FR4 OSP Surface Finishing Process
A Multilayer Printed Circuit Board (PCB) is a sophisticated assembly consisting of three or more conductive copper layers laminated together under high pressure and heat, with insulating materials (such as core and prepreg) separating each layer. Unlike single-sided boards, this complex structure enables high-density wiring and superior signal integrity.
Main Advantages of Multilayer PCB:
| 1. Enhanced Signal Integrity | • Separates signal layers from power/ground layers, reducing crosstalk between adjacent signal traces. • Provides a dedicated reference plane (ground or power) for signal layers, minimizing signal reflection and transmission loss. |
| 2. Higher Component Density & Space Savings | • Allows routing of traces on four layers instead of two, enabling more complex circuit designs in a smaller board area. • Reduces the need for through-hole vias or jumper wires, making the board layout more compact and suitable for miniaturized devices. |
| 3. Improved Electromagnetic Compatibility (EMC) | • Dedicated power and ground layers form a stable "power-ground plane capacitor," filtering out high-frequency noise. • Isolates sensitive analog signals from noisy digital circuits by placing them on separate layers, reducing electromagnetic interference (EMI) emissions and susceptibility. |
| 4. Cost-Effectiveness for Complex Designs | • More economical than 6-layer or higher-layer PCBs when basic 2-layer boards cannot meet performance requirements. • Lowers overall system costs by reducing the need for additional external components (e.g., noise filters) that compensate for poor signal or EMC performance. |
How to order multi-layer boards?
Send us your customizable Files:
1. Gerber files (RS-274X)
