Analysis case of faulty switch contacts

Appearance inspection, electrical inspection, and internal observation using X-rays conducted! Introduction of analysis cases.

Due to the suspected malfunction at the switch part of the appliance that has stopped powering on, we will introduce a case study along with the work flow. First, we check for any shape changes such as swelling, cracking, or discoloration through visual observation. In the electrical check, we verify whether the malfunction can be reproduced and whether it is an open or short circuit. An internal observation using X-rays revealed that the contact terminals inside the switch had melted, scattered, and disappeared, leading to an open circuit failure. Ultimately, we will submit a report that includes the consideration of the cause. We also welcome inquiries regarding analysis after non-destructive testing, so please feel free to consult us. 【Basics of Non-Destructive Observation】 ■1: Visual Confirmation ■2: Electrical Confirmation ■3: Internal Observation with X-rays *For more details, please refer to the PDF document or feel free to contact us.

X-ray CT observation allows for the assessment of the winding condition of coil wiring! We will introduce examples of observing IC-type coils, which differ from X-ray transmission observation.

Here are some observation examples of IC-type coils. By using appropriate methods for X-ray observation, we can clearly capture the internal structure according to the purpose. In transmission observation, we can quickly detect metal foreign objects, and in CT observation, we can obtain three-dimensional images of arbitrary cross-sections, making it suitable for observations where positional information and shape are important. Unlike transmission observation, we can also assess the winding condition of the coil wiring. *For more details, please refer to the PDF materials or feel free to contact us.

X-ray fluoroscopy observation, oblique CT observation, orthogonal CT observation, etc.! Introduction of BGA solder crack analysis cases.

We will introduce a case study of BGA solder crack analysis using X-ray imaging and CT scanning. When observing the BGA connection area of a circuit board that had become electrically open using X-ray imaging, cracks were confirmed to have occurred at the BGA connection. Additionally, we examined the cracks in the solder connection area identified through X-ray imaging using oblique CT. Oblique CT provides clear planar information, but spherical shapes like solder balls and voids appear elongated in the vertical direction due to specific factors of oblique CT. While it is difficult to obtain cross-sectional information about the cracks occurring at the solder joint interface, there is the advantage of being able to observe the circuit board non-destructively.

Observation of the misalignment of the internal metal plate! This is a case study of a toggle switch observed using X-ray fluoroscopy and orthogonal CT observation.

A defective toggle switch component was found where the operating lever does not switch. Upon performing X-ray fluoroscopic observation, it was observed that the internal metal plate was misaligned, revealing the cause of the defect. In this case, the metal plate is supposed to move like a seesaw around the central terminal to switch the circuit, but due to the misalignment of the metal plate in the defective product, the lever could not switch to the opposite side, preventing the circuit from being switched. CT observation provides not only a 3D image but also arbitrary slice cross-sectional images in the X, Y, and Z directions. [Observation Case] ■ Subject: Toggle Switch ■ Observation Method: X-ray fluoroscopic observation, orthogonal CT observation ■ Cause of Defect: Misalignment of the internal metal plate *For more details, please refer to the PDF document or feel free to contact us.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without affecting the base material with heat. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

Thank you very much for visiting our company website and catalog, and for your interest in our diesel engine generators. From customer surveys, we received the following feedback as the most common requests: - I want to see the actual generators that have been installed. - I want to see the operation under actual load. - I want to hear the opinions of companies that have installed the generators. - I want to see the operating generators before making a purchase. After all, it’s understandable to be concerned about purchasing a generator without seeing the actual unit first, right? As the saying goes, "Seeing is believing..." we will be holding this tour. It is located in that area of the Kanto region where the maximum temperature exceeds 40°C during the summer. We successfully operated it again this summer, so we are confident about handling the heat (sweat)... Furthermore, it has been confirmed that it is "fuel-efficient" due to the world-leading "Scania engine" installed. This will surely help reduce daily operating costs. Please note that while we will provide kind and courteous assistance, the meeting point and dispersal will be at the site (transportation costs and other expenses will be borne by the customer), so please understand this in advance.
