Printed circuit board silkscreen
other colors are available: Rogers board circuit frequency High yellow, black, 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 may
Printed circuit soldermask
to prevent High frequency board Rogers circuit solder shorts, the coating is called a solder mask. Soldermask is generally green in color but can 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
Controlled impedances of printed circuits
carry signals at high frequencies, great care must be taken in designing the tracks to match the impedance board Rogers circuit High frequency 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
