    Recently, the market for electric vehicle batteries and self-driving cars is growing. If the current limitations of battery testing for electric vehicles are overcome through 3D X-rays, accidents such as battery ignition will be greatly reduced."

    Competition between companies to preempt markets for electric vehicle batteries, which have been growing rapidly recently, is fierce. According to global market research firm IHS Markit, the size of the electric vehicle battery market is expected to grow by 25% annually every year to reach 160 billion dollars (about 182 trillion won) in 2025. Some companies are keeping a close eye on the growth of the market. It is SEC, which has the largest share of X-ray inspectors for South Korean industries.

    On October 29, he and the Innobiz Association visited the SEC headquarters and production facilities located in Gwonseon-gu, Suwon, Gyeonggi Province. SEC produces inspection equipment using X-rays and injection electron microscopes, which are equipment for observing and measuring surface information of materials. As of last year, sales stood at 34.8 billion won and are currently "strong and small companies" with 178 executives and employees. In particular, it was named "100 Small and Medium Venture Businesses" by the Ministry of Small and Medium Venture Business last year in recognition of its competitive edge in equipment technology.

    On the first floor of SEC's headquarters, there was a production process for industrial X-ray inspectors. Entering the production facility, industrial X-ray inspectors ordered were waiting in a row for the engineer's touch.

    "We succeeded in localization and commercialization by securing original technology for X-ray tubes that relied on all imports and developing 10 models," said CEO Kim Jong-hyun of SEC. "We have secured cost reduction and price competitiveness through internalization and in-house production, and are preparing for reverse exports to Japan and Germany."
    The industrial X-ray inspection machine business is a key business for the company. In fact, the proportion of sales of industrial X-ray inspectors currently accounts for 65 percent of annual sales of the SEC. SEC is planning to expand its business to secondary batteries such as electric vehicle batteries, instead of staying only for inspection on electric and electronic components and semiconductors. This is because batteries have become essential as development of future cars such as electric vehicles and self-driving cars is speeding up. According to SNE Research, the supply of batteries for electric vehicles, which remains at the 500 gigawatt hour (GWh) level as of this year, is expected to expand to 3,000 GWh in 10 years. The market size, which stood at $33 billion in 2018, is also expected to increase to $350 billion in 2030.

    In addition, in the case of future cars, the number of electrical and electronic components such as semiconductor chips and modules increases by more than 1,000 compared to existing internal combustion locomotives.

    In particular, CEO Kim explained that if the current 2D-level X-ray test is expanded to 3D, it will dramatically prevent sudden accidents in cars or electric vehicle battery fires.

    "In the case of domestic electric vehicles, some manufacturers have not conducted X-ray tests or are only conducting 2D X-ray tests," CEO Kim said. "I am confident that if defects are tested before selling them using 3D technology, battery fire accidents will be greatly reduced."

    "The Galaxy Note 7 was eventually discontinued due to a battery explosion, but as a countermeasure, we announced that we would conduct another X-ray test once the X-ray is completed," he said. "The reason why there is no more problem with battery ignition on the mobile phone is because we are currently testing it twice after the cell."
    Currently, the hybrid open tube of the set can obtain images without any residual images during 3D CT scans and 3D CT scans at the world's highest speed (3.5 seconds). In addition, Sek's 4 high AXI system also has the world's best inspection speed and precision using 3D and 2D, and is equipped with deep learning-based artificial intelligence inspection algorithms.

    SEC plans to expand the supply of the product and expand the production line by the next 10 years as demand for X-ray examination equipment continues to occur and demand for 3D CT examinations is expected to explode. Through this, it is calculated that it will raise annual sales of KRW 30 billion this year to KRW 80 billion next year and achieve KRW 100 billion in 2022. At the same time, the company is planning to become a company that survives for more than 100 years by achieving 50 percent of sales of parts modules by 2030 by putting efforts into parts (module) businesses.

    "Since next year marks the 30th anniversary of its establishment, it will contribute to securing stability of future cars such as batteries for prepositions and electronic equipment parts for self-driving cars based on excellent technologies that have been accumulated," CEO Kim said. "We will grow from parts and equipment industries related to X-ray to a world-class company and grow into a company that survives for more than 100 years."

  • Visitors to the SEC Demo Center can shoot and experience X-ray equipment for each application, and can also check various samples directly through PCT equipment capable of large die casting. SEC is also providing a non-face-to-face service that shoots X-ray images and delivers reports according to requests for all domestic and foreign customers who are difficult to move or visit due to corona.

    Applications that can be photographed are Automotive, Mobile (Smart Device), Semiconductor (Wafer level, Substrate, PKG chip), Li-ion Battery, SMT (QFN, QFP, PCB, BGA), etc. The world's fastest high-resolution 3D CT AXI'X-eye 6300 AXI' in detail, the 2D / 3D inspection equipment'X-eye160NCT' that enables precise analysis and mass production inspection, and the 2D inspection equipment'X' that enables simple analysis and mass production inspection. -eye5000N', large die casting inspection and high-energy X-ray inspection equipment'PCT' of up to 450kV will be released.

    In addition, you can meet various equipment of the check, including 'NANO-CT', SF160FCT, and 6100AXI, which tests fine defects of several μm sizes occurring in TSV and Micro-bump, and in particular, you can check the CT images of Li-ion Battery. In addition, customers who need to be photographed, such as defect inspection, or those who want to test the performance of the equipment themselves, can take samples according to their requirements. Demonstration services for each field can be used as tabletop SEM and linear accelerators (LINAC) are being developed and produced. Not only in Korea, but also in China, European and U.S. branches are operating demonstration centers built with some models of X-ray equipment and Tabletop SEM.

    "The Demo Center has accumulated know-how for more than 20 years, and it is a space where you can experience the unique technology of the Sekman."We expect that we will be able to provide more necessary inspection equipment to our customers by establishing close cooperation with the site based on customer opinions visiting the center," he said.

    Meanwhile, since its foundation in 1991, CEC has been building the foundation of e-beam inspection equipment in Korea based on its competitiveness against global companies by localization of core component X-ray generating devices. By introducing products in X-Ray, SEM, and LINAC, it was selected as 'Materials, Parts, and Equipment Strong Companies 100' organized by the Ministry of SMEs and Startups in 2019.

BEWARE - Special Warning Notice about ExpoGuide and FAIRGuide

With the ongoing solicitations, SEMI would like to continue to alert you with questionable professional practices perpetrated against exhibitors by FairGuide.com (Austria) and Expo Guide (Mexico), Event Fair - The Exhibitors' Guide with their misleading directory services. There may be others that we are not aware of and are hence not named here. 

These companies provide legitimate exhibition guides aimed at exhibitors across the globe offering online listing services. They use a form which resembles and organizer's free catalogue listing service, inviting exhibitors to complete the form for an entry in an on-line directory. Unsuspecting exhibitors who sign and return the form are then contracted into a three-year, non-retractable agreement, which could cost the exhibitor a significant amount of money, with very limited foreseeable benefits. The details are often available on the form itself, but are often too small and insignificant to be noticed. It is always wise to really the small print before signing a contract, and if the information is impossible to read then the contract should not be signed. These publications have no connection with SEMI or any of our events, and it is important that all companies are made aware of this. 

Should you receive any communication from the Expo-Guide and Fairguide.com or related company, please IGNORE THEM COMPLETELY and DO NOT COMMUNICATE WITH THEM IN ANY WAY.
