Multilayer PCB

A Multilayer PCB (Printed Circuit Board) is a type of circuit board composed of multiple layers of conductive copper foil separated by insulating materials. It typically includes three or more conductive layers interconnected through inner layer vias. The design of multilayer PCBs allows for complex circuit interconnections in a compact space, enhancing performance and reliability.

Multilayer PCBs are widely used in the following fields:
Communication Equipment: Such as 5G base stations, routers, switches, etc.
Consumer Electronics: Such as smartphones, tablets, laptops, etc.
Automotive Electronics: Such as car navigation systems, autonomous driving control systems, etc.
Medical Devices: Such as medical imaging equipment, life support systems, etc.
Aerospace: Such as navigation systems, satellite communications, etc.
Industrial Control: Such as factory automation equipment, robot control systems, etc.

The high-frequency board models commonly used by XCE’s customers include but are not limited to:

Manufacturing Challenges of Multilayer PCB
The main challenges in manufacturing multilayer PCBs include:

Layer Alignment: Precise alignment of the layers is crucial to ensure accurate electrical connections.
Thermal Management and Material Selection: Different materials have different thermal expansion coefficients; appropriate materials and effective thermal management are necessary to prevent layer separation and warping.
Hole Metallization: Even plating of the inner layer vias is required to ensure good electrical connections.
Impedance Control: Especially in high-frequency applications, precise control of line impedance is essential to maintain signal integrity.
Testing and Inspection: Multilayer PCBs require thorough electrical testing and visual inspection to ensure functionality and quality.
