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.

We sincerely look forward to your visit during this event. Please note that pre-registration (free of charge) is required to attend the exhibition, so we kindly ask you to register using the link below. https://www.logistech-online.com/jp/registration.php?exhibitor=EX000072 If you would like an invitation, please request it through our contact form.

Contec has added a BTO menu for the Windows 11-based embedded OS - Windows 11 IoT Enterprise LTSC 2024 to its industrial computer "MR4310 series" and has started accepting orders.

Contec has developed the Ethernet wireless converters "RP-WAH-SR12" and "RP-WAH-SR22," which utilize 920MHz sub-gigahertz wireless (IEEE 802.11ah) to enable Ethernet communication wirelessly even at distances of up to 1 km. Sales began on August 21, 2025. The new products are compact IEEE 802.11ah compliant wireless LAN converters that can be installed in various locations. The new Wi-Fi standard "IEEE 802.11ah," which utilizes sub-gigahertz wireless communication, became available in Japan in September 2022. It operates in the 920MHz band without the need for a license and can be used outdoors. Compared to conventional 920MHz wireless communication, it enables high-speed communication and the establishment of long-distance networks, making it expected to be utilized in large factories, plants, and farms. The new Ethernet wireless converters are designed to be lightweight and compact, allowing for installation in various locations such as walls and DIN rails with the included mounting brackets. Additionally, they support external antennas, enabling the construction of flexible wireless LAN systems.

Contec has developed a super compact business computer equipped with the Intel(R) Core(TM) Ultra processor (Series 1), and has started accepting orders for the business computer "LPC-500 Series" (hereinafter referred to as the new product) from August 28, 2025. The new product is a super compact business computer featuring the Intel(R) Core(TM) Ultra 5 processor 125U (Series 1, Meteor Lake-U). It is equipped with "Intel(R) AI Boost," which integrates an NPU into the CPU, allowing for the execution of AI functions such as image recognition and voice processing at high speed and low power consumption while reducing the load on the CPU and GPU. With ultra-compact dimensions of 150(W) × 150(D) × 33(H) mm, it comes with a vertical stand and VESA mounting brackets, enabling installation in tight spaces on desks, behind displays, or inside equipment without restriction. It adopts a BTO (Build to Order) method that allows customers to freely choose memory capacity, storage, OS, and more, enabling the order of a PC with specifications optimal for their needs and budget starting from just one unit.

Thank you very much for your continued support. We would like to inform you that our company will suspend product shipping operations for inventory purposes due to the interim financial closing on the following dates. We apologize for any inconvenience this may cause and appreciate your understanding. Shipping suspension period: Tuesday, September 30, 2025.
