  1. Long Size PCB: Challenges & Solutions Manufacturing Excellence by SQPCB https://sqpcb.com/products/long-size-pcb-2/

  2. circuit board production • The electronics industry demands larger PCBs for advanced integrations. • Long size PCBs support continuous LED arrays, telecom modules, and industrial systems. • SQPCB specializes in manufacturing these boards with precision and reliability.

  3. What is a Long Size PCB? • Typical PCB length limit: ~610–678 mm. • SQPCB capability: single/double-sided up to 1.5 m; 4-layer up to 1.2 m. • “Long size” means larger than standard — enabling extended electronic applications.

  4. Standard Manufacturing Limitations • - Equipment optimized for standard sizes. • - Exposure machines risk misalignment for long boards. • - Drilling precision decreases over length. • - Handling and forming can cause deformation. • - Testing setups require customization.

  5. Core Challenges in Long PCB Fabrication • - Dimensional expansion/shrinkage during lamination. • - Misregistration between layers. • - Drilling offsets and warpage. • - Solder mask clearance issues. • - Lower yields without advanced process control.

  6. SQPCB’s Specialized Solutions • - Laser Direct Imaging (LDI) for high accuracy. • - Automated text printing for uniformity. • - In-house process control (lamination to finishing). • - Proven capability up to 1.5 m boards. • - Flexible prototype-to-mass production service.

  7. Key Application Industries • - LED Lighting (continuous arrays, strips) • - Telecommunications (antennas, base stations) • - Medical Equipment (imaging systems) • - Industrial Control (automation systems)

  8. Why Choose SQPCB? • - Specialized long board manufacturing. • - Advanced imaging and drilling technology. • - Full in-house quality control. • - Capability beyond standard limits. • - Reliable partner for extended board designs.

  9. Summary & Takeaways • - Long size PCBs pose unique manufacturing challenges. • - SQPCB’s technology ensures precision and yield. • - Ideal for industries requiring extended PCBs. • - Proven expertise in handling >1 m length designs.
