Heat-dissipating substrate "DPGA"

Heat-dissipating substrate "DPGA"

This is a substrate with unique high heat dissipation properties developed by Daiwa Kogyo Co., Ltd.

"DPGA" stands for "Daiwa Process Global Advance," which is a process developed independently by Daiwa Industrial that uses metal Cu bumps for interlayer wiring connections. A substrate with high heat dissipation characteristics enables high brightness and long lifespan of LEDs, as well as miniaturization of heat sinks. 【Features】 ○ Interlayer connection using metal pillars (copper bumps) → Achieves low resistance, high connection reliability, and high thermal conductivity ○ Copper bumps can be of any shape and size → For cylindrical shapes, diameters can range from 0.3 to 4.00 mm ○ Mixing of copper bumps of different sizes is possible ○ Improved thinness, lightness, and rigidity → Minimum board thickness: 0.3 mm, using prepreg for the insulation layer ○ Maximizes the functionality of LEDs → Ideal for LED substrates (liquid crystal panels, lighting) and automotive substrates For more details, please contact us or download the catalog.

High Heat Dissipation Substrate 'DPGA-M'

High Heat Dissipation Substrate 'DPGA-M'

DPGA is made double-sided and supports back-side wiring! Equal-length wiring is possible even when parallel circuits are present.

"DPGA-M" is a high thermal conductivity substrate that features a single-sided multilayer design and supports backside wiring. By adopting a single-sided multilayer structure, it significantly enhances design flexibility, allowing for backside wiring. Although it has multiple layers stacked on one side, it is possible to penetrate copper bumps. This enables direct connection of high thermal conductivity components to the copper base and heat sink. 【Features】 ■ Single-sided multilayer structure ■ Enables backside wiring ■ Allows for equal-length wiring even in the presence of parallel circuits ■ Significantly increases design flexibility ■ Enables direct connection of high thermal conductivity components to the copper base and heat sink *For more details, please refer to the PDF document or feel free to contact us.

High Heat Dissipation Substrate 'DPGA-S'

High Heat Dissipation Substrate 'DPGA-S'

Separating the copper base on the back and ensuring insulation! Maintaining the strength of the substrate even after separating the copper base.

The "DPGA-S" is a high thermal conductivity substrate that separates the copper base on the back side and is designed for insulation. Thanks to the high thermal conductivity provided by the through-type copper bumps, it is possible to make the insulation layer up to 0.3mm thick. This allows for maintaining the strength of the substrate even after separating the copper base. Additionally, by separating the layers, it is also possible to mount electrodes on the copper base side. 【Features】 ■ High thermal conductivity due to through-type copper bumps ■ Insulation layer can be made up to 0.3mm thick ■ Allows for mounting electrodes on the copper base side by separating the layers ■ The back side can also be utilized for electrical connections *For more details, please refer to the PDF document or feel free to contact us.

Copper Pin Embedded Substrate "DPGA-EF"

Copper Pin Embedded Substrate "DPGA-EF"

Embed copper pins directly under the heating components! This can reduce the cost difference based on the number of copper pins.

"DPGA-EF" is a type of substrate that embeds copper pins only in the necessary areas. It can be produced at a lower cost compared to copper bases with bumps. The copper pins are inserted into the holes of the rigid substrate and fixed with resin. Unlike press-fitting, there is no risk of cracks or other issues. Additionally, the copper pins are embedded all at once. Unlike the press-fitting method, the cost difference based on the number of copper pins can be minimized. 【Features】 ■ Both sides of components can be mounted ■ Heat-generating components can be cooled precisely ■ There are no concerns about cracks or chemical residue, as it differs from the copper pin press-fitting method ■ It can be produced at a lower cost compared to copper bases with bumps ■ Unlike the press-fitting method, the cost difference based on the number of copper pins can be minimized *For more details, please refer to the PDF document or feel free to contact us.
