Case study of switch contact failure analysis

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.

• Non-destructive testing

We undertake contract processing and manufacturing of cross-sections of various parts and materials.

At Aites, we undertake the processing of cross-sections of various components and materials, including electronic components, mounted circuit boards, semiconductors, compound semiconductors, power devices, films, resin molded products, solar panels, and LCD glass. We also conduct observations and analyses of the produced cross-sections, providing services for defect analysis and quality evaluation. 【List of Services】 ■Mechanical polishing ■CP processing ■Microtome ■FIB processing ■Analysis of semiconductor diffusion layers, etc. *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 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 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 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.

We have updated the article on the website of the semi-custom system construction "Select Beam." When planning factories, logistics warehouses, and stores, "system construction" has become an effective means of achieving cost reduction and shortening construction periods. The rationality of system construction through thorough standardization is very high, and it is adopted in many projects. However, due to the differing characteristics of each manufacturer, many business owners find themselves wondering, "Which manufacturer is suitable for our plans?" and "Is it really optimal compared to conventional methods?" In this article, we will compare and introduce the basic knowledge of the advantages and disadvantages of system construction, as well as recommend manufacturers by purpose in a ranking format. ■ Semi-Custom System Construction "Select Beam" This is a unique method by Sakura Structure, and it is a "third option" that is less expensive than system construction. It is the most suitable method for low-rise long-span buildings such as stores, warehouses, factories, and logistics facilities, as well as high-rise buildings like hotels.

"Because the ground is poor, we have no choice but to use a structural slab." Such fixed notions of "over-design" unnecessarily drive up construction costs. In large space buildings such as warehouses, factories, and stores, the choice of floor slab type is one of the most significant variables affecting construction costs. What is important is to compare and verify the advantages and risks of each type, and to derive the optimal solution that is "suitable for the purpose" for the entire building. By reading this content, you will understand the following points: - Characteristics of the five main construction methods with different support forms - Recommended situations for adoption - Cost comparison examples of floor slabs "I am struggling with the dilemma of floor settlement risks and costs on weak ground." "I want to know the optimal solution for the site without being tied to a specific construction method." Construction companies and general contractor representatives facing such issues are encouraged to take a look.

Our company will be exhibiting at the "Hokuriku Technology Exchange Techno Fair 2026." Dates: October 23rd, 10:00 AM - 5:00 PM October 24th, 10:00 AM - 4:00 PM Venue: Fukui Prefectural Industrial Hall We look forward to your visit.
