Copper Foil Lamination: Copper foil sheets are laminated onto both sides of the prepreg layers using heat and pressure. This forms the conductive layers (traces, pads, and planes) of the PCB.
Etching: A chemical etching process is employed to remove excess copper from the PCB surface, leaving behind the desired circuit traces and patterns as per the PCB design.
Plating and Surface Finish: Copper-plating processes are used to metallize the walls of the drilled holes, forming vias that establish electrical connections between different layers. Surface finishes such as immersion gold, HASL (Hot Air Solder Leveling), or OSP (Organic Solderability Preservatives) are applied to protect exposed copper and facilitate soldering during assembly.
Solder Mask Application: A solder mask layer is applied over the PCB surface, leaving openings (exposed pads) for soldering component leads and connections.
Silkscreen Printing: Identifying markings, component outlines, and other information are printed onto the PCB surface using a silkscreen printing process.
Testing and Inspection: Quality control processes including electrical testing, dimensional inspection, and automated optical inspection (AOI) are performed to ensure the PCB meets design specifications and reliability standards.
Final Fabrication Steps: After testing and inspection, the PCB panels are routed or scored to separate individual boards. Edge plating or other edge treatments may be applied as necessary.
