• Circuit board design and manufacturing

We would like to introduce a case where we received a request from a housing equipment manufacturer to develop a circuit board for a smart key to be used in a key system. The cover for the smart key was designed by the customer, and it was necessary to develop a circuit board that could achieve miniaturization while considering the required specifications. Additionally, the smart key required operation on a button battery, and it was essential to design for low power consumption to ensure that the battery replacement frequency would be over one year. For power saving, we utilized the microcontroller's sleep mode. Furthermore, to achieve miniaturization, we used a small-scale microcontroller and developed it without an operating system. **Our Proposals and Services:** - Equipped with a vibration sensor, it only activates when a certain level of vibration is detected. - Acting as an agent for obtaining permission for specific low-power radio stations. - Thorough noise countermeasures implemented during the circuit design and pattern design stages. - We provide consistent support from prototype development to mass production, responding to requests to consolidate outsourcing partners and reduce management workload. *For more details, please refer to the related links or feel free to contact us.*

• Circuit board design and manufacturing

We would like to introduce a case where we developed a lithium-ion battery control board to be mounted in fan-equipped wearables. The fan operation of this wearable is controlled via a smartphone, which required us to design the interface and control to enable integration with the smartphone. Additionally, due to a short development period, it was necessary to bring the prototype to completion within a short lead time, and we were entrusted with this task because our company provides consistent support in both hardware and software design. For this product specification, there is a metal (cell) near the circuit board, which could cause issues with BLE communication, necessitating countermeasures. However, we achieved stable communication by optimizing the operating mode of the BLE module. [Our Proposals and Services] - The specifications have been changed to a 12V output, and the cell connection has been modified from 2 series and 2 parallel to 4 series, optimizing the output voltage control specifications. - The software specifications on the device allow for checking the battery level via a smartphone, and we designed the circuit and board to ensure that there is no discrepancy between the actual charging/discharging amounts and the battery level displayed on the smartphone. *For more details, please refer to the related links or feel free to contact us.

We would like to introduce a case where a communication board used in an interior chair was developed. Our customer had no expertise in embedded hardware design and development and wanted to request development from a company that could handle everything from circuit design and board design to implementation in a consistent manner, so they consulted with us. In response, we conducted design work for digital circuits and boards, focusing on noise reduction and miniaturization. Additionally, there was a request to minimize the production costs of the board, so we designed it to allow for single-sided mounting. [Our Proposal/Services] - In addition to board mounting, we designed and manufactured inspection jigs to conduct board inspections. - Due to procurement issues with the BLE module planned for use, we had to use a smaller ROM capacity from the same series, which required compressing the program size, but we were able to fit it within capacity by minimizing the parts used for debugging. *For more details, please refer to the related links or feel free to contact us.

• Circuit board design and manufacturing

We would like to introduce a case where we received a request for the development of a circuit board for a key system sold under the client's own brand from a residential equipment manufacturer. It was necessary to develop a circuit board that not only controls motors but also enables communication with other circuit boards via wired connections, and allows for the recording of locking and unlocking operation history, covering all of these specifications. This circuit board controls two motors. There was a concern about operational failures due to the long physical distance between the motors and the power supply, which could lead to voltage drops and reduced current. To mitigate voltage drop, we implemented low power consumption control. We utilized our expertise in motor control to ensure the reliable operation of both motors during development. [Our Proposals and Services] - Regarding the power supply, using a one-chip power board resulted in significant power noise, so we developed a custom power supply and implemented noise countermeasures. - For collaboration with other companies' circuit boards, we adopted RS485 and RS232C communication standards, and we also implemented noise countermeasures on our circuit board to achieve stable operation. *For more details, please refer to the related links or feel free to contact us.
