Fabrication of passive elements using ink-jet technology

Abstract Introduction MicroJet technology is an emerging technology developed to meet the needs of next generation electronic and opto-electronic packaging solutions in a data-driven manner. It is based on piezoelectric demand-mode ink jet printing technology that is capable of generating and placing droplets of polymers, solder, organometallic and metal nanoparticle solutions, 25-125µm in diameter, at rates up to 4,000 per second. As performance, real estate and overall system costs become critical in manufacture of printed circuit boards, ink jet printing is becoming an increasingly attractive material deposition method. Ink jet based deposition is a low cost (no tooling required), noncontact, flexible & data driven (no masks or screens are required since the print pattern is created directly from CAD information and stored digitally), and environmentally friendly (it is an additive process with no chemical waste)
