Printed circuit soldermask
like an ink and is applied in a thin layer similar to varnish on the entire surface of the printed circuit less on the soldering pads circuit imprimat multistrat and it also has a role of antioxidation of the copper traces. Being a substance with a high degree of electrical insulation, the soldering mask offers the printed circuit
Printed circuit board construction
provide electrical connections on that conductive layer. Another manufacturing process adds plated or metallized holes that allow interconnections between layers. PCBs mechanically support electronic components using pads for bonding the component terminals and electrically connect them using traces of one or more layers of copper sheets laminated on and/or between layers
Types of printed circuit board
rigid printed circuit on an FR4 substrate. These printed circuits are used more and more lately, having the advantage of their flexibility. A PCB may have an inscription or screen printing that identifies components, test points or identification text. Screen printing does not normally affect the operation imprimat circuit multistrat of a PCBA.
