New materials and build‐up constructions for advanced rigid‐flex PCB applications

Abstract

Purpose

This paper aims to explain how the goals have been met to manufacture rigid‐flex printed circuit boards (PCBs) in equipment used for rigid PCBs by utilizing new materials and process combinations.

Design/methodology/approach

A discussion of the technology and applications.

Findings

The main drivers for PCB technology have been size reduction, increased resolution, improved high frequency performance together with increased reliability and cost savings. To reach higher packaging density at the PCB level, Aspocomp has developed the technology with embedded active and passive components. However, in higher packaging density applications, the PCB‐technology has to offer more flexibility to PCB‐designers in order to effectively utilize space inside the electronic devices. Different flexible PCB solutions are needed to achieve this goal.

Practical implications

For fabricators of rigid PCBs there are challenges in production to adopt the new industry requirements.

Originality/value

This paper is of value to those involved with or interested in PCB technology.
