Printed circuit board construction
(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 intaritura circuit cu imprimat flexibil a layer of copper foil, laminated to the substrate. Chemical etching divides the copper into separate conductive lines
Printed circuit soldermask
is applied in a flexibil intaritura imprimat cu circuit thin layer similar to varnish on the entire surface of the printed circuit less on the soldering pads and it also has a role of antioxidation of the copper traces. Being a substance with a high degree of electrical insulation, the soldering mask offers the printed circuit the
Printed circuit board assembly
than six layers of copper has been concurrent with the adoption of circuit imprimat intaritura cu flexibil surface mount technology. "Through holes" components are assembled by their legs passing through the board and glued to the pads on the other side. "SMD" components are soldered on the same side of the board. A board
