We can accommodate a wide range from small-sized substrates to large substrates with a size of "850mm x 500mm"! We also support 3D POP mounting!

We can accommodate a wide range of needs, from small-sized circuit boards to large circuit board assemblies measuring "850mm x 500mm"! We also support 3D POP assembly and have received various requests from semiconductor equipment manufacturers, including for prototype and mass production products. We offer a consistent manufacturing process from circuit board assembly to product assembly, providing a "one-stop service." Recently, the long lead times for electronic components have become a problem. We have received numerous requests to implement and assemble components in a timely manner as soon as they are obtained, in order to quickly ship products. At our company, we separate the lines for prototype production and mass production, and by implementing our unique production management, we enable parallel production of both prototypes and mass production, allowing us to flexibly respond to our customers' urgent needs. ■ Examples of requests: 【1】I want to finish assembly in a short lead time. 【2】I want to carry out both assembly and product assembly consistently. 【3】I have all the components, but I want to produce separately because I can't align with this month's production. 【4】I want to conduct incoming inspections for overseas products and components. *For more details, please feel free to contact us. https://yoho-denshi.com/index.html

A portable sterilization and deodorization device that can be carried in a bag. With USB connection, you can easily take care of the air anywhere! "I can always be clean."

This is a personal sterilization and deodorization device that can be easily used anywhere with a computer, mobile battery, or USB adapter, thanks to its USB connection. It is compact and lightweight, weighing only 230g. 【Mechanism for Clean Air】 By irradiating a high-density photocatalytic filter, which is our unique technology, with UV LED light, active oxygen (OH radicals) is generated on the surface of the filter, creating oxidative power. This sterilization and deodorization device quickly removes bacteria and odor-causing germs present in the air passing through the activated filter in just 1/300 of a second. It removes micro-droplets and germs, keeping the air clean at all times. Conventional HEPA filter air purifiers carry the risk of harmful substances dispersing during filter maintenance, but KOROSUKE's photocatalytic filter has self-regenerative capabilities and is maintenance-free, eliminating the risk of harmful substance dispersion. Unlike ozone air purifiers or hypochlorous acid air purifiers, it does not release ozone or chlorine, making it highly safe and allowing you to care for the air with peace of mind. ● For more details, please contact us or download the catalog.

<Title> Development of Gene Expression Control Technology through RNA Hacking In the latest presentation paper, we have utilized Abby. Associate Professor Yosuke Katsuta from Kumamoto University Graduate School of Advanced Science and Technology, Analytical Chemistry Laboratory (also co-founder of StapleBio), will be giving a presentation in an online seminar. He is working on the development of RNA hacking technology aimed at controlling gene expression by utilizing short nucleic acids named Staple to change the higher-order structure of target mRNA. He will present the latest data focusing on the results of cell experiments and animal experiments in the development of this technology.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.
