generally green in color but can have different colors: green, red, blue, white, black. Only the outer layers need to be covered with inscriptionare imprimat cu circuit solder mask, the inner copper layers are protected by the adjacent substrate layers. The soldering mask soldermask is made of a fluid substance like an ink and is applied in a
fixing the electronic components in designated locations on the outer layers by gluing. provides reliable electrical connections between the component terminals in a controlled manner according to a predetermined scheme. Printed circuits are widely used in many fields: Consumer goods Military Aerospace cu circuit inscriptionare imprimat Industrial Medical Naval The unprecedented development in recent years of all
rigid printed circuit on an FR4 substrate. These printed circuits are used more circuit imprimat cu inscriptionare 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 of a PCBA.
