Kramer-Kronig’s Relationship to PCBs Kramer-Kronig’s Relationship to PCBs The Kramer Kronig relationship is basically a way to go back and forth from the real and imaginary parts of a function. That’s it. So when someone says “blah blah blah must conform to the Kramer-Kronig relationship”, it’s a statement that is stating the obvious. Similar statements are, dogs must be part of the canine family and thus canis genus or petrol must have come from petroleum deposit on earth. Both correct and mildly interesting Read Article
Long Range WiFi for Remote Sensors and Connectivity Long Range WiFi for Remote Sensors and Connectivity If you need to have network access from sensors which need more than a little bandwidth, cellular can get quite expensive. There are quite a few long-range wireless systems that are targeted towards sensors, however, trade bandwidth for range. If you need to stream video, send pictures, or have a constant stream of data from a range of sensors these wireless links might not be suitable. WiFi has rather limited range by comparison but does have Read Article
Requirements Management and Quality Functional Deployment Requirements Management and Quality Functional Deployment “Ending up in the wrong place is the result of bad directions, not bad driving. Product failure in the marketplace results from errors in requirements, not implementation.” - Thomas L. Musto, Chairman, IBM Corporation (Retired) A definition of QFD: Quality-Functional-Deployment (QFD) [literal translation of the Japanese characters] is an analytical method to help you transform customer needs (the voice of the customer [VOC]) into engineering Read Article
Changing PCB Reference Planes During Routing in Multilayer Boards Changing PCB Reference Planes During Routing in Multilayer Boards Vias with annular rings for reaching an interior PCB layer If you’re a new designer and you take a look at some boards in common electronic products, you may not even realize they are multilayer boards unless you know exactly where to look. The fact is that more complex devices simply do not allow every single trace to be placed on a surface layer, thus signals must be routed within an interior layer in order to make the desired connections. With Read Article
Why Doesn’t Every Application Use Rigid Flex Technology? Why Doesn’t Every Application Use Rigid Flex Technology? Why Doesn’t Every Application Use Rigid Flex Technology? Good Question! Rigid-flex technology is a hybrid between rigid boards and flexible circuits,m combing the most favorable aspects of both. The flexible portion helps solve space, weight, and packaging issues because it can bend, fold, and flex in either installation (flex to install) or end use (dynamic flex). The rigid portion supports dense component areas, allowing higher layer counts Read Article
PCB FR-4 Materials Are Not All The Same PCB FR-4 Materials Are Not All The Same In the PCB industry, “FR-4”.is a common designation for laminate materials. To a certain extent, FR-4 as a specific type of laminate is one of the many myths promulgated throughout the industry. This blog will address the history the term FR-4, what it really means, the various quantifiers associated with it, and the characteristic issues of concern when selecting design-specific laminates. The Origins of FR-4 If you research FR-4 as a term Read Article
Microvia Technology and Beyond for HDI Design Microvia Technology and Beyond for HDI Design HDI PCBs, ultra-HDI, packaging, substrate-like PCBs, and highly advanced chip-on-board can all require microvia structures once electrical connections become very dense. In these designs, higher density chipsets and packages have driven the demand for more advanced fabrication capacity that can support microvias into advanced stackups. But in addition to microvias in standardized HDI stack ups, there are more advanced interconnects available for Read Article
Scope Your PCB Design Data Management System for Success Scope Your PCB Design Data Management System for Success One of my favorite quotes from Zig Ziglar is “Success means doing the best we can with what we have. Success is the doing, not the getting; in the trying, not the triumph. Success is a personal standard, reaching for the highest that is in us, becoming all that we can be.” I like that - doing the best we can with what we have. I’d also add that to be successful with anything, we need realistic expectations and an understanding of precisely what Read Article
