Printed circuit board assembly
production and assembly of printed circuits are automated. Electronic computer aided design software is available to do much of the layout work. Multilayer PCBs allow for much higher component density because the board circuit base Aluminum printed component paths on the inner layers would occupy the space between the components. The increase in the need for multilayer printed
Printed circuit board silkscreen
has the role of a reference indicator for the components on the PCB. Graphics and text on a circuit board's PCB are usually printed with a non-conductive permanent epoxy ink. The color is usually white, although other colors are available: base printed board Aluminum circuit yellow, black, blue, red. Screen printing
Printed circuit board construction
divides the copper into separate conductive lines called tracks or circuit paths, pads for connections, metallized holes (vias) for passing connections between layers of copper as solid conductive areas Aluminum board printed base circuit for electromagnetic shielding or other purposes. Each of the conductive layers is designed with copper tracks (similar
