👉 The term "overlayer" is a concept in electrical engineering that refers to a layer of material or component placed on top of another, such as a conductor. Overlayers are typically used in electronic circuits where the base conductor needs protection from external sources and can also provide additional functionality like insulation or signal routing. Overlayers are often made up of conductive materials like copper or aluminum, which is then covered with other types of materials like insulators or resistors to improve electrical performance or to add additional
