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.

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.

Hotron Inc. has launched its new product, the "Vehicle Count Sensor CCS3"! This product is a ceiling-mounted sensor that combines infrared and radar technology. It reliably detects vehicles in both directions with a single unit, accommodating traffic during congestion and vehicle passing, thus achieving efficient occupancy management in large parking lots. Additionally, it can be utilized for exit warning purposes in addition to vehicle counting, contributing to the safe and smooth operation of parking facilities. 'Features' - Improved detection performance against changes in road surface during rainy weather by using both infrared and radar. - Equipped with IP67 waterproof and dustproof performance, making it effective even in salt damage areas. - Various settings can be configured from a dedicated app (for Android devices), with current settings easily visible at a glance. - The base dimensions are the same as the previous model "CCS2," allowing for smooth replacement of existing equipment. *For more details, please refer to the product information, catalog download, or contact us.*

Recently, Intertek Certification AB, the Swedish subsidiary of Intertek, has been accredited by the Swedish national accreditation body Swedac as a verification body for the EU Carbon Border Adjustment Mechanism (CBAM). According to Swedac's announcement, this is the first CBAM accreditation for a verification body in Sweden. This accreditation covers six sectors: cement, steel, aluminum, fertilizers, hydrogen, and electricity, and Intertek Certification AB will provide third-party verification services for embedded emissions associated with the manufacturing of CBAM-covered products based on the scope of accreditation. CBAM is a system that reflects the carbon price on greenhouse gas emissions associated with the manufacturing of certain products imported into the EU, requiring targeted companies to properly calculate and report their greenhouse gas emissions data and comply with third-party verification. Intertek Certification Co., Ltd. supports CBAM compliance in collaboration with accredited entities and global expert teams as the contact point in Japan. If you have any inquiries regarding third-party verification or related services, please feel free to contact us.

On October 23, 2026, Brent crude oil futures closed at \$116.72 per barrel. Considering the situation in the Middle East and transportation risks, we introduce points for reviewing the procurement and costs of cleaning agents in our HP article. It is important to check not only the purchase price of thinners and parts cleaners but also the usage amount, working hours, and waste liquid disposal costs. The article provides guidance on how to evaluate the water-based cleaning agent SEA’S7 as an alternative candidate, as well as the application page for tool and jig cleaning. You can consider switching from processes that can be changed by comparing the impact on materials, cleaning quality, rinsing and drying, and compatibility with subsequent processes. The effectiveness and cost vary depending on usage conditions. Please feel free to consult us about comparative testing.
