This paper is an in depth presentation of a novel approach for design and manufacturing processes to embed ceramic thick film resistors and discrete capacitors into circuit board substrates. These robust materials are available in a wide range of values. Embedded passives, i.e., resistors and capacitors built right into the printed circuit board substrate will be the next pivotal technology for the PCB industry, preceded by the plated thru hole in the 50s, and microvias in the 90s. Key drivers are performance, miniaturization, and cost. The average cell phone has 445 SMT passive components at a 25:1 ratio to ICs. Embedding many of these will improve performance, enable more functionality and reduce cost per function. Embedded passives are not limited to cell phones, many other applications will benefit from improved performance. Several materials are commercially available today and many new materials are in development.
