1. Component Placement 1.1 Grouping Components When placing components on your PCB, it’s essential to group them based on their functionality and interconnectivity. This approach helps minimize the length of traces and reduces the risk of signal interference. For example, keep analog and digital components separated to avoid noise coupling. 1.2 Orientat ion and Spacing […]
What are Integrated Circuits? An integrated circuit (IC), also known as a microchip or chip, is a set of electronic circuits on a small, flat piece of semiconductor material, usually silicon. It is called an “integrated” circuit because the components, such as transistors, resistors, and capacitors, are fabricated together on the same substrate. Integrated circuits […]
