Summary:

Helping designers to choose materials and other design criteria for optimal rigid-flex circuit manufacturability, cost effectiveness, and reliability, this reference thoroughly analyzes material, electrical, mechanical, and construction components of production.

Rigid-Flex Printed Wiring Design for Production Readiness details production procedures for commonly used designs, and explains the implications of choosing each design criterion. Special features that enhance the book's usefulness include step-by-step analysis of the Mil-P-50884 critical acceptance criteria ... glossary of rigid-flex terms ... and numerous tables, graphs, and diagrams that aid in predicting reliability levels. In addition, this volume addresses factors affecting serviceability of completed rigid-flex boards ... provides managers with decision-making tools necessary for introducing rigid-flex boards into products ... encourages management, design, production, and quality control staff to identify specific concerns to increase cooperation ... and focuses on designs for production readiness in order to eliminate costly modifications. Presenting accurate data for quick reference, Rigid-Flex Printed Wiring Design for Production Readiness is an indispensable guide for electrical and electronics, electronic packaging, assembly, circuit design, quality, and manufacturing engineers.
