Press Release from Taiyo Techno Rex: Announcement of Participation in the 40th Internepcon Japan

I would like to introduce the "Technical Information" related to FPC.

● 6-layer stacked via FPC Achieves further high-density wiring with a stacked via structure using via filling technology. Contributes to improved design flexibility by effectively utilizing wiring space. ● MSAP method Realizes high-precision and high-density fine wiring with enhanced plating. Excellent rectangularity of wiring cross-section allows for wiring formation as envisioned. ● Pattern via fill FPC Achieves high-density wiring and pad-on-via by combining MSAP and via filling methods. ● Fine pitch thick copper FPC Contributes to miniaturization of devices with large current and high-density wiring. ● High-frequency fluorine composite 3-layer FPC Combines noise countermeasures and miniaturization with fluorine composite material FPC that has excellent dielectric properties. Suitable for conversion from coaxial cables. ● High-frequency compatible FPC Proposes optimal design and materials based on analysis results. ● Transparent FPC An FPC with excellent light transmittance and heat resistance, capable of chip mounting. Allows for wiring routing without compromising product design.

Are you aiming for "zero missed leaks" in liquid filling processes? A new liquid leak inspection device utilizing flexible printed circuit boards (FPC)!

An FPC is installed at the mouth of "liquid-filled containers" flowing on production lines such as conveyor belts, enabling instant detection of minute liquid leaks. This contributes to the automation of line stoppages and the elimination of defective products. It is a new inspection solution that realizes "visualization" for quality improvement, cost reduction, and standardization of inspection processes. 【Features】 - High-precision surface detection that surpasses visual inspection capabilities - Inline installation on existing lines is possible (retrofit compatible) - Compatible with various shapes such as bottles, pouches, and nozzles - Eliminates reliance on specific personnel, enabling unmanned operation without the need for training - Automation and standardization of inspection processes through the supplementation of visual inspections - Addresses labor shortages with 24-hour unmanned inspections 【Benefits of Implementation】 - Increased efficiency and improved yield in pre-shipment inspections - Reduced risk of returns and recalls - Lower labor and training costs - Standardization of quality across overseas locations The FPC can be customized according to container shapes through in-house design and manufacturing.
