Export Rigid-Flex PCB for National Defense Communication Equipment

Special-Shaped Frame Surrounded Flexible Strip Structure

L-shaped long bendable flexible strips surround the central rigid board on all sides. It fits frame-shaped internal wiring of equipment and conforms perfectly to the housing contour, eliminating external connecting cables.

Long Travel & High Bending Endurance

Rolled copper PI flexible strips achieve ≥120,000 dynamic bending cycles without open circuits. The minimum bending radius is ≥1.5 times the thickness of the flexible strip. It resists vibration and avoids copper cracking under high-low temperature cycling.

Panelized Array Design for Mass Production

Multiple units arranged on one panel enable simultaneous SMT mounting for many pieces, greatly cutting manufacturing and assembly costs. Individual units can be separated via V-Cut or scoring after delivery.

Integrated Lamination Free of Delamination

Rigid boards and PI flexible strips are bonded at molecular level under high temperature and high pressure. No voids or delamination occur in transition zones, delivering far higher reliability than separate rigid board + FPC assembly solutions.

High-Density Connector Pads

Standard gold finger connector pads are reserved on the board for direct plug-in connection to the main controller. This simplifies assembly and minimizes faults caused by manual wiring.

Lightweight & Miniaturized

Replaces multiple discrete rigid PCBs and numerous cables. Internal wiring space inside the device is reduced by 50%, lowering overall equipment weight.

Blue Solder Mask for Visual Identification

Blue solder mask applied on rigid sections offers clear distinguishability, meeting standardized appearance requirements for industrial equipment and testing instruments.

Rigid-Flex Structure with Differentiated Thickness Zones

The 0.15 mm ultra-thin flexible zone enables multi-angle routing in confined spaces; the 2.0 mm thick rigid zone guarantees anti-shock mounting and large-area heat dissipation. It balances routing flexibility and structural rigidity for complex assembly of portable military equipment.

Thick Electroplated Hard Gold for Frequent Mating Scenarios

Dense and hard gold plating on contact surfaces provides wear resistance against repeated insertion/extraction, anti-tarnish and anti-salt-spray performance. Contact resistance remains stable during long-term field operation to prevent communication signal attenuation, satisfying high-reliability standards for defense equipment.

Military-Grade Weather Resistance for Export Applications

High Tg substrates matched with dedicated PP bonding system withstand harsh operating conditions such as intense sunlight in Pakistan and coastal salt spray. No delamination failure occurs during ocean shipping and storage, with complete and compliant customs documentation.

High-Precision Dense Circuit Layout

Fine line width & spacing supports multi-channel signal routing for communication. Controlled impedance reduces RF crosstalk and improves transmission stability for private network communication.

High Consistency in Panelized Mass Production

Matrix panel layout adapts to overseas automated SMT lines with low stress during depaneling. Stable production yield supports large-volume project delivery.

Full-Process Defense-Grade Quality Control

Full traceability from raw materials to finished goods. Comprehensive reliability tests including bending, thermal shock and salt spray comply with procurement audit standards for overseas defense communication customers.
