Controlled impedances of printed circuits

frequencies, great care must be taken in designing the tracks to match the impedance of the upstream and Technical documentation 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

Printed circuit soldermask

have different colors: green, red, blue, white, black. Only the outer layers need to be covered with solder mask, the inner copper layers are protected by the adjacent substrate layers. The soldering mask soldermask is made documentation Technical of a fluid substance like an ink and is applied in a thin layer similar

Printed circuit board silkscreen

available: yellow, black, Technical documentation blue, red. Screen printing is used to render 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 printing does not influence the printed circuit and the possible problems that may appear
