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.

"With high-precision dimming settings of 256/1000 gradations, you can achieve your desired results." The new 1-channel dedicated model LLBLM-A maximizes the performance of high-brightness LEDs. It offers high light stability through constant current control and flexibly accommodates a wide range of inspection and lighting applications with three types of interfaces: parallel, RS232C, and LAN. In addition to intuitive operation via the front panel, it supports high-precision dimming with 256/1000 gradations (256 gradations in parallel mode). The available emission colors are G (green) and B (blue). This new model balances stable light output with ease of use. For more details, please feel free to contact us.

Last month, we held a winter safety conference organized by our company. We have compiled the details and atmosphere of the day, as well as information on winter labor accidents, into a PDF. We would appreciate it if you could take a moment to read it.
