Types and Examples of High-Performance FPC [Special Bumps, Long and Ultra-Fine, High Flexibility]

Our company has further improved the technology for forming high-density wiring in our core business of electronic substrates, specifically in flexible printed circuit boards (FPCs). In recent years, electronic devices such as medical equipment and industrial machinery have been advancing in miniaturization and lightweight design. To incorporate many functions into limited space, there is a demand for increased wiring density on the substrate. Therefore, we have been working on establishing filled via technology and improving the M-SAP method. The filled via structure involves filling vias (holes) made by laser in the insulating layer with copper plating, ensuring electrical connections on both sides of the substrate while reducing the recesses of the vias, which allows for component mounting on the vias and leads to high-density mounting. On the other hand, the M-SAP method significantly improves line width management by laminating copper to form circuits, enabling high-density wiring. This time, based on the pattern via fill method that leverages these characteristics, we successfully formed wiring with a pitch of 30μm on a double-sided substrate with a filled via structure. We will continue to aim for further improvements in high-density wiring formation technology through ongoing development, prototyping, and verification.

◎FPC (Flexible Printed Circuit Board): Under the theme of "Discovering Applications for FPC," you can experience the characteristics of FPC in four zones: lightweight, flexible, fine, and special. 1. Comparison of weight between rigid boards and FPC 2. FPC that you can actually touch and bend 3. Reduction of board area due to high-density wiring 4. FPC with special features such as transparent, high-frequency, and pressure-resistant types Additionally, we are also showcasing next-generation circuit technologies such as stack vias and via fills. It's not just about FPC! We have live demonstrations of 'FA Automation' and the latest appearance inspection system using AI technology! ◎FA Automation: By achieving teaching-less automation through visual feedback control, we eliminate the burden of calibration and realize high-precision, high-speed operation. We have prepared a demonstration for the transport of rigid boards. ◎The latest final appearance inspection system, the AI system 'TY-VISION XAIS,' is now in Chapter 2! In addition to improving efficiency by reducing false positives in the final appearance inspection process, it also supports defect detection using AI. It is effective for defects with minimal brightness differences that are difficult to detect with inspection devices, even though they can be identified visually.
