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 "CCS2" is a ceiling-mounted vehicle counting sensor that employs an infrared reflection method. It can detect vehicles in both directions with just one unit, accurately counting vehicles even during traffic jams or when vehicles pass each other. Additionally, this product can be used not only for vehicle counting but also as a sensor for departure warnings. Furthermore, by using a separately sold dedicated remote control, it is easy to reset the sensor alone, switch the counting direction, and change the patterns of the departure warning timer. 【Features】 ■ Angle adjustment is possible up to ±5° ■ Can be installed in locations with high ceilings up to 4m ■ Detection area consists of 40 spots, allowing for wide-range detection ■ The display LEDs are color-coded by direction, making operation confirmation easy.

Many people may have questions like, "What can be done with IoT?" and "What is needed?" upon hearing the term IoT. Through digital communication, it is possible to obtain various information such as flow sensors, valves, circuit boards, and abnormal monitoring that were not accessible with traditional analog control. For example, by monitoring the valve opening, one can detect blockages in the equipment and identify leaks from cumulative flow. This information directly contributes to reducing downtime and improving quality through continuous long-term monitoring and knowledge-based management. Compatible models include those with digital communication via RS485, in addition to traditional analog controls like 0-5VDC and 4-20mA. (Older models such as the 58xxS, MfxxS series, SLA58xxS, and SLAMfxxS series). Even older models that do not support digital communication can be upgraded to the latest mass flow models, enabling digital communication. The dimensions between new and old models are the same, and no wiring changes are necessary. Additionally, we can provide control boxes for data collection from mass flow. This enables a "visualization" of small IoT without making large changes to the equipment.
