How to Protect a Circuit From ESD

So you’ve submitted your board for ESD testing and let the smoke out of something.  Now what?  Finding a remedy for ESD, or electrostatic-discharge, problems can be a delicate balance between protection, functionality, and cost.  While there is no “one size fits all” solution for ESD, we’ve compiled the following sources of technical information to aid you in your quest to solve this complex issue.  Whether you’re designing an ECU for a car, a charging circuit for a cell phone, or a high voltage electronic device, you will find something useful in the contents below!

A veteran of the semiconductor and electronics industry, Mel began his career repairing dot matrix printers in 1998 for a larget IT company in the healthcare space. While earning his electronic engineering degree, he worked at a small design firm, giving him a broad base of knowledge in mechanical and electrical engineering, as well as purchasing and supply chain management. Once he graduated, Mel decided to pursue technical sales, working for one of the largest broad-line electronic component distributors in the world. To narrow his focus on a group of suppliers and technologies, Mel spent eight years working as a manufacturers’ rep selling semiconductors. With a well-rounded background in engineering, distribution, and technical rep sales, he currently works for a large semiconductor manufacturer in the Atlanta area. Mel has two small children and enjoys hiking on the weekends.
