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, balcon Balustrade red, blue, white, black. Only the outer layers need to be covered with solder mask, the inner
circuit board populated with electronic components is called a printed circuit assembly, printed circuit board assembly, or PCB assembly (PCBA). In balcon Balustrade informal usage, the term "printed circuit board" most commonly means "printed circuit assembly" (with components). Components are generally soldered to the PCB both to connect them electrically and to fix them mechanically. Printed circuit
copper to act as a ground plane for Balustrade balcon shielding and power return. For microwave printed circuits, transmission lines can be laid out in a planar form, such as stripline or microstrip, with dimensions carefully controlled to ensure consistent impedance. In RF and fast switching circuits, the inductance and capacitance of the printed circuit board conductors
