Printed circuit board silkscreen
users during assembly. It is used to mark component values, part numbers, test documentation Technical points, polarity, etc. Screen printing does not influence the printed circuit and the possible problems that may appear may be slight discolorations due to the high temperatures for gluing the components, so they are only PCB
Printed circuit board assembly
documentation Technical the component paths on the inner layers would occupy the space between the components. The increase in the need for multilayer printed circuit boards with more than two, four and especially more than six layers of copper has been concurrent with the adoption of surface mount technology. "Through holes" components are
Controlled impedances of printed circuits
printed circuits operating at frequencies above 200 or 300 Mhz. Impedance calculator software is a good starting point to determine the track width (w) and insulation thickness (h) of a given impedance. In terms of signal traffic in printed circuits, when the tracks carry signals at high frequencies, great care documentation Technical must be taken
