipment costs compared to conventional sputter coating. CircuitShield inks provide 60dB- 80dB of shielding at 1 GHz with only 1-3um of film thickness. This is less than half the thickness required from less-conductive nanoparticle-based formulations.

Image Circuit Seed

CircuitSeed is a radically more efficient method for plating electronics – reducing a 20-step process to 8 steps and using 50 times less water. As a low-cost, flexible solution, it supports multiple chemistries that can be printed via a variety of techniques. For copper deposition, either electroless plating or electroplating can occur after the silver layer has been fully metallized.

Specifications

  • Curing profile
    • Drying: 120℃, 10 min
    • Annealing: 160℃, 30 min
    • Reduces water usage from 2000L/m2 to about 40L/m2
  • Additives
    • Organic base
    • Water-based polymer
  • Ability to tailor primary coordination sphere of nick ion with self-reducing ligands

Applications

  • 3D or conformal printing on complex shapes
  • TSV or TGV display (can print the ink and cure to create a conformal coat on high aspect ratio vias)
  • Low temperature substrates can also be accessed and directly electroplated after printing.
  • Compatible with lithographic chemicals and processes including plating
