Purpose – There has been increasing interest in the development of printable electronics to meet the growing demand for low-cost, large-area, miniaturized, flexible and lightweight devices. The purpose of this paper is to discuss the electronic application of novel printable materials. Design/methodology/approach – The paper addresses the utilization of polymer nanocomposites as it relates to printable and flexible technology for electronic packaging. Printable technology such as screen-printing, ink-jet printing, and microcontact printing provides a fully additive, non-contacting deposition method that is suitable for flexible production....

Advanced Organic Substrate Technologies To Enable Extreme Electronics Miniaturization.

Aug 14, 2014 | Susan Bagen, Dave Alcoe, Kim Blackwell, Frank Egitto.

High reliability applications for high performance computing, military, medical and industrial applications are driving electronics packaging advancements toward increased functionality with decreasing degrees of size, weight and power (SWaP) The substrate technology selected for the electronics package is a key enabling technology towards achieving SWaP. Standard printed circuit boards (PWBs) utilize dielectric materials containing glass cloth, which can limit circuit density and performance, as well as inhibit the ability to achieve reliable assemblies with bare semiconductor die components. Ceramic substrates often used in lieu of PWBs for chip packaging have disadvantages of weight, marginal electrical performance and reliability as compared to organic technologies. Alternative materials including thin, particle-containing organic substrates, liquid crystal polymer (LCP) and microflex enable SWaP, while overcoming the limitations of PWBs and ceramic.

This paper will discuss the use of these alternative organic substrate materials to achieve extreme electronics miniaturization with outstanding electrical performance and high reliability. The effect of substrate type on chip-package interaction and resulting reliability will be discussed. Microflex assemblies to achieve extreme miniaturization and atypical form factors driven by implantable and in vivo medical applications are also shown....

Resin Coated Copper Capacitive (RC3) Nanocomposites for System in a Package (SiP): Development of 3-8-3 structure

Oct 08, 2009 | Rabindra N. Das, Konstantinos I. Papathomas, Steven G. Rosser, Tim Antesberger, John M. Lauffer, Mark D. Poliks and Voya R. Markovich.

In the present study, we report novel ferroelectric-epoxy based polymer nanocomposites that have the potential to surpass conventional composites to produce thin film capacitors over large surface areas, having high capacitance density and low loss. Specifically, novel crack resistant and easy to handle Resin Coated Copper Capacitive (RC3) nanocomposites capable of providing bulk decoupling capacitance for a conventional power-power core, or for a three layer Voltage-Ground-Voltage type power core, is described....

Joule Heating Effects on the Current Carrying Capacity of an Organic Substrate for Flip-Chip Applications

Jul 22, 2009 | Varaprasad Calmidi, Irv Memis.

This paper deals with the thermal effects of joule heating in a high interconnect density, thin core, buildup, organic flip chip substrate. The 440 μm thick substrate consists of a 135 μm thick core with via density of about 200 μm. The typical feature sizes in the substrate are 50 micron diameter vias is the core/buildup layers and 12 micron thick metal planes. An experimental test vehicle is powered with current and the temperature rise was measured. A numerical model was used to simulate the temperature rise in the TV....

Reliability and Failure Mechanisms of Laminate Substrates in a Pb-free World

Apr 30, 2009 | Kevin Knadle.

This presentation surveys the most significant via and via-related laminate failure mechanisms from past to present using data from current induced thermal cycling (CITC) testing, failure analysis, and other sources. The relative life and failure modes of thru vias, buried vias, and microvias (stacked vs. non-stacked) are compared, along with the affect of structure, materials, and peak temperatures on the above. The origin of via-induced laminate failures such as "eyebrow cracks" and Pb free related internal delamination is also explored....
