Microchip's Web Seminars help you to learn more about our products without having to leave the office! This plane is commonly formed by a metal case or ground area on a PCB. Most fabricators can do 5 mil lines and 5 mil spacing, but 8 mil spacing is a typical minimum spacing used by board designers. Integrated and scalable, PADS allows individual engineers and designers to accomplish a wide breadth and depth of core PCB development tasks, including schematic entry, analog design, signal and power integrity, thermal analysis, and PCB layout-to-manufacturing HyperLynx Analog provides basic simulation capabilities, such as DC, frequency and time-domain analysis, as well as more statistical approaches such as Monte Carlo and multiple sweep analyses. Check out Microchip's new Inductive mTouch™ Sensing Solution. The ground plane acts as a counterpoise that forms the other 1/4-wave element, creating in essence a half-wave dipole. I went ahead and updated my references from IPC-D-275 to IPC-2221. This Javascript web calculator calculates the trace width for printed circuit boards based on a curve fit to IPC-2221 (formerly IPC-D-275). So while the area is based on a non-linear formula, the thickness has a basic linear scaling effect. Www.microchip.com/mtouch: The Inductive Touch Resource Kit contains application notes and reference designs (software examples and schematic) to get you started quickly. WebSeminar and learn the basic principles as well as sensor construction and operation.
