of the first aids that allowed this modernization. The smaller and smaller dimensions and the imprimat dublu circuit placat flexibility of the printed circuit board made in recent years have greatly helped fields such as medicine and aeronautics to benefit from smaller and lighter equipment that has allowed them a high degree of development and effectiveness.
traces or unwanted electrical contact with possible loose wires. For its function of helping to prevent solder shorts, the coating is called a solder mask. Soldermask is generally green in color but can have different colors: green, red, blue, white, black. Only the outer layers need to be placat imprimat circuit dublu covered
the printed circuit, called serigraphy or silkscreen for short, is dublu circuit placat imprimat done on the top layer of the PCB and 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
