Purpose - The purpose of this paper is to look at innovation and the tension which arises between proprietorship and standardization. Design/methodology/approach - The paper presents an analysis of the learning curve theory in relation to the printed circuit board industry. Findings - The measurable impact of the learning curve will be different depending on a number of factors commonly found in the printed circuit industry - degree of process maturity/automation, run lengths, and presence of customized elements requiring modifications to process flow, materials, or procedures. Originality/value - There is no escape from continuing and inexorable downward price pressure from entrenched expectations and trends. A clear understanding of how these work will confer a competitive advantage to the strategist concerned with bringing innovative technologies to the marketplace.

Purpose - The purpose of this paper is to a provide short introductory overview of metal in board (MiB) circuit technologies for use in thermal management applications. Design/methodology/approach - The paper details the types of metal in printed circuit boards (PCBs) that are possible and the mix of key features each exhibits. These combinations offer a mix of capabilities in thermal management, current conduction, interconnect density, material usage and cost that can be chosen to suit a specific application. Examples of these board types and their uses are considered. Findings - Metal core and insulated metal substrate (IMS) PCBs are categories of PCB technologies which provide enhanced thermal management and current carrying capability. MiB technologies are based on conventional printed circuit materials and processes. This gives MiB a range of thermal and current handling characteristics which are particularly suited to a number of key existing and emerging applications. Research limitations/implications - Further research and development in materials, processes and designs will help broaden the applicability of these types of boards, enabling them to encompass even more thermal management applications. Originality/value - The paper shows that with 15 different types of metal core and metal backed PCB technologies available to handle thermal dissipation in power electronics, there is one to suit almost every application. This current and emerging portfolio of MiB types offers solutions which can handle thermal loads associated with power densities from about 0.25 W/cm2 to 10-15 W/cm2 and currents from 20 A up to approximately 1000 A. © Emerald Group Publishing Limited.
