Ultra-fine lines, high density, and high-definition flexible printed circuit boards have made it possible to form ultra-fine circuits through the fusion of MSAP technology and via filling techniques!
The miniaturization and high functionality of electronic devices are advancing, and along with this, there is a demand for finer circuit formation. One method for forming wiring by etching copper foil (subtractive method) and a high-resolution circuit formation method is to form wiring by plating on ultra-thin copper foil (semi-additive method). The method we are introducing this time is one of the semi-additive methods, called "MSAP (Modified Semi Additive Process)." By using the MSAP method, it has become possible to achieve ultra-fine lines and high-density pattern formation, which is difficult with the subtractive method. Additionally, by combining it with the "via filling technology," which fills through-hole holes with copper plating, it becomes possible to create wiring on the through-holes, further increasing wiring density. **Features of the MSAP Method:** - Circuit formation through plating deposition enables high-precision fine wiring. - Excellent rectangularity of wiring cross-section contributes to reduced transmission loss. - Superior for high-frequency substrates/IC mounting. By merging these two processing technologies, we have realized "ultra-fine high-density FPC." #FlexibleSubstrate #Substrate #HighResolutionSubstrate #Flex #FlexiblePrintedCircuitBoard

Company information
Taiyo TechnoRex Co., Ltd. continues to operate in the fields of prototype development of flexible printed circuit boards (FPC) and printed circuit board testing systems. Since FPC is fundamentally related to the structure of hardware, both high precision quality and shortened development time are required. We have extensive experience and know-how in the manufacturing processes of single-sided FPC, double-sided FPC, multilayer FPC, and their advanced variants, and we continuously improve and enhance our technology, resulting in consistent evaluations of our delivery times and quality. Additionally, while we are advancing further miniaturization and high density technically, we are also undertaking new initiatives such as bump-type and electroplating with special materials. On the other hand, our printed circuit board testing systems mainly consist of electrical inspection systems and final appearance inspection systems, which are adopted in mass production sites for FPC and package/module-type substrates. They operate day and night in quality control settings for substrates used in smartphones, automotive applications, and various electronic devices. We will continue to respond to the increasingly diverse market needs in the future. *On December 21, 2023, the company name was changed from "Taiyo Kogyo Co., Ltd." to "Taiyo TechnoRex Co., Ltd."*
