Currently, motors are widely used in precision equipment fields such as computers and HDDs. We will introduce the principles and examples of use of the technology called "PWM control," which is used for motor control. PWM is one method of controlling power using semiconductors. It is a type of pulse density modulation (PDM), and a PDM with a constant frequency is called PWM. PWM can be controlled by repeating the ON and OFF of a switch, and this high-speed switching generates a pulse waveform. By changing the duration of the pulses, it controls the power supplied to the load. PWM control has excellent controllability. For example, by controlling the rotation speed of a cooling fan motor, the speed can be adjusted in response to the temperature of the object being cooled, thereby controlling the cooling performance. (Without control, the rotation speed remains constant, which can lead to excessive cooling even at low loads.) Additionally, there is the advantage of increased quietness, as the minimum rotation speed is achieved at low loads, reducing the noise generated by the rotation. Our company applies various technologies and offers application development in a variety of fields. Please feel free to contact us.

In recent years, the technology of electronic devices has significantly improved, leading to frequent concerns about noise countermeasures. This time, we will explain the components and basic knowledge necessary for EMC measures (noise countermeasures). EMC stands for "Electromagnetic Compatibility," which is almost synonymous with noise countermeasures. Noise exists not only in sound waves but also in "radio wave noise," and addressing this radio wave noise is what EMC measures are about. In modern life, electrical and electronic devices are indispensable, from communication devices like smartphones and USBs to production equipment in factories. However, these electronic devices can malfunction or fail due to electromagnetic noise, potentially leading to serious accidents that could endanger lives. Therefore, EMC measures and noise countermeasures are essential for electronic devices. EMC measures can also be implemented using components. Method 1: Shielding Method 2: Filtering Method 3: Grounding To effectively implement EMC measures, it is important to approach the issue from various aspects, including design. Our company develops hardware with designs that are resistant to noise and static electricity, ensuring durability. Please feel free to contact us!

In recent years, the adoption of serial communication has been increasing due to advantages such as space-saving, cost reduction, and high performance. Serial communication uses one or two signal lines to send data sequentially, transmitting one bit per clock cycle. Although there were concerns regarding speed, high-speed serial communications like USB and PCIe have since become widespread. Serial communication can be broadly classified into two types: asynchronous and synchronous. Asynchronous types include I2C, JTAG, and UART, while synchronous types include USB and PCIe (high-speed serial communication). High-speed serial communication features clock, data, and recovery functions, excelling in terms of speed. <Serial Communication Physical Layer Standards> 1. RS232-C 2. RS422-A 3. RS485 4. Ethernet In industrial equipment, RS485 is the most commonly used. This standard allows multiple devices to be connected on the same data line, ensuring real-time control, making it suitable for industrial applications. Our company offers application development in various fields. Please feel free to contact us!

In recent years, the demand for food safety has increased more than ever, making hygiene management an important issue. This time, we will explain the initiatives of HACCP and how to operate it efficiently. HACCP (Hazard Analysis and Critical Control Points) is the international standard for food hygiene management, and it has been mandatory in Japan since June 2020. Below are the five meanings of HACCP: 1. Hazard 2. Analysis 3. Critical 4. Control 5. Point HACCP involves monitoring and recording whether hygiene management is being maintained throughout all processes. This allows for the suspension of shipments of products manufactured under conditions that do not meet standards and enables smooth tracking of issues when problems arise. Since operations involve time-consuming tasks such as record-keeping and verification, it is desirable to carry them out efficiently. For example, services that allow for easy recording using smartphones or tablets, and apps that automatically record temperatures, are gaining attention to reduce the burden on employees. Our company offers contract development of cloud systems that assist with HACCP record-keeping and storage. If you are at all interested, please feel free to contact us!

Board assembly refers to the process of connecting electronic components to a printed circuit board (PCB) through soldering (component mounting) to form an electronic circuit. The closer the mounting distance between components, the higher the functionality of the control board. There are two types of mounting methods, which vary depending on the electronic components: ■ Through-hole mounting method Insert electronic components into holes (through-holes) and perform soldering. ■ Surface mount method Connect components to the pads on the surface of the printed circuit board with solder. Many companies may handle circuit design and board design in-house while outsourcing component procurement and board assembly for control boards. When choosing an outsourcing manufacturer, the key points are: 1. They have well-equipped manufacturing facilities. 2. They listen to the desired performance and components you want to use. Additionally, we recommend factory tours and site inspections. This will not only help you understand the machines in use but also give you a sense of the workplace atmosphere. A team with good teamwork can be expected to produce high quality and smooth production. Our company offers a comprehensive service from board development to assembly, and we provide proposals after thoroughly understanding your specifications and applications.

Temperature control is a system designed to maintain a set temperature consistently. For example, in air conditioning, the fan speed and airflow are adjusted to reach the set room temperature. This mechanism is used in many household appliances such as refrigerators, microwaves, and water heaters. In industrial products, printed circuit boards, which are the heart of electronic devices, are used, and automatic control of temperature and other factors is designed to operate based on signals emitted from them. There are various types of temperature control, with the most representative being ON-OFF control. This is a simple control method where the switch is turned OFF when the set temperature is reached, and turned ON again when the temperature drops, as seen in electric kotatsu. However, since it can only operate in a binary manner (either 0 or 100), it struggles with delicate temperature adjustments and has the drawback of being prone to "overshoot." To improve the instability of ON-OFF control, proportional control was developed, characterized by its ability to adjust output in stages. By changing the motor's movement according to the temperature difference, smooth temperature control similar to that of air conditioning becomes possible. It is important to differentiate between the simple ON-OFF control and the more stable proportional control based on the application, as understanding this can help improve product quality and stability.

Electronic devices that are essential for daily life. Almost all of them are equipped with microcontrollers, and their functions and operations are determined by software. Software development is the process of embodying "customer needs" and "marketing analysis and goals" into software products, referring to the series of tasks involved in developing the contents of software such as systems and applications. Depending on the differences in "what is being developed," it can be broadly classified into three types: ◆ System Software ◆ Application Software ◆ Embedded Systems The flow (process) of software development is as follows: 1. Sales to companies 2. Specification meetings 3. Requirements definition 4. System design and development 5. Debugging 6. Delivery There is a range of development costs depending on the scale of the system, but if you choose a contractor based solely on cost, there is a risk of failure. Therefore, it is recommended to entrust the development to a reliable company that can meet your conditions. At Nippo, we have experienced designers and developers in various fields focusing on temperature, humidity, communication, memory, and control, and we develop software tailored to our customers' needs.

In recent years, the electric industry has been demanding harsh conditions from the market, such as "high quality, high functionality, and short delivery times," making it necessary to choose manufacturing and assembly manufacturers that fit the company’s needs. Therefore, it is important to find manufacturing and assembly manufacturers that meet the conditions of "high quality, high functionality, and short delivery times." The differences between the production forms of circuit board development—EMS, OEM, and ODM—are as follows: ◆ EMS The contracted company handles everything from design to logistics on behalf of the commissioning company. ◆ OEM The commissioning company conducts product design, while the contracted company only handles manufacturing. ◆ ODM The contracted company conducts product design and manufacturing in consultation with the commissioning company. Even if the concept and design are not finalized, ODM development and manufacturing is recommended because it allows for production and sales with the cooperation of the contracted manufacturer. Nippo offers ODM development (proposal-type ODM) that covers everything from product design to product development. Our sales and technical staff will listen to your requests and concerns and propose a solution plan. Please feel free to contact us!

A printed circuit board (PCB) is a general term for a "printed circuit board" that has electronic components such as ICs and resistors mounted on an insulating printed wiring board. Its main role is to provide electrical connections between the electronic components that make up the circuit. By efficiently connecting wiring in one place, it contributes to miniaturization, increased productivity, and cost reduction. There are two main types of printed circuit boards: ◆ Rigid boards These are made using hard insulators such as epoxy resin and are also called rigid substrates. They have the advantage of being strong, making it easier to mount electronic components. ◆ Flexible boards These are characterized by being thin and flexible, as they use plastic film as the substrate. They are used as connecting cables for movable parts of electronic components and for connections between boards or units. To manufacture a printed circuit board, it is necessary to implement all the electronic components used in the electronic circuit and design the patterns through which current will flow to connect each electronic component (artwork). Nippo offers a wide range of services, from the design of electrical and electronic circuits to the design of printed circuit boards and the construction of control systems.

Control boards are essential during the development of electronic devices and equipment. If your company does not have a development department with expertise, you can outsource the manufacturing of control boards to manufacturers that specialize in this area. Recently, the number of overseas manufacturers offering contract manufacturing for control boards has increased, providing many options for outsourcing, which can sometimes lead to confusion. In this article, we will introduce the advantages and disadvantages of manufacturing with domestic control board manufacturers. ■ Advantages Many domestic manufacturers support the entire process from specification meetings to delivery and after-sales follow-up, allowing you to proceed with development with peace of mind. ■ Disadvantages Due to relatively high costs, when it comes to manufacturing a developed board in large quantities at a low price, overseas manufacturers tend to be more cost-effective. Among domestic manufacturers, there are companies like ours that offer a comprehensive service from circuit design of control boards to embedded software development and manufacturing. If you can find a manufacturer that provides integrated outsourcing, you can delegate everything from the case that houses the control board to the surrounding electrical wiring, thereby reducing labor hours. If you have any interest, please feel free to contact us. We will provide you with the best proposal tailored to your needs!

A touch panel monitor (touch panel display) is a device that allows users to operate it by directly touching the display screen, and it is utilized in various situations such as ATMs. This time, we will introduce the types of touch panel monitors, how to choose them, and their advantages. There are two types of touch panel monitors based on the method of detecting screen touches: "capacitive" and "resistive." ■ Capacitive Supports flick operations. Example: Smartphones, etc. ■ Resistive Cannot perform flick operations but can be introduced at a lower cost. Example: Car navigation systems, ATMs, etc. The advantages of adopting a touch panel monitor are as follows: - It allows for screen switching, enabling the display of a large amount of information. - It can display graphs and photos or incorporate user manuals. - When making model changes, it is relatively easy to modify colors, font sizes, display names, and more. Our company develops applications that combine touch panel monitors with control boards. If you have any interest, please feel free to contact us!
