The Butterfly Effect in PCB Design: Optimization of High-speed Lines for an FMC Carrier Board

When signals start to get affected by the physical characteristics of the PCB, things start to get a little tricky. A simple point-to-point connection won’t be enough to keep the integrity of the... [more]

Manufacturing by Design is the New DfM

Today’s SMT and PTH assembly processes are driven by component packaging technology and functional design requirements. These requirements are driving manufacturing/test toward “build right” and... [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]

Differential Pair Routing for SI and EMI Control

Differential pairs have been used in PC boards for years to carry high-speed serial and high-speed parallel data, in a variety of bus formats. Many board designers and engineers believe the rules... [more]
