We would like to introduce a case where we conducted the artwork and manufacturing of a high-voltage circuit board. We received an inquiry from a customer developing a high-voltage circuit board for the first time, and we proposed the circuit board design values primarily from our side. In this case, there were no clearly defined standards to comply with, so we made proposals to satisfy functionality, performance, and safety, and after adjustments with the customer, we finalized the specifications. 【Outline Specifications】 ■ Output: Maximum AC/DC 5kV ■ Insulation Design: Between other blocks = AC2kV Between Low Voltage block and High Voltage block = AC4kV (to the extent possible) *For more details, please refer to the related links or feel free to contact us.

We would like to introduce a case where we received a request for high-speed transmission artwork (10Gbps × 8 lanes) to lens assembly. Considering the performance (characteristics of each signal), the capabilities of the wire bonder, and the shape of the lens, we determined the die pad shape, the position of the second bonding, and the pattern layout. We accurately aligned the center of the lens above the center of the two optoelectronic device emission areas that were precisely die-mounted, using image recognition to position the center of the microlens array one point at a time. [Case Overview] ■ Challenge - The center of the emission point of the bare chip must be aligned with the center of the lens with an accuracy of a few micrometers, but there is no budget for the production of special alignment jigs. ■ Result - The center of the emission area of the optoelectronic device directly below was aligned with the center of the lens directly above, achieving implementation without creating special jigs. *For more details, please refer to the related links or feel free to contact us.

With the energy-saving of devices and the low voltage of ICs, the use of DC/DC converters with excellent conversion efficiency is increasing. In recent years, DC/DC converters have become very frequently used due to improvements in several drawbacks, including high performance, high functionality, miniaturization, and reduction of external components. However, to effectively utilize them, it is important to minimize noise generation and reduce the impact of generated noise on other circuits. Therefore, assuming that the selection of peripheral components considering noise has been adequately done, we will verify "how much noise countermeasures can be achieved through substrate patterning" with practical examples. *For detailed content of the article, please refer to the related links.

A major feature of our artwork design is that it is created by experienced hardware developers from major set manufacturers who are well-versed in both circuits and artwork, resulting in high-level artwork design. We handle a wide variety of circuit boards, allowing for extensive support in board development and design. In addition to beautiful layouts, we prioritize understanding the actual logic and aim to create artwork designs that reflect the developer's intentions and desired characteristics. 【Design Technology】 ■ Noise countermeasures in DC/DC converter boards ■ Thermal countermeasures (motor driver) pattern design ■ Board design that brings analog concepts into the digital realm ■ Achieving the desired functions and performance at a high level with extensive circuit knowledge and layout know-how *For more details, please refer to the related links or feel free to contact us.

An important factor in machine design, circuit design, and substrate design is "controlling heat." The heat dissipation path, from the perspective of thermal resistance, is significantly large, as heat conducted from components to the substrate wiring is transmitted into the air. With the recent trend of high-density integration of components and miniaturization of devices, the importance of measures through substrate patterning has been increasing. Here, we will introduce specific thermal countermeasures based on verification experiments regarding "how much difference substrate patterning can make in thermally demanding circuits." *For detailed content of the article, please refer to the related links.
