End face electrode substrate "End face through-hole substrate"

End face electrode substrate "End face through-hole substrate"

Cutting the through holes at the ends of the substrate with contour processing! Suitable for mounting holes and power supply units, etc.

The "end face through-hole substrate" is created by cutting the through-holes at the edges of the substrate through contour processing. In conventional end face through-holes, copper burrs were generated during cutting, but thanks to our unique process, we can provide end face through-holes without burrs even with router processing. Please feel free to contact us when you need our services. 【Applications】 ■ Mounting holes ■ Power supply units ■ Converter substrates ■ Module substrates, etc. *For more details, please refer to the PDF document or feel free to contact us.

End face electrode substrate "Partial etching through-hole substrate"

End face electrode substrate "Partial etching through-hole substrate"

Only the copper in the cut section of the through hole is removed by etching! The board thickness can be accommodated from 0.04 to 0.3 mm.

We would like to introduce our "Partial Etching Through-Hole Substrate." In printed circuit boards used as substrate for devices, after component mounting, through-holes may be diced and used as soldering electrodes. However, cutting the copper plating of the through-holes inevitably leads to burr formation. Our company enables the production of cut-through-hole substrates without burrs by selectively etching away only the copper at the cut portions of the through-holes. [Applications] ■ Substrate boards for devices with through-hole electrodes, etc. *For more details, please refer to the PDF document or feel free to contact us.

Resistor hole filling board

Resistor hole filling board

By embedding solder resist ink in the through-hole section, it is possible to cover it!

We would like to introduce our "Solder Mask Plugging Board." By embedding solder mask ink into the through-hole areas, it is possible to cover them. This prevents flux and solder from creeping up to the surface during assembly. Please feel free to contact us when you need assistance. 【Applications】 ■ Device boards, etc. *For more details, please refer to the PDF document or feel free to contact us.

Silicone printed circuit board

Silicone printed circuit board

Support for metal-based substrates is also possible! Suitable for applications such as heat resistance and UV equipment.

We would like to introduce our "Silicone Printed Circuit Board." Our silicone ink has high weather resistance against heat and the recently noted UV-C, as well as a high reflectivity. Although it is prone to bleeding, requiring a larger clearance with the circuit, we can provide silicone ink-coated boards with a minimum clearance of 0.2mm from the edges of the mounted circuit, thanks to our unique technology. [Applications] ■ Heat-resistant, UV equipment-related, etc. *For more details, please refer to the PDF document or feel free to contact us.

Achieving high-density implementation and high heat dissipation. New possibilities with copper inlay substrates.

Achieving high-density implementation and high heat dissipation. New possibilities with copper inlay substrates.

In the era of IoT, we propose the use of copper inlay substrates and metal-based substrates for heat dissipation solutions, as well as ultra-thin substrates to enhance design flexibility for product miniaturization and thinness.

We solve your heat-related issues with Sanwa Electronics Circuit's heat dissipation substrates. In IoT devices such as 5G, the heat generation of components is increasing, and due to higher density, fanless structures are required, necessitating effective heat dissipation in limited areas. LED lighting also generates more heat with increased brightness, making it essential to efficiently dissipate heat. Additionally, there is a demand for integration into limited spaces and for designs that accommodate specific shapes. 【Products Offered】 ■ Copper Inlay Substrates - By embedding copper coins into the substrate, efficient heat dissipation to the backside is possible. - Various diameters of copper coins are always in stock. ■ Metal Base Substrates - Single-sided boards made of aluminum or copper are available. - Our technology allows for double-sided boards to be affixed with heat dissipation sheets. ■ Bendable Aluminum Substrates - Thin aluminum base substrates with a thickness of 0.40mm can be shaped by bending. - The use of flexible resins and aluminum allows for the maintenance of bent shapes. ■ Thin Rigid Substrates - We can accommodate incredibly thin double-sided rigid substrates down to 0.04mm. *For more details, please feel free to contact us. Our sales representatives will provide you with an explanation right away.

[Thin Plate Bending Circuit Board] A substrate with a thickness of 0.1mm or less can be used by bending!

[Thin Plate Bending Circuit Board] A substrate with a thickness of 0.1mm or less can be used by bending!

Using FR-4 material with a thickness of 0.1mm or less, it can be bent and used like a flexible circuit board. Initial costs can be addressed at a low price.

Our "Thin Plate Bending Circuit Board" uses glass epoxy substrates (FR-4) with a thickness of 0.1mm or less, making it suitable for applications that require several bending actions during bending and assembly. Thanks to router processing, there is no need for coverlay processing molds or outline processing molds. This helps reduce initial costs from prototyping to mass production, allowing for cost-effective manufacturing of products. It is suitable for circuit boards that require component mounting and bending, and can be used in industrial equipment, LED lighting, and wearable devices (such as VR headsets and controllers). 【Features】 - Ideal for applications that require several bending actions during bending and assembly. - More cost-effective in terms of product and initial costs compared to flexible circuit boards (when compared to our offerings). - No need for coverlay processing molds or outline processing molds. - Capable of handling small to medium production volumes. *For more details, please refer to the materials. Feel free to contact us with any inquiries. *Materials for special circuit boards other than thin plate bending circuit boards can also be viewed via download.
