| As an equipment vendor (Panasonic Create group)I am extremely interested in GEM/SECS. It is really a nebulous concept. Everyone I talk to wants something different but it's all lumped under GEM/SECS! I ask a simple question. What do you want it t

People often used direct current as a means to charge batteries and their electronic devices. They also use DC power for third rail power systems and railway propulsion. While DC means direct current, it also means constant polarity. Some types of DC will have variances in their voltage, while most will not. A good example of varying voltage would be fluctuating voice signals on a power line. One should never try to reverse the polarity in a DC device, unless it features a diode bridge that will allow for the switch. Most of the battery-powered devices that people use do not have this bridge, so trying to alter the polarity would actually destroy the device.

The board stack-up is probably the most essential piece for ensuring a successful PCB design. Modern high-speed boards require controlled-impedance traces, and whether you are using a simulation tool, a simple calculator, or the back of a napkin, you need to understand your manufacturing process to correlate your impedance calculations. This ensures that your trace widths and dielectric heights match what will actually be manufactured, and eliminates last-minute design changes.
