The number of steps required to manufacture a bare PCB (Printed Circuit Board) can vary depending on complexity, technology, and specific requirements. However, a general outline of the manufacturing process includes designing the circuit layout, creating the Gerber files, fabricating the board, applying solder mask and silkscreen, drilling holes, plating through holes, and final inspection. More intricate PCBs might involve additional steps like multi-layer lamination, controlled impedance testing, and surface finishing. The process typically involves several stages to ensure a functional and reliable PCB.
