Our laser-based processes are compatible with many different substrate materials, ranging from low-loss polymers to high-temperature ceramics.
LED flasher circuit on alumina.
Most laser-machinable insulating ceramics are candidate substrate materials for miniature circuit fabrication using our technology. Demonstration circuits have been fabricated on polished alumina substrates by silver paste filling of laser-milled channels and pads. Attaching miniature IC’s and 0201 and 0402 passives resulted in a working circuit with dimensions of only a few millimeters.
LED flasher circuit on polyimide.
Through use of new electronic nanomaterials that allow high quality conductors to be deposited from paste and sintered at temperatures compatible with organic substrates, the embedded conductor approach can be extended to substrates like polyimide, liquid crystal polymer, ABF (Ajinomoto Buildup Film), and RCC (resin-coated copper)
The figure above shows an example of construction of the same LED flasher circuit on a polyimide substrate. In this example the circuit is mounted on a small, rechargeable Li battery only 7 mm in diameter.
