smaller and lighter equipment that has allowed them a high degree of development and effectiveness. Today, in our house, almost every electronic device that helps imprimat circuit us in the household contains a larger or smaller printed circuit: refrigerator, vacuum cleaner, television, but also for general use: telephone, computer.
circuit imprimat layer of the PCB and has the role of a reference indicator for the components on the PCB. Graphics and text on a circuit board's PCB are usually printed with a non-conductive permanent epoxy ink. The color is usually white, although other colors are available: yellow, black, blue, red. Screen
laminated on and/or between layers of conductive substrate sheets. A printed circuit board can have several imprimat circuit layers of copper which are almost always arranged in pairs. The number of layers and the designed interconnection between them (vias, PTHs) gives a general estimate of the complexity of the
