Rigid-Flex boards are printed circuit boards that are formed by areas of rigid parts made of FR4 material linked together with areas of flexible parts made of polyamide material with different thicknesses.
for connections, metallized holes (vias) for passing connections between layers of copper as solid conductive areas for electromagnetic shielding or other purposes. Each of the conductive layers is designed with copper tracks (similar to wires on a flat surface) that provide electrical connections on that board Rigid-Flex conductive layer. Another manufacturing process adds plated or metallized holes
the board and glued to the pads on the other side. "SMD" components are soldered on the same side Rigid-Flex board of 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
The inscription of the printed 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 board Rigid-Flex circuit board's PCB are usually printed with a non-conductive permanent
