Generally, "shipping inspection," which occurs in the final stage just before shipment to the market or customer, is a very important inspection that arises during the manufacturing process of products. For products, it is judged as "compliant" or "non-compliant," and for lots, as "pass" or "fail." There is a possibility that quality may deteriorate during subsequent packaging, transportation, and storage periods. In principle, products should go through "incoming inspection" and "process inspection" during the processing and manufacturing stages. However, during packaging, transportation, or storage, there may be issues with quality due to time-related deterioration or human factors. Shipping inspection is an important check that further scrutinizes quality and serves as the last line of defense to prevent defective items from being distributed.

PSE (Product Safety Electrical Equipment) is a regulation aimed at ensuring the safety of electrical equipment and electrical components used in Japan. The PSE mark certifies that these electrical products comply with safety standards based on Japan's Electrical Appliance and Material Safety Law (DENAN Law). This mark guarantees that electrical products are properly designed, manufactured, and can be used safely. Even for electrical equipment and components manufactured overseas, obtaining the PSE mark is necessary for domestic sales. Self-inspection refers to the process of verifying whether the product maintains the safety standards established when it obtained PSE certification for each production run. This must clear items such as "product functionality verification," "safety verification," and "record keeping." Our company, which specializes in inspection services, assists in confirming whether the product maintains the safety standards established when it obtained PSE certification through a process called "pre-shipment inspection." *For more detailed information, please refer to the related links.

Electronic components and circuit boards used in precision machinery undergo various inspections before manufacturing and assembly, with only the good products being incorporated into the final product. However, during the long inventory period from manufacturing to shipping, or in cases where manufacturing plants are overseas and transportation takes time, the risks of defects caused by "aging changes" or "vibration and shock" cannot be completely eliminated. In fact, manufacturers have indicated that if there are abnormalities in the internal settings of the product, there may also be some abnormalities in the circuit board itself. Therefore, pre-shipment inspections are very effective in preventing the risk of products with potential defects in the circuit boards from entering the market. Our company supports your business with high-quality and meticulous product inspections, leveraging the extensive experience and know-how gained from many years of calibration, repair, inspection, and testing of electronic devices, measuring instruments, and precision machinery.

To prevent electric shock accidents and fires, electrical products need to be tested for insulation resistance. This is particularly important for products intended for general households, as they are often handled and installed by individuals without electrical knowledge. The insulation resistance test involves applying a voltage that is typically 10 to 20 times higher than normal to the areas that should be insulated for a specified duration, and checking whether the insulating material causes insulation breakdown. Insulation breakdown is a phenomenon that occurs when the strength of the electric field applied to the insulator exceeds a certain value, causing a rapid decrease in electrical resistance and allowing electricity to pass through. *For more detailed information, please refer to the related links.

The other day, when I plugged and unplugged a USB-AC adapter used for work into an outlet, the part at the base of the plug came off completely, which was very dangerous. The USB-AC adapter that broke at the base was used for the first time after purchase, so I went to the store right away and was able to exchange it for a new one immediately, allowing me to resume the planned work shortly thereafter. This time, I would like to reflect a bit on this matter. *For more details, you can view the related links. For more information, please feel free to download the PDF or contact us.*

This time, we will introduce the inspection of measurement device components using a constant temperature chamber. The inspection conducted this time was on a "temperature sensor" that measures temperature. A commonly used method for checking the integrity and functionality of sensors is to create a pseudo-measurement environment and actually operate the sensor within it. In the case of a temperature sensor, if it shows the same temperature of 25°C in that environment, we can determine that the product is good. However, maintaining a constant temperature in a room with air convection is very challenging. The fact that manufacturers promote their air conditioners with points like "we evenly heat (or cool) your room" can be seen as a reflection of the difficulty in maintaining a constant temperature indoors. *For more detailed information, you can view it through the related links.

In the inspection of plastic parts, the main inspection conducted by the shipping inspector is "visual inspection." "Visual inspection" is an important process in quality control within the manufacturing industry. In addition to "visual inspection," which is determined by information obtained through "sight," there is also "sensory inspection," which utilizes the five senses of humans, including "hearing," "touch," "smell," and "taste." In the inspection of products and parts, the sense of touch, particularly the feeling in the fingertips, is utilized as an important source of information, second only to sight, when inspecting appearance and shape. *For more detailed information, please refer to the related links. Feel free to contact us for further inquiries.*

Our shipping inspectors have handled various types of measuring instruments, such as "dew point meters" that measure the moisture content in the air, "oxygen meters" that can analyze sample gases, and "flow meters" that measure the flow of gases and liquids. Each measuring instrument has differences in models and intended use, so there are naturally variations in details. However, there are many common shipping inspection items for measuring instruments, such as "appearance inspection," "insulation resistance testing," and "internal setting confirmation," which are essential for the instruments to demonstrate their quality, performance, and product accuracy. *For more detailed information, please refer to the related links. Feel free to contact us for further inquiries.*

A printed circuit board (PCB) refers to a general term for "printed wiring boards," which are formed with conductive metal in a circuit pattern on an insulating board, and "printed circuit boards," where electronic components such as IC devices containing semiconductors and resistors are mounted through soldering. Visual inspection, used as a shipping inspection for printed circuit boards, is conducted after the manufacturing of printed wiring boards and after the mounting of electronic components on printed circuit boards. The types of defects that occur during PCB manufacturing are diverse, and it is necessary to visually inspect the complex and intricate shapes of the mounting surfaces from multiple angles. Therefore, visual inspection to confirm defects and faults in printed circuit boards by human eyes remains an indispensable inspection method, even in the current era of increasing mechanization. *For more detailed information, please refer to the related links.
