Design of Printed Wiring Boards PWB Interconnection Models Signal Integrity and EMC Considerations... [Pg.1259]

This chapter outlines the basic considerations, the main choices, and the potential tradeoffs that must be accounted for in the selection of the interconnection methods for electronic systems. Its main emphasis is on the analysis of potential effects that the selection of various printed wiring board types and design alternatives could have on the cost and performance of the complete electronic product. [Pg.39]

A basic understanding of material performance is necessary for both the designer and fabricator of the printed wiring board (PWB). Understanding the materials available is one of the primary tasks for designing for manufacturability and performance. It is necessary to match the product end-use performance requirement as well as the environmental exposure the board experiences in the fabrication and circuit card assembly (CCA) processes with the capabilities of the material. It is common for boards to experience as many as five thermal excursions in CCA. [Pg.617]

Tin-lead and lead-free (Sn95.5Ag3.8Cu0.7) solder pastes were printed on printed wiring boards with various BGA and CSP design features. After paste printing, the boards with tin-lead and lead-free solder pastes were subjected... [Pg.237]

The release agent layer is used in ultrathin, printed wiring boards to facilitate removal of the carrier film fi om the very ultra thin metal layer. In order to avoid the problem of picking, which results in incomplete transfer of the very ultra thin metal foil to the substrate under lamination, the release agent layer is designed to peel at the interface between the parting layer and film carrier. The parting layer is... [Pg.214]
