In the manufacturing of electronic products, printed circuit boards (PCBs) are an indispensable component. PCB boards can be divided into single panel, double-sided board, and multi-layer board. This article will focus on introducing the number of layers of PCB boards.
Single panel (PCB single-layer board)
Single panel is the simplest form of PCB board, with only one side covered with copper foil. Single panel is suitable for simple circuits such as electronic clocks, toys, etc. The production process of single panel is simple, the cost is low, but the function is relatively simple.
Double sided board (PCB double-layer board)
Double panel refers to a board covered with copper foil on both sides, which is connected through holes to complete the circuit. The production of double-sided panels is more complex than single panel panels, but easier to manufacture than multi-layer panels. Double sided panels are suitable for circuits of moderate complexity, such as audio systems, televisions, etc. The dual panel production is flexible, and components can be arranged on both sides of the board.
Multilayer board (PCB multilayer board)
Multilayer board refers to a multi-layer circuit board formed by one or more layers of insulating material between two copper foils. The production of multi-layer boards is more complex than double panel boards, but it can improve the density and performance of circuits. Multilayer boards are suitable for high-density, high-speed, high-frequency circuits, such as computers, mobile phones, etc. Multilayer boards can increase the number of layers as needed to improve the performance of the circuit.
According to the needs, PCB boards can be divided into single panel, double-sided board, and multi-layer board. Different types of PCB boards are suitable for different types of circuits and have different manufacturing processes and characteristics. Only by selecting the appropriate PCB board can the normal operation and superior performance of the circuit be ensured.
