Ideal for monitoring, diagnostic, and therapeutic devices, they deliver consistent performance and reliable quality for critical applications.
- Enhanced wiring capacity: The 4-layer structure allows separate power, ground, and signal layers, reducing crosstalk and improving signal integrity, suitable for medium-complexity circuits in communication devices and industrial control systems.
- Reliable solderability: The OSP film is easily removed during soldering, ensuring good solder wetting on copper surfaces, minimizing cold solder joints, and adapting to precision components like QFP and BGA.
- Superior light-shielding and protection: The black solder mask effectively blocks light interference in sensitive circuits and isolates the board from external environments, boosting corrosion and abrasion resistance.
- Cost-effectiveness: Compared to higher-layer boards, the 4-layer design balances performance and cost; combined with low-cost OSP and economical black ink, it offers controllable production expenses, suitable for cost-sensitive mid-complexity applications.
- Environmental friendliness: The OSP process uses non-toxic organic compounds, and the black ink is generally eco-friendly, complying with environmental regulations and reducing hazardous waste.
- Dimensional precision: The thin OSP layer and black ink do not significantly affect the board’s thickness or flatness, maintaining precision for high-density 4-layer circuit designs.
Core Challenges in Manufacturing Medical-grade PCBs
1.Strict medical standards compliance, including IPC Class 2, requiring full process traceability and zero-defect control.
2. High-precision requirements for fine lines, tiny vias, and tight tolerances, leaving almost no room for production errors.
3. Stable performance of high-TG, heat-resistant and reliable materials, with consistent quality in mass production.
4. Complex ENIG surface treatment, ensuring uniform thickness and strong bonding for long-term durability.
5. Comprehensive reliability testing, including electrical performance, thermal stress and safety verification.
6. Dense circuit layout and multilayer structure design, demanding advanced equipment and mature technical capabilities.
