Completely solving the challenges of implementation boards in harsh environments! *A Q&A collection is currently being offered.

We also have detailed materials explaining mold (potting) and coating that can implement measures for waterproofing, humidity resistance, and earthquake resistance of the implementation substrate.

If the printed circuit board is used as is, it often leads to malfunctioning of the board, damage to components or the board itself, and a reduction in the lifespan of the board. Therefore, for printed circuit boards in harsh environments, measures such as waterproofing, moisture-proofing, vibration-proofing, dust-proofing, and explosion-proofing become necessary. As a countermeasure, resin molding (resin potting) can be used to inject urethane resin into cases, which can shut out dust, dirt, water, and vibrations. Additionally, since the board is fixed in place, it can be protected from vibrations. *Consideration for implementation is possible even without a case. Furthermore, by coating the surface of the board, it is possible to protect the board from dust, dirt, and moisture. *For more details, please refer to the PDF document or feel free to contact us.

Resin potting refers to waterproofing and dustproofing measures for mounted circuit boards!

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.

[Example] Black Potting - For waterproofing and dustproofing of mounted circuit boards!

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.

Vibration resistance and waterproof measures for vehicle-mounted circuit boards: black potting.

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.
