Insights from White Horse Laboratories, July 2025
In July 2025, White Horse Laboratory continued to provide comprehensive testing services for a wide range of electronic components and manufacturers worldwide. This month’s report highlights key trends, quality risks, and actionable insights to help industry stakeholders make informed decisions.
Key Insights at a Glance
Overall Quality Trends
The overall market quality remains robust, with 84.7% of tested samples deemed acceptable. However, the proportion of unacceptable results rose to 9.5%, up from 8.1% in June, signaling potential risks that warrant attention. Additionally, 5.7% of samples were flagged for further analysis, indicating concerns that could impact long-term reliability.
Device Categories: What Was Tested?
Last month, FPGAs, memory devices, and MCUs were among the most frequently tested components, reflecting their critical role in high-performance computing, communication infrastructure, and industrial control. These categories are in high demand due to the rapid expansion of AI, 5G networks, and smart manufacturing.
Notably, power-related components, particularly rectifiers, emerged as a significant outlier, topping the failure rate rankings. This trend suggests potential inconsistencies in production or supply chain disruptions affecting certain batches.
Device Types with Highest Failure Rates
- Rectifiers led the failure rate rankings, followed by discrete semiconductor products and passive-resistor components.
- DSP chips and converters also showed elevated failure rates, though not as pronounced as rectifiers.
Manufacturer-Specific Trends
- Panasonic Electronic, TDK Corporation, and Lattice had the highest failure rates among manufacturers, though it’s important to note that this does not reflect their overall quality but may indicate batch-specific issues.
- Mainstream brands like Texas Instruments, Analog Devices, and Infineon maintained stable performance, reinforcing their reputation for reliability.
Testing Methodologies: What’s Keeping Components in Check?
External Visual Inspection (EVI) remained the most common test, accounting for 29.1% of all inspections. This underscores the importance of identifying surface-level defects and irregularities as the first line of defense against counterfeit or substandard components.
- X-ray inspection (18%) and functional testing (17.4%) were critical for detecting internal defects and verifying functionality.
- Decapsulation and die analysis (16.1%) provided deeper insights into component integrity, particularly for high-risk devices.
Supply Chain Diversity and Risks
The data reveals a diverse supplier landscape, with 37.2% of tested devices coming from over 200 different brands. While this diversity supports market resilience, it also introduces variability in quality.
- Texas Instruments dominated the tested sample pool, followed by Analog Devices, Xilinx, Infineon, and STMicroelectronics.
- Smaller manufacturers contributed significantly to the “Others” category, highlighting the need for rigorous vetting, especially for less-established suppliers.
Actionable Recommendations for Procurement Teams
- Prioritize Testing for High-Risk Components: Given the elevated failure rates in rectifiers, DSP chips, and passive components, we recommend enhanced scrutiny during procurement, particularly for power-related devices.
- Leverage Comprehensive Testing: Utilize a combination of EVI, X-ray, and functional testing to mitigate risks early in the supply chain.
- Monitor Supplier Performance: While mainstream brands generally perform well, batch-specific issues can arise. Regularly review supplier quality data and consider diversifying sources for critical components.
- Stay Ahead of Emerging Risks: The increase in unacceptable results suggests accumulating risks. Proactive testing and supplier audits can help identify issues before they impact production.
