When Should You Use a Flex Circuit? The two predominant reasons for using flex or rigid flex, are to solve a packaging issue or reduce the space and weight of the electronics package. These two are often interrelated and space, weight and packaging, (SWaP) will continue to be a driving force in PCB design. Read Article

Creating a Ground Plane for Your PCB Design It used to be that printed circuit boards seemed to have the same basic layer configuration, or at least that’s the way I tend to remember it. This meant that they were usually six layer multi-layer boards, with a ground plane and a VCC plane. The old CAD systems didn’t really have the ability to do much with power planes except to designate layers as a bottom layer or the like. The most you would see in them would be some “X’s” where there was Read Article

The Advantages and Disadvantages of Active and Passive RFID Technologies When I’m designing a new PCB or product one of the hardest parts for me is choosing exactly which components I should use. It seems like every technology out there now has a different configuration to achieve the best performance. Even when you’re dealing with a fairly straightforward technology like radio frequency identification (RFID) circuit board there are a lot of flavors to choose from. While every type of RFID design label uses an active Read Article

Circuit Design Tips: PCB Moisture Protection for Humid Environments I pride myself on being meticulous when I check my designs. I can spend hours checking schematics, footprints and the proper values of components before finalizing the design. Unfortunately, the same zeal and perfectionism cannot be said with my housekeeping skills. A cleaner would have been horrified by the accumulated dust in the corners of my house. It was particularly embarrassing when I forgot to wash my dish tray and it became the home to a Read Article

How to Use a Ferrite Bead in Your Design to Reduce EMI EMI can be a tricky subject. That’s why I’ve been writing about things like proper grounding, AC/DC circuits, high speed routing, and differential pair routing. Next on the list is how to reduce EMI using ferrite beads. Ferrite cores can be finicky, which is why it’s important to first understand the theory behind them. Most electronic components are essentially plug and play; however, ferrites have to be designed into your system. Once you know Read Article

Using ESD Grounding Techniques to Protect Your PCB from Electrical Damage I was in high school before I considered engineering as a career outside of the engine room on any Star Trek show. Although, subconsciously I was definitely interested in it. The signs were there early considering I could name all the chief engineers from Star Trek. The deal was sealed though when I was ridiculously excited to receive an ESD grounding wrist strap bracelet as a gift. Don’t have one in your jewelry box? Well, it’s composed of Read Article
