We will implement it in the substrate and in the hearts of our customers.
We perform circuit board assembly. Depending on the production quantity and number of components, we carefully assess which assembly method—machine assembly (mounting), hand soldering, or manual placement—would be most cost-effective, as well as the outlook for subsequent production, and provide you with a suitable circuit board assembly method and estimate. Additionally, we specialize in small-batch prototypes of various types of circuit boards and can accommodate hand soldering and manual placement for loose components. We can also offer proposals that keep initial costs down without using metal masks. 【Features】 - Support for single circuit boards, proposing appropriate assembly methods - Hand soldering technology for 0402 capacitors - Possession of assembly lines for both lead-free and eutectic solder - Procurement of assembly components, eliminating the hassle of sourcing *For more details, please download the PDF or feel free to contact us.
Skilled workers perform precise tasks quickly, one by one!
Our company performs substrate mounting using flow soldering and micro soldering. After accommodating automatic mounters (in collaboration with partner companies), we also support mass production for medium lots and above with back-mounted assembly. Please feel free to contact us if you have any requests. 【Sales Items】 ■ Flow Soldering - Insertion components are collectively soldered in a dip tank. - There are dedicated dip tanks for eutectic and lead-free soldering. ■ Micro Soldering - Back-mounted components or repairs are done using hand soldering. - We can solder irregularly shaped components that cannot be mounted with SMT machines using skilled techniques. - Hand soldering is possible for components ranging from 1005 chip parts to irregularly shaped parts, etc. *For more details, please download the PDF or feel free to contact us.

Solve difficulties in the early stages of circuit board design! We make it possible to realize unique circuit board designs from prototype to mass production.
We provide implementation services for substrates and components that are difficult to implement and operate using standard manufacturing equipment and methods. We accommodate 3D structures, large substrates, and materials that are difficult to heat. We can also work with new materials, not just existing ones. By using manual labor and original jigs for implementation, we respond to various requests. We can handle even small quantities, which is useful for experiments and prototype production. 【Service Examples】 - Design of sample substrates for functional evaluation that display characters in a dot matrix format using LEDs on glass-like substrates. - Production of temporary functional evaluation substrates in cases of defective substrate designs or errors in metallization and plating specifications. - Design and implementation of large ceramic substrates and 3D structure substrates. *For more details, please refer to the PDF materials or feel free to contact us.
By designing the circuit board from the perspective of the assembly site, customers can achieve benefits such as reduced labor costs and improved quality.
