Should the reference (i.e., ground) plane be split into two separate sections and a ferrite bead installed between them to prevent unwanted radio frequency emissions? Let’s examine why this practice is not a good idea and should be avoided at all costs.
This article provides insight into how shielding is used in product development, in particular the effectiveness of shielding when it is applied at the PCB level.
Low-cost designs are often an underserved and challenging part of a layout engineer’s career and getting increasingly complicated.
There are several scenarios where integrated circuits (ICs) are mounted on printed circuit boards (PCBs) which might be charged-up and experience CDM-like events.
Although the foundation of a failure analysis is rooted in science, there is also an art to completing one, successfully. The path from “problem discovery” to “problem solution” has many bumps and twists along the way and this article will hopefully help guide you on your journey.
The paper discusses the importance of understanding the current distribution below a printed circuit board trace.
Isola Group S.a r.l., a market leader in copper-clad laminates and dielectric prepreg materials used to fabricate advanced multilayer printed circuit boards (PCBs), announced a major qualification win in pa... Read More...
For Height Restrictive Applications, Global Connector Technology’s New USB3.0 Mid Reverse Connectors are the Perfect Choice
Global Connector Technology (GCT) has introduced a new range of USB3.0 mid reverse connectors that are ideal for inclusion in devices such as tablets, notepads and other hand held devices. In low profile applic... Read More...
The board stackup is probably the most essential piece for ensuring a successful PCB design. Modern high-speed busses require controlled-impedance traces, and whether you are using a simulation tool, a simple calculator, or the back of a napkin, you need to understand your manufacturing process to correlate your impedance calculations. This ensures that your trace widths and dielectric heights match what will actually be manufactured, and eliminates last-minute design changes.
Almost every electrical device has a physical structure that contains transmission lines. We call this structure a printed circuit board (PCB). There are three basic structures-rigid, flex and rigid-flex. Advan... Read More...
