PCB Design and Assembly Process Strategy for High Density CSP, WLP, 2D and 3D Semiconductor Package Technology

Topics covered: 1. BGA/CSP process technologies and standards; single die BGA and FBGA packaging, flip-chip and die-size package technologies, wafer level packaging (WLP), fan-out wafer-level... [more]

Does a Differential Pair Need a Return Plane?

A differential pair is any two transmission lines. When each transmission line has a return plane, its pretty clear how the differential impedance is related to the geometry. But what if there is no... [more]

The Basics of PCB Design

Technical sessions at conferences often emphasize the latest techniques and technologies, but those classes are often too in-depth for a novice designer, and don’t speak to the questions from the... [more]

PCB Design of Power Distribution and Decoupling

Power distribution in PCBs is the foundation around which all things work in the circuit. If this is not designed correctly, the entire circuit is at risk from noise and signal integrity issues, to... [more]
