Four-Layer Double-Sided Green OSP Board
Four-layer double-sided green OSP boards, using high-reliability FR-4 base material and environmentally friendly OSP surface treatment, the green solder mask layer conforms to the visual standards of mass production in the PCB industry. It can seamlessly adapt to the automatic production line's soldering and inspection processes, significantly improving the production efficiency of batch production. The organic protective film formed by the OSP process has high temperature resistance and strong oxidation resistance, can precisely avoid the risk of welding short circuits, and with the four-layer optimized layering design, realizes efficient isolation of power and signal lines, effectively reducing signal crosstalk, and ensuring stable transmission of medium and high-speed circuits. The product supports flexible customization of board thickness, copper thickness, and fine line specifications, is compatible with various packaging processes, has undergone strict environmental reliability tests, and is suitable for mass production scenarios in industrial control, consumer electronics, security equipment, etc. It is a high-quality PCB solution that combines high cost performance, stable performance, and environmental compliance.

Product Overview
A four-layer PCB provides additional routing options through its internal copper layers and outer-layer circuitry. It can support designs requiring more complex signal, power, or ground layouts. This product features a green solder mask and an OSP surface finish. The stack-up, board thickness, copper thickness, and impedance requirements should be confirmed against the customer's design files and engineering review.
Typical Applications
- Industrial control boards
- Communication and networking equipment
- Embedded control systems
- Electronic products requiring more complex routing
Key Features
- Four-layer construction provides additional routing capacity
- Signal, power, and ground layers can be arranged according to design requirements
- Green solder mask
- OSP surface finish
- Impedance requirements are determined by the actual circuit design
FAQ
Q: What are the advantages of a four-layer PCB over a double-sided PCB?
A: Four-layer construction adds routing capacity and more options for signal, power, and ground planning. The actual benefits depend on the stack-up, layout, and circuit requirements.
