Thick copper busbar substrate and coil substrate [Proven up to a copper thickness of 3.0mm]

Thick copper busbar substrate and coil substrate [Proven up to a copper thickness of 3.0mm]

By substrate-izing busbars and coils used for high current applications, high insulation properties and a reduction in labor hours are achieved!

We have substrate-mounted busbars and coils used for high current applications in the heavy electrical and automotive industries. By substrate mounting, the following effects can be expected: - Substrate mounting of power devices such as IGBTs and SiCs - Installation on equipment after substrate mounting → Reduction of assembly work and prevention of miswiring - Space-saving due to substrate mounting and simplification of wiring → Miniaturization of the entire device - Generally, a thick copper substrate refers to a substrate with a copper foil thickness of 200μ (0.2mm) or more, but we have also achieved substrate mounting with 3000μ (3mm) copper plates. - The greatest advantage of substrate mounting is its high insulation performance and usability. The insulation layer using prepreg has a consistent thickness, so there is no concern about variation in thickness like with powder coating. - By covering areas other than the necessary parts with the substrate, handling becomes easier, and work during transportation and installation can be performed safely. *For more details, please refer to the PDF document or feel free to contact us.

[Concerns about Device Assembly] It requires technology to mount the circuit board onto the aluminum casing.

Achieving grounding of the aluminum section! This improves the usability and design flexibility of the aluminum section. By pre-installing and securing with screws, labor reduction becomes possible!

When it comes to aluminum base substrates, the mainstream products are those that have an insulating layer pre-attached to aluminum, released by substrate material manufacturers. However, this limits the choice of aluminum thickness and the dielectric constant of the substrate to only what is available in the existing lineup, imposing restrictions on design. Therefore, our company has made it possible to create aluminum base substrates using a unique method that bonds the substrate material to aluminum, allowing for customization according to your specifications. This significantly enhances design flexibility, enabling requests such as increasing aluminum thickness or using high-dielectric materials like Teflon or PPE for miniaturization. Additionally, it is possible to process the substrate after bonding, allowing for the creation of cavities for mounting components by machining only the substrate portion. 【Features (Aluminum Base Through-Hole Substrate)】 ■ Method of bonding substrate material and aluminum - High-frequency bonding film - Eutectic solder (lead-free options available upon consultation) ■ Realization of GND connection for the aluminum part ■ Dramatic improvement in the usability of the aluminum part ■ Automatic mounting via reflow is also possible (in cooperation with partner companies) *For more details, please refer to the PDF document or feel free to contact us.

Aluminum base substrate [Noise and heat countermeasures with aluminum grounding]

Aluminum base substrate [Noise and heat countermeasures with aluminum grounding]

Achieving grounding of the aluminum section! This improves the usability and design flexibility of the aluminum section.

When it comes to aluminum base substrates, the mainstream options are those that have an insulating layer pre-attached to aluminum, released by substrate material manufacturers. However, this limits the choice of aluminum thickness and the dielectric constant of the substrate to only what is available in the existing lineup, imposing restrictions on design. To address this, our company has developed a unique method of bonding the substrate to aluminum, allowing us to create aluminum base substrates using the desired substrate and aluminum. This significantly enhances design flexibility, enabling requests such as increasing aluminum thickness or using high-dielectric materials like Teflon or PPE for miniaturization. Additionally, post-bonding processing is possible, allowing for the creation of cavities for mounting components by machining only the substrate portion. 【Features (Aluminum Base Through-Hole Substrate)】 ■ Method of bonding substrate material to aluminum - High-frequency bonding film - Eutectic solder (lead-free options available upon consultation) ■ Achieves grounding of the aluminum section ■ Dramatically improves the usability of the aluminum section ■ Automatic mounting via reflow is also possible (in collaboration with partner companies) *For more details, please refer to the PDF document or feel free to contact us.

Hybrid substrate (honeycomb material laminated substrate)

Hybrid substrate (honeycomb material laminated substrate)

By combining different substrate materials in horizontal and vertical directions, we can reduce assembly man-hours and save space!

Hybrid substrates integrate multiple substrate materials with different characteristics by combining them in horizontal and vertical directions (layering), allowing for the unification of what was previously divided into multiple boards, thus achieving a reduction in assembly labor and space-saving. Additionally, we offer "honeycomb substrates" that are ultra-lightweight and have excellent electrical properties through a composite technology that incorporates honeycomb materials into the substrate and layers them. Honeycomb materials are particularly effective when bonded with fluoropolymer (Teflon) substrates. Fluoropolymers are used as materials for high-frequency substrates due to their low dielectric constant, but the base material itself is soft, making it difficult to handle. When scaled up, thin substrates can bend or break, while making the substrate thicker can lead to warping due to its own weight. Honeycomb materials are lightweight and have high strength, allowing for reinforcement of the substrate when bonded, which helps to reduce warping. Furthermore, not only does it contribute to weight reduction, but the air within the honeycomb also serves as an insulating layer, making it effective when a lower dielectric constant is desired. Moreover, because the honeycomb material provides reinforcement, handling becomes easier compared to when using the substrate alone, thus improving work efficiency. *For more details, please refer to the PDF document or feel free to contact us.*
