Printed circuit board silkscreen
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 be slight discolorations due to the high temperatures for gluing the imprimat flexibil circuit components, so they are only PCB design problems.
Controlled impedances of printed circuits
must be taken in designing the tracks 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 imprimat circuit flexibil with controlled impedance, the impedance will be controlled by acting on the dimensions
Printed circuit board assembly
(with components). Components are generally soldered to the PCB both imprimat circuit flexibil to connect them electrically and to fix them mechanically. Printed circuit boards are used in almost all electronic products and some electrical products. Currently, the production and assembly of printed circuits are automated.
