Product Details
FR4 OSP 4-layer board PCB
Product Description:
FR4 OSP 4-layer board PCB Multilayer PCB is a printed circuit board composed of three or more layers of
circuits. Each layer of circuits is composed of different circuit
layers, and these layers are connected together through vias or
interconnecting lines. Compared with single-sided and double-sided
PCBs, multi-layer PCBs can achieve more circuit wiring in a smaller
space and are suitable for more complex and function-intensive
circuit designs.
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. |
Product Features:
- Multi-layer design
- Inner layer and outer layer
- through hole
- Copper layer
- Dielectric layer (dielectric material)
Manufacturing process:
- Design and layout: During the design phase, engineers use PCB design software to lay
out and route multilayer circuit boards, determining the functions
of each's circuit and the interconnection method between layers.
- Lamination: During the manufacturing process, multiple circuit layers are
pressed together through a lamination process, with each layer
separated by an insulating material. lamination process is
typically carried out under high temperature and high pressure
conditions.
- Drilling and electroplating: Through-hole connections between different layers of the circuit
are formed by drilling technology, and then electroplating is
carried out ensure the conductivity of the through-holes.
- Etching: On each layer of the circuit, use photolithography and etching
techniques to form the circuit pattern, removing excess copper foil
- Assembly and welding: After the components are installed, they can be soldered and
connected using surface-mount technology (SMT) or traditional
through-hole technologyTHT).
