Analyst Viewpoint: Strategic Alliances and Cybersecurity-Driven Testing to Define Market Leadership

According to analysts, the next decade will intensify competition among leading electronic testing service providers. Market leaders are expected to invest extensively in product development, strategic partnerships, and mergers & acquisitions, aiming to enhance service offerings and strengthen their global footprint. A defining driver will be the rising need for cybersecurity in electronics, especially as IoT and connected devices expose manufacturers and consumers to evolving cyber threats.

Companies are actively expanding capabilities to include cybersecurity audits, penetration testing, vulnerability assessments, and advanced performance simulations. However, the sector faces challenges such as the need for continuous technological upgrades, cost pressures, and intense market competition. Players that proactively integrate AI-driven testing systems, automation, and advanced analytics will be positioned to secure a dominant share.

Market Overview: Growth Driven by Innovation, Testing Diversity, and Digitization

Electronic testing services encompass a broad suite of solutions designed to ensure the reliability, accuracy, and functionality of electronic products. Core services such as In-Circuit Testing (ICT), Functional Testing, and Automated Optical Inspection (AOI) address different phases of product validation and quality assurance. The expansion of IoT applications, widespread digital transformation, and integration of smart technologies are increasing the need for holistic, end-to-end testing frameworks.

The integration of AI, machine learning, and cloud computing into testing platforms is expected to further enhance test automation, reduce human error, and improve diagnostic accuracy. As electronics become more advanced, testing service providers must adopt innovative methodologies that support faster turnaround times and complex system validations.

Increasing Complexity of Electronic Devices Fueling Market Demand

Electronic devices today serve multifunctional roles and integrate multiple layers of hardware, software, sensors, and data-driven features. From industrial machinery and medical devices to smartphones and EV components, the rise in device complexity significantly increases the demand for sophisticated testing services.

A notable development highlighting this trend occurred in October 2022, when SGS SA inaugurated an advanced electronics and automotive testing facility in Chakan, Pune, India. The facility features specialized labs dedicated to metallurgy, polymers, environmental simulation, airbag deployment, dynamics testing, and EMC/EMI assessments-showcasing the growing demand for comprehensive testing ecosystems.

Emerging technologies like 5G, AI-driven processors, and IoT-enabled modules further complicate the testing landscape. These technologies introduce new challenges in interoperability, data handling, real-time processing, and cybersecurity. As a result, electronic testing service providers are expanding offerings to include simulation testing, performance benchmarking, electromagnetic compatibility testing, and cybersecurity compliance solutions.

Rise of IoT and Connected Devices Accelerating Industry Growth

The global proliferation of IoT devices is one of the most impactful forces reshaping the electronic testing services market. IoT has penetrated virtually every major industry-smart homes, smart cities, telemedicine, industrial automation, autonomous vehicles, logistics, energy management, and more.

This interconnected environment demands flawless device functionality, secure communication, and compatibility across multiple platforms. ETS providers are therefore required to deliver extensive testing solutions, covering areas such as wireless connectivity, protocol compliance, battery performance, environmental durability, and network security.

The rise of IoT has coincided with increasing cyberattacks targeting connected device networks. Manufacturers are compelled to invest in rigorous security testing to ensure user safety and data protection. ETS vendors now offer comprehensive tools for security penetration testing, vulnerability scanning, and risk assessment, enabling companies to safeguard their digital infrastructure.

By meeting these rising requirements, testing providers play a pivotal role in enabling the secure and seamless deployment of IoT solutions worldwide.

Services Segment: In-Circuit Testing Retains Strong Demand

The services segment in the electronic testing industry is diverse, with In-Circuit Testing (ICT) capturing a notable portion of the market due to its ability to identify manufacturing defects early in the production cycle. In 2024, ICT accounted for 28.4% of global market share, and it is anticipated to grow at a moderate pace of 4.5% during the forecast period. ICT remains essential for validating solder joints, component placement, and circuit integrity, especially in high-density PCB architectures.

Regional Outlook: East Asia Leads Global Market Growth

East Asia continues to dominate the global electronic testing services market, holding an impressive 60.0% share in 2024. The region is home to several of the world's largest electronics manufacturers and is the epicenter for smartphone, semiconductor, computer, and consumer electronic production.

Countries such as China, Japan, and South Korea benefit from strong manufacturing ecosystems, large investments in R&D, and robust supply chains. With growing regulatory emphasis on product quality, safety, and compliance, East Asia is projected to grow at a CAGR of 4.1% through 2035.

Key Players and Market Developments

The competitive landscape features global leaders such as Benchmark Electronics, Celestica, Fabrinet, FLEX, Jabil, Sanmina, SGS SA, IMI, PEGATRON, Plexus, and Zollner Elektronik AG, among others. These companies continuously invest in expanding laboratories, acquiring technology-driven firms, and strengthening digital testing solutions.

For instance, AIM Photonics introduced advanced opto-electronic testing services in May 2023, broadening the scope of testing for photonic integrated circuits (PICs) alongside traditional electronic ICs.

Conclusion

With a projected value of US$ 153.6 Bn by 2035, the electronic testing services market is set for robust growth. The increasing complexity of electronics, rapid adoption of IoT, and demand for secure and reliable devices will push companies to seek advanced testing solutions.
