Controlled impedances of printed circuits

taken in designing the tracks realizare cablaje imprimate to match the impedance of the upstream and downstream components. The longer the route or the higher the frequency, the better adaptation is required. When producing the printed circuit with controlled impedance, the impedance will be controlled by acting on the dimensions of the tracks and the distance between them,

Printed circuit board silkscreen

are available: yellow, black, blue, red. Screen printing is used to render useful information on the cablaje imprimate realizare PCB board that can help users during assembly. It is used to mark component values, part numbers, test points, polarity, etc. Screen printing does not influence the printed circuit and the possible problems that

Printed circuit soldermask

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 possibility
