Rigid-Flex PCB Manufacturer | High-Density Rigid-Flex Circuit Board Solutions
As a leading rigid-flex PCB manufacturer certified to IPC-6013D Class 3, we offer high-reliability rigid-flex PCB manufacturing services from prototyping to mass production. Utilizing a composite laminate structure of polyimide substrate (PI) and modified epoxy resin, we achieve dynamic bending performance exceeding 100,000 cycles (MIL-P-50884 standard), meeting the stringent 3D routing demands of military, medical, and automotive electronics.
Core Process Advantages:
✅ Laser Drilling Precision ≤50μm: Supports any-layer HDI interconnection and blind/buried via stacking designs, increasing routing density by 60%.
✅ Precise Etching Control: Achieves line width/spacing of 0.075mm, compatible with 0.35mm pitch BGA chip packaging.
✅ Coverlay Laser Cutting: Tolerance ±0.1mm, eliminating material stress cracking caused by traditional stamping.
✅ Rigid-Flex Transition Zone Reinforcement: Step-wise copper foil thinning to prevent bending fatigue fractures.
Key Application Scenarios:
- Implantable Medical Devices: Ultra-thin flexible zone thickness ≤0.15mm, certified to ISO 13485 for biocompatibility.
- Aerospace Electronics: Wide temperature range stability from -55℃ to 180℃, CTE matching ceramic chip carriers.
- Foldable Smartphones: Solutions with bending radius R＜1.5mm, achieving a mass production yield rate ≥98.5%.
2025 Technology Upgrades:
▸ Introduction of roll-to-roll (R2R) continuous production lines to shorten lead times to 72 hours.
▸ Development of nano-silver conductive adhesive to replace traditional plating, reducing Z-axis thermal expansion coefficient by 40%.
▸ Application of 3D optical inspection systems for real-time monitoring of flexible zone wrinkle defects (sensitivity 5μm).
