Designing a PCB starts with the circuit, but the days when the substrate material is an afterthought are long gone. Performance rests on the design’s mechanical, electrical, and thermal considerations, and substrates lacking one or more of these areas are likely to exhibit poor quality and reliability over the device’s service life. FR4 is an…
An inherent risk when working with medical devices extends beyond general electronics concerns: defects and performance issues are more liable to cause personal injury. Given the possibility, medical manufacturing must strive for a higher standard than the general industry. ISO 13485 certification is the answer: by providing a foundation for exceeding competency goals while carefully…
Outside of video games, shortcuts and corner-cutting have a more negative connotation. We tend to view shortcuts as cheating, whether the person performs the action or the recipient. Typically, a shortcut invokes risk, which might momentarily solve a problem but lead to issues in developing knowledge or skills that can later undermine the shortcut user.…
The Association Connecting Electronics Industries (IPC) publishes the industry standard for PCB manufacturing—IPC-A-610. It is a comprehensive document that outlines the criteria and requirements for the acceptability of electronic assemblies, guiding manufacturers on quality assurance and inspection processes. The standard lists three classifications of PCB manufacturing requirements: Class 1, 2, and 3. Frequently, designers may…
Any electrical system with considerable speeds or sensitive/aggressive lines must keep EMI as a primary concern. Systems can experience poor or intermittent performance due to noise-induced signal distortion without carefully placing components, traces, and cables. While there are numerous methods to prevent EMI, one of the simplest and most efficient methods is twisted wire pairs…
For decades, Moore’s Law was a defining experimental rule defining the rate at which the customer demanded significant improvements in computing power and how fast manufacturers were able to furnish this request.
