Double-plated printed circuit board is a printed circuit with two layers of copper with metallized holes that can have a soldering mask or two soldering masks or it can be without a soldering mask and can have one or two silkscreen.
The steps that a two-layer board goes through in manufacturing are:
circuit, called serigraphy or silkscreen for short, is 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 2 Layer PCB circuit board's PCB are usually printed with a non-conductive permanent epoxy ink. The color
pads on the other side. "SMD" components are soldered on the same side of Layer 2 PCB the board. A board can use both methods for soldering components. Today PCBs with components mounted only through holes are now less common. Surface mount is used for components like transistors, diodes, IC chips,
Another manufacturing process adds PCB 2 Layer 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 of conductive substrate sheets.
