The production system aims to introduce equipment and improve efficiency to accommodate short delivery times, a wide variety of products, and small lot production!
Our company provides printed resistive substrates in various fields such as automotive, motors, and cameras. Among them, the "heat-resistant substrate with a fine pitch pattern width of 30μ to 90μ" has been adopted as an important substrate related to automotive safety and has received positive evaluations. We are also focusing on the development of human resources backed by experience rather than relying solely on machines. We are preparing to meet the diverse needs of everyone. 【Examples of manufactured products】 ■ Slide volume using printed resistors ■ Transfer substrate using printed resistors ■ Actuator substrate using printed resistors ■ Heat-resistant substrate with a fine pitch pattern width of 30μ to 90μ ■ Carbon paste manufactured and sold in-house *Please feel free to contact us for more details.
Waterproofing, long-life enhancement, and earthquake resistance of the implementation board are recommended with resin potting!
Resin potting involves injecting urethane resin into cases, effectively shutting out dust, dirt, and water. Additionally, since the circuit board is fixed in place, it can be protected from vibrations. It is recommended for waterproofing, extending the lifespan, and enhancing earthquake resistance of mounted circuit boards. We will carry out the work according to your requirements, so please feel free to contact us. 【Benefits of Resin Potting】 ■ No worry about dust or dirt adhering to the circuit board ■ Excellent waterproofing and moisture resistance ■ Strong against vibrations and shocks as the case can be filled and fixed with resin ■ Can extend the component replacement cycle, making it effective for products intended for overseas markets ■ Prototyping is possible *For more details, please refer to the PDF materials or feel free to contact us.

Although the hardness is high at 76, it does not put stress on the substrate! Introduction of resin potting examples.
If waterproofing is necessary, if you want to protect the circuit board from vibrations, or if you are concerned about the reduced lifespan of the mounted circuit board due to dirt, resin potting is the solution. Black potting has a high hardness of 76, but it has the advantage of not putting stress on the circuit board. There are no limits to the work size for resin potting. Please feel free to consult us regardless of the size of the circuit board. 【Advantages of Black Potting】 ■ High hardness of 76, but does not stress the circuit board ■ Excellent waterproofing (equivalent to IP67), dustproofing, explosion-proofing, and earthquake resistance ■ Prototyping is possible *For more details, please refer to the PDF materials or feel free to contact us.

Introducing a black potting material with IP67 equivalent waterproof performance and a hardness of 76A, ideal for vibration protection and unobtrusive when mounted in vehicles!
For vibration resistance and waterproofing measures for automotive substrates, black potting is recommended. The reason black potting is recommended for automotive substrates is that it has waterproof performance equivalent to IP67, making it completely suitable for humid environments. Additionally, with a hardness of 76A, it also addresses one of the main concerns for automotive substrates, which is vibration resistance. We often receive various requests for applications beyond automotive substrates, so please feel free to consult us if you have any inquiries. 【Features】 ■ Excellent waterproof performance ■ Suitable for vibration resistance ■ Black potting material that does not stand out when installed in vehicles ■ Recommended for products to be exported overseas where you do not want the mounted circuits or patterns to be visible *For more details, please refer to the PDF document or feel free to contact us.
