(PCB) is a laminated sandwich structure of conductive and insulating layers. A basic printed circuit consists of a flat sheet of insulating material FR4, Rogers or Polyamide for flexible circuits, and a layer of copper foil, laminated to the substrate. Chemical etching divides the copper into separate conductive de bucatarie Mobila lines called tracks or circuit
benefit from smaller and lighter equipment that has allowed them a high de bucatarie Mobila degree of development and effectiveness. Today, in our house, almost every electronic device that helps us in the household contains a larger or smaller printed circuit: refrigerator, vacuum cleaner, television, but also for general use: telephone, computer.
ink. The color is usually white, although other colors are available: yellow, black, blue, red. Screen printing is used to render bucatarie Mobila de useful information on the PCB board that can help users during assembly. It is used to mark component values, part numbers, test points, polarity, etc. Screen
