Abstract

Coating of functional materials is the basis of many electronic device manufacturing processes. Screen printing, roll coating and other methods have been used for decades, permitting low cost, high production rates of Printed Circuit Boards (PCBs), where conductive pathways are printed before components are integrated. Nowadays, the PCB industry in developed countries is suffering a revision of all manufacturing processes, to cope with severe market constraints: short runs and fast time-to-market. Inkjet technology has arrived to complement the traditional, analogical production, with new tools that makes possible to produce goods with great versatility.

In this work we will state the problem of inkjet printing functional materials in the frame of PCB manufacturing. The use of numerical methods to asset the formation of conductive pathlines using digital techniques will be presented. Also, the use of resistive and dielectric inks will be discussed.
