Introducing Our 4-Layer Flex-Rigid PCB for Control Modules
We are pleased to present our cutting-edge 4-layer flex-rigid PCB, expertly crafted to merge the best features of rigid PCBs and flexible FPCs. This innovative product is specifically designed for applications requiring high-density wiring, resistance to vibration and bending, and efficient use of compact spaces.
Key Features and Benefits
Composite Structure: Features a Tg170ºC FR-4 rigid substrate combined with a 0.16mm polyimide flexible substrate for enhanced performance.
Surface Treatment: Equipped with electroless nickel immersion gold (ENIG) for superior reliability and excellent electrical characteristics.
Thickness:Rigid PCB part: 1.50mm (finished thickness)
Flexible FPC part: 0.16mm
Copper Thickness: Utilizes 1oz (35μm) copper per layer for high current-carrying capacity.
Aesthetic and Functional Design
Solder Mask: Green solder mask enhances both functionality and visual appeal.
Silkscreen Marking: Clear white markings for easy identification.
FPC Coverlay: Yellow protective film for bend resistance and anti-oxidation.
Dimensions: Single piece size is 125.60mm × 45.60mm, with a panel design of 191.20mm × 116.60mm accommodating 3 pcs per set.
Advanced Manufacturing Techniques
Micro-Via Design: 0.2mm via diameter suitable for high-density wiring, featuring a via filling and electroplating process for a smooth surface.
Quality Assurance: 100% electrical testing (ET testing) ensures optimal conductivity and insulation, adhering to IPC-A-600 Class 2 standards.
