As electronic products continue to evolve towards thinner profiles and higher performance, ultra-long Flex PCBs have become a critical solution for advanced connectivity needs. Flex Plus has been dedicated to the design and manufacturing of flexible printed circuit boards for many years. Through extensive production experience and rigorous quality control, we meet the diverse demands of super-long Flexible circuit boards, providing reliable support for various applications.
Super long flex PCB manufacturing capabilities
Flex Plus FPC has overcome numerous technical challenges in the production of ultra-long Flex PCBs, showcasing its outstanding technical expertise:
High-Precision Alignment Technology
The production of ultra-long flexible circuit boards requires extremely high precision, especially in complex circuit wiring. Flex Plus FPC can achieve high-precision alignment even when the length of the circuit board increases, meeting the needs of complex circuit design.
Large-Scale Copper Lamination
Ultra-long Flex PCB boards require handling oversized copper materials. Flex Plus has optimized the material handling process to ensure uniform copper distribution over large areas, maintaining excellent conductivity and stability, making the product suitable for high-frequency applications.
High-Reliability Bend Testing
To guarantee durability in real-world applications, Flex Plus rigorously conducts bend and fatigue tests during production. This ensures the flexibility and long service life of its products, making them ideal for industrial automation, and medical devices applications.
The application of these advanced systems not only ensures the superior electrical performance of Flex PCBs but also significantly enhances quality control efficiency on the production line.
Professional production equipment for super long Flex PCB
Flex Plus understands the elevated requirements for equipment when manufacturing super-long Flex PCBs and has introduced and customized the following advanced systems:
Ultra-Long Lamination Presses
Supports large-format flex PCB lamination, ensuring uniform and stable interlayer bonding.
1. Laminating machine table size: 550×2600mm
2. The equipment heats up quickly, with even tabletop heating and the pressure is uniform.
Wide-Format Exposure Systems
Designed for precise imaging of ultra-long circuit patterns, ensuring consistent and clear circuitry.
1. Effective size of the exposure tabletop: 2.5×3.5 meters
2. Utilizing LED lights as a parallel exposure light source, with the exposure energy uniformity of ≥80%.
Smart Inspection Systems
Featuring automated optical inspection (AOI) and flexible scanners, these systems guarantee that every part of an ultra-long PCB meets quality standards.
Specialized Hanger Device for Immersion Plating
Using dedicated fixtures for the gold plating production of long boards effectively prevents surface wrinkles and abnormal gold color issues. This ensures even exchange of the product in the plating bath, with uniform control of gold-nickel thickness across all areas of the product
Immersion plating is a key process for achieving high-quality surface finishes in super-long Flexible circuits. Flex Plus has developed and utilizes customized hanger devices specifically designed for super-long printed circuit boards, delivering the following benefits:
Uniform Plating Distribution: The hanger design minimizes deformation or movement of the long boards, ensuring an even coating across the entire PCB surface.
Efficient Current Distribution Control: Optimized electrode placement guarantees consistent plating thickness, meeting high-precision circuit requirements.
Reduced Defects and Contamination: Special materials and designs in the hanger minimize plating defects, such as bubbles or contamination, ensuring flawless surface finishes.
Specialized Electrical Testing Equipment
To ensure the electrical performance of super-long Flex PCBs meets design requirements, Flex Plus FPC has implemented high-precision testing systems tailored for large-format PCBs.
1. It has 4,096 test pins and can test over 2 meter long products at one time.
2. The test speed is fast can reflect the quantity and position of NG Flex PCB.
3. For extra-long products, we develop extra-long test racks to improve production efficiency.
