Surface Characteristics of Ink-Jet Printed Circuits by Polyelectrolyte Multilayers with Zone Model Analysis and Salt Solution Improvment
Abstract:This paper disclosed recent novel development in printing circuit on flexible substrate by combining self-assembled polyelectrolytes, inkjet printing of catalyst, and electroless plating of metal. Experimental results indicated that building up zone model would enhance substrate surface uniformity. The results also showed that salt concentration would dramatic change the polyelectrolyte layer property before ink-jet printing of catalyst. Salt ions would balance charges in polyelectrolyte layers and smear the surface. It made the finer diameter of porous hole and significantly increased the adhesion between the ink-jet catalyst and the substrate. Surface uniformity was controlled within ±5%. A high quality circuit fabricated by said ink-jet printing method is presented.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
