Printed Circuit Assembly Design

Chapter 2: Key Factors Influencing Design

Overview

There are many important, interrelated factors, considerations, and requirements that influence how printed circuit assemblies (PCAs) are configured. These include, but are not limited to

  • Application considerations. How the PCA will be used in the end product or system

  • Performance requirements. What the PCA must achieve, functionally

  • Interfaces. The relationship and interactivity within the PCA s final installation

  • Manufacturing and test compatibility. The ability to produce the design as reliable, cost-effective hardware

  • Cost and schedule constraints. Programmatic requirements associated with budgetary and delivery issues

This chapter serves as a guide to the various parts of this book by listing the sections that specifically address and discuss each of the factors that have a key role in determining how a PCA can be optimally configured.

2.1 Application Considerations

These include

  • Use and maintenance of the end product

  • The PCA s operating environment

  • Size and weight constraints

  • Accessibility, safety, and reliability requirements

  • Design standards
