2 oz Copper ENIG Rigid-Flex PCB

Rigid-flex PCBs are widely used in medical devices, industrial control systems, consumer electronics, automotive electronics, and aerospace equipment. They combine rigid board areas with flexible circuit sections. This makes them suitable for compact products that need stable connections and efficient use of space.

A 2 oz copper ENIG rigid-flex PCB offers higher current carrying capacity than standard copper designs. It also provides good solderability and corrosion resistance. These features make it suitable for power circuits, high-reliability electronics, and demanding operating environments.

The manufacturing process includes flexible materials, multilayer lamination, ENIG surface finishing, and precise process control. Material selection and manufacturing quality directly affect PCB performance and long-term reliability.

2 oz Copper Thickness ENIG Rigid-Flex PCBs Offer Significant Performance Advantages

Highly integrated electronic devices have increasingly stringent requirements for PCB stability and space utilization.

• 2 oz copper thickness enhances current carrying capacity, making it suitable for high-power and high-density electronic devices.

• The ENIG (Electroless Nickel Immersion Gold) process improves soldering stability while enhancing PCB corrosion resistance.

High current carrying capacity and stable soldering performance are key advantages of rigid-flex PCBs.

Mature Manufacturing Capability Meets Complex Structural Requirements

Rigid-flex PCB manufacturing is challenging and demands tighter process control.
