Case study of switch contact failure analysis

アイテス アイテス
Since a malfunction was suspected at the switch section of the appliance that would not power on, we will introduce analysis cases 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. Internal observation using X-rays revealed that the contact terminals inside the switch had melted, scattered, and disappeared, resulting in an open circuit failure. Ultimately, we will submit a report that includes the consideration of the cause. We also welcome inquiries regarding analysis consultations after non-destructive testing, so please feel free to contact us.

Analysis case of faulty switch contacts

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

Since a malfunction was suspected at the switch part of the appliance that would not power on, we will introduce analysis cases 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 confirm whether the malfunction can be reproduced and whether it is an open or short circuit. Internal observation using X-rays revealed that the contact terminals inside the switch had melted, scattered, and disappeared, resulting in an open failure. Ultimately, we will submit a report that includes an analysis of the cause. We also welcome inquiries regarding analysis consultations after non-destructive testing, so please feel free to reach out. 【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 fluoroscopy and CT examination device 'Observation case of IC type coil'

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 examples of observations of IC-type coils. Through X-ray observation, we can clearly capture the internal structure by using methods suited to the purpose. In transmission observation, we can quickly detect metal foreign objects, and in CT observation, we can obtain three-dimensional images of any cross-section, 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 and CT examination equipment: Case study of BGA solder crack analysis

X-ray fluoroscopic 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 observed 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. [Analysis Cases] ■ X-ray imaging observation ■ Oblique CT observation ■ Orthogonal CT observation ■ Cross-sectional observation *For more details, please refer to the PDF document or feel free to contact us.

[Observation Case] X-ray Observation of a Toggle Switch

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

A defective toggle switch component was found where the operating lever does not switch. As a result of 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 in the defective product, the metal plate is misaligned, preventing the lever from switching to the opposite side and thus making circuit switching impossible. CT observation provides not only 3D images 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.
