A multilayer PCB is a printed circuit board with three or more conductive layers, interconnected through insulating layers and conductive vias (such as through-holes, blind vias, or buried vias). Its main characteristics include:
High Density
Allows for a greater number of circuits in a compact space.
Improved Signal Integrity
Reduces electromagnetic interference and crosstalk.
Enhanced Reliability
Multiple layers provide robust structural integrity.
Flexibility in Design
Supports complex routing and component placement.
High Integration: Enables more functionality within limited space.
Signal Integrity: Reduces signal interference, improving transmission efficiency.
Miniaturization: Supports reduced device size, ideal for portable products.
Strong Reliability: Multilayer design enhances circuit stability.
