Blue Oil Medical PCB Printed Circuit Board With Gold Immersion Surface Customzied

Blue oil solder mask + gold immersion combination: The blue ink provides stable insulation and clear visual identification, while the gold layer on pads ensures reliable soldering performance, with strong adhesion and uniform thickness.​

Double-sided wiring structure: Supports bidirectional signal transmission, adapting to the circuit layout needs of standard electronic devices and satisfying small to medium-scale circuit design.​

Mature process integration: The combination of blue oil solder mask and gold immersion is stable, with good compatibility between materials, suitable for conventional production processes.

Excellent soldering reliability: The gold layer on pads has strong oxidation resistance and good conductivity, ensuring stable solder wetting, reducing the risk of cold solder joints, and being suitable for precision components like BGA and QFP.​

Clear identification and protection: The blue solder mask clearly distinguishes circuit areas, facilitating production inspection and fault diagnosis; it also effectively isolates the circuit from the external environment, enhancing corrosion resistance.​

Good high-frequency performance: The flat gold layer surface reduces signal transmission loss, making it suitable for high-frequency signal transmission scenarios in communication equipment and medical instruments.​

Cost and performance balance: Compared to some high-end surface treatments, it has relatively controllable costs while maintaining good performance, suitable for fields with certain requirements for precision and identification, such as consumer electronics and industrial control.
