PCB Patch Technology in the Electronics Industry

• PCB, or printed circuit board, is a crucial electronic component that serves as a foundation for interconnecting electronic components and electrical devices.
• Any electronic device, from computers to small electronic watches, relies on PCBs to connect various elements.

Introduction to PCB Boards

The layers of a PCB primarily consist of the power layer, ground layer, and signal layer, with the total number of layers being the aggregate of each type. During the design process, the initial step involves coordinating and categorizing all power sources, grounds, and various signals, followed by deploying and designing based on this classification.

Designing Power Layers

The primary focus in designing the power layer is on the type and quantity of power supplies. For high power requirements, multiple power layers can be employed to supply power to devices across different layers.

Designing Signal Layers

The design of signal layers should reflect the characteristics of all signals involved. Signal density and the integrity of special signals are critical factors that must be addressed in layer design.

Considerations for Single or Double-Sided Boards

Designing single or double-sided boards may not be suitable for high signal density or complex signal structures. The absence of a dedicated reference ground layer in single-sided boards increases the loop area and radiation.

PCB Assembly Industry

• The PCB assembly industry primarily comprises a power layer, a ground layer, and a signal layer.
• Establishing proper layering and subsequent deployment and design operations based on this structure are key aspects of PCB design.
