Abstract

Purpose

The purpose of this paper is to detail various aspects of laminates and their current developments in order to enable the selection and development of appropriate laminate systems for use in high performance avionics interconnection applications.

Design/methodology/approach

Electronic packaging must provide circuit support, heat dissipation, signal distribution, manufacturability, serviceability, power distribution and data for performance simulation over the required frequency range in avionics applications. Innovations in packaging technology have made a big impact on the types of laminates that can be used in printed circuit boards destined for these applications. The “environments” in which aircraft are required to operate have changed due to global security threats and the laminates traditionally used are not designed for this role. Aircraft systems are expected to withstand disturbances due to unexpected threats. Various factors which determine the performance of laminates are evaluated.

Findings

The safety of aircraft is critically dependent on the interconnection technology in which laminates have a major role. Under global security threats, passenger safety, emergency landing and timely information to the pilot is of paramount importance. Hence, research programs need to be initiated to develop new innovative laminate systems, since traditional laminates have limitations in these applications.

Research limitations/implications

The availability of data on the performance of laminates used in interconnection technology under various security threats is limited.

Originality/value

The paper describes how new laminates for high performance interconnection technology in avionics applications can be developed.

This paper aims to investigate and document the effects of copper-clad laminate (CCL) inorganic filler on the hole performance in printed circuit boards drilling process.

Abstract

Purpose

This paper aims to investigate and document the effects of copper-clad laminate (CCL) inorganic filler on the hole performance in printed circuit boards drilling process.

Design/methodology/approach

Drilling of brittle laminates can result in hole cracking, layer-to-layer delamination and drill-bit wear and tool breakage. Adding large amount of fillers not only shortens the life of the drilling tool but also affects the drilling properties significantly regarding hole quality. This paper introduces the influence of filler content, type, hardness, particle size and the compounding method in the manufacture of the CCL on the drilling performance.

Findings

The filler content, filler type, hardness of filler, particle size of filler and the compounding method used for the filler have a great influence on the drilling properties of CCL. The higher the filler content, the larger the particle size and the more the hardness of the filler, the worse the drilling properties. The combination of hard particles like silica with softer particles can improve the drilling performance of CCL.

Originality/value

The paper describes what affects the drilling performance of CCL and how this knowledge can be used to design CCL with good drilling performance.

Abstract

Purpose

The access to high quality, a reliable and affordable basic healthcare service is one of the key challenges facing the rural and semi‐urban population lying at base of the pyramid (BoP) in India. Realizing this as a social challenge and an economic opportunity (shared value), there has been an emergence of healthcare service providers who have bundled entrepreneurial attitude and passion with available scarce resources to design and implement cost‐effective, reliable and scalable market solutions for the BoP. The purpose of this research paper is to understand the underlying operating principles of these self‐sustainable business models aimed at providing healthcare services to the BoP segment in India.

Design/methodology/approach

The empirical context involves the use of case study research methodology, where the source of data is published case studies and the company websites of four healthcare organizations who have made a socio‐economic difference in the lives of the rural and semi‐urban population lying at the BoP in India.

Findings

The analysis and findings reflect the key operating principles for sustainable healthcare business ventures at the BoP. These include focus on 4A's (accessible, affordable, acceptable and awareness), local engagement, local skills building, learning by experiment, flexible organizational structure, dynamic leadership, technology integration and scalability.

Research limitations/implications

This research study has focused mainly on the published case studies as source of data.

Originality/value

The intent is to understand and bring forth the learning and guiding principles, which act as a catalyst for the future researchers and business ventures engaged in BoP context.
