Case Studies of Our Polyimide Flex PCB Project
Project Background
A deep space exploration device requires long-term operation under conditions of intense vibration, wide temperature range (-55°C to 125°C), and strong radiation. The original solution used traditional rigid wiring harnesses, weighing 1.5 pounds (approximately 680 g), with complex wiring and error-prone assembly, failing to meet the device’s dual requirements for lightweight design and reliability.
Solution
1. Material Selection
- The substrate employs glass fiber reinforced polyimide (copper-clad glass-supported polyimide) and pure polyimide film (flexible polyimide film), combined with polyimide prepreg and acrylic adhesive, ensuring dimensional stability and chemical resistance at high temperatures.
- The cover layer is entirely polyimide, covering copper foil and the pad-trace transition area, significantly enhancing bending resistance.
2. Structural Design
- Designed as a 30-layer rigid-flex combination board with 7 press cycles, achieving high-density interconnection and isolating signal, power, and ground layers within limited space.
- Teardrop-shaped pad-trace transition structures reduce stress concentration, preventing copper foil fracture caused by dynamic bending.
3. Process Innovation
- Concurrent engineering was adopted, and the entire manufacturing process was completed in-house, shortening the development cycle and reducing outsourcing risks.
- The polyimide cover thickness in critical areas was increased to 25 μm, further improving mechanical durability.
Solution Results
- Significant Weight Reduction: The final circuit board weighs only 87 g, approximately 87% lighter than the original wiring harness, greatly reducing system load.
- Enhanced Reliability: Operated continuously for 90 days in extreme Martian surface environments, far exceeding the original 30-day mission target, with no electrical or mechanical failures.
- Technology Inheritance: This solution became the baseline design for subsequent deep space missions, validating the maturity and reliability of polyimide flexible circuits in aerospace-grade applications.
