gluing. provides reliable electrical connections between the component terminals in a controlled manner according to a predetermined scheme. Printed circuits are widely used in many fields: Consumer goods Military Aerospace Industrial Medical imprimat circuit un strat Naval The unprecedented development in recent years of all fields of activity has led to a revolution in the types
a flat sheet of insulating material FR4, Rogers or Polyamide for flexible circuits, and a layer of copper circuit imprimat strat un foil, laminated to the substrate. Chemical etching divides the copper into separate conductive lines called tracks or circuit paths, pads for connections, metallized holes (vias) for passing connections between layers of copper as solid conductive areas for
circuits, the inductance and capacitance of the printed circuit board conductors become significant, usually unwanted, circuit elements; rather, they can be used as part of the circuit un imprimat strat circuit design, as in distributed element filters, antennas, and fuses, avoiding the need for additional separate components. High Density Interconnect (HDI) PCBs have
