With an estimated 80,000 SMTP lines in use standards are a lifeline for line operators and equipment and software developers worldwide. SEMI is developing a suite of standards for SMT and PCBA...

With this presentation, attendees will learn how materials matter in the 5G-world. From rigid laminates, copper styles and properties, flex materials, sintered paste OrMet for any-layer vias: all...

Circuit boards for the IoT world (Internet of Things) are often driven by the need for low power dissipation, low cost (which drives very low layer count), moderate to high-density and mixed-signal...

Signal degradation on PCB transmission lines manifests in many forms: undershoot, overshoot, ringing, pulse shape distortion, switching noise, attenuation, ground bounce, skew, etc. All these can be...

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...

This comprehensive seminar of how to design a PCB stackup to optimize performance while attaining the lowest cost possible. With the advent of very high-speed signaling along with multiple very...

This session is intended for board designers to understand the things RF engineers request during PCB layout. Experienced RF engineers will likely not learn anything new from this course, as the...

What is a wire? At high speeds, it behaves very differently from what we were taught in college. This presentation on high-speed basics makes the subject intuitive in a way that’s easily understood....

Supply voltages decrease with every new silicon generation, contributing as well to the goal of reducing power consumption of our electronics. Coupled with the resulting shrinking noise margins for...

This presentation will present a simple EM physics and geometry-based approach to designing power distribution networks on PCBs. From input power connection to the IC die, the simple rules discussed...

When time-varying (AC) signals travel in the transmission lines of a board, state-changing electric and magnetic fields are present. These fields, when not controlled, are the source of noise and...

How do you design a high-speed digital circuit with enough bypass caps in the right area to supply all the peak power demands? You can’t listen to all the expert advice because it seems they can’t...

Understanding millimeter-wave (mmWave) concepts can benefit RF designers, high-speed digital circuit designers and fabricators. In the RF industry, as frequency increases many circuit properties...

The material presented will be focused on the physics of electromagnetic energy basic principles, presented in easy-to-understand language with plenty of diagrams. Attendees will discover how...

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...

When creating libraries, standards are crucial for maintaining consistency, accuracy, and reliability. Yet, even with rigid standards in place, mistakes inevitably creep into such a detail-oriented...

The objective of this tutorial is to guide design teams through the process of evaluating and selecting the right laminate for a design, creating PCB stackups that meet the requirements of complex,...

As most engineers and designers are aware, EMI occurs because some mechanical structure, within or attached to our system, is capable of resonating and radiating electromagnetic field energy. Those...

Have you ever had a noise-sensitive circuit and tried to find the noise source? Even after you completely encased sensitive portions in all sorts of shielding, you still had noise? It’s very...

Raise the shields, Scotty! Starting with some simple definitions for ESD/EOS, this session describes the important differences in the energy involved and the type of damage that can result. The...

A step-by-step guideline for determining the PCB design requirements based on device energy consumption requirements. Wave cycle times and transmission line capacity form the basis of this...

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...

Tired of failing EMC certification over and over? Join the crowd. Shrinking IC geometries and a resulting increase in switching speeds make designing compliant printed circuit boards more...

With the advent of ICs with multiple power rails at very high currents, the design of the power delivery system in a modern product is often more difficult than routing the PCB to ensure good signal...

The new IPC Digital Twin standard (IPC-2551) defines an interoperable framework in which thousands of applications from multiple sources work seamlessly together, providing the opportunity for...

This is a session for embedded engineers and PCB designers who have never done RF board layout but are curious and want to have a go at it. It is not for experienced microwave engineers. This...
