April’s quality data reflects a dynamic shift in priorities across the electronics supply chain—a modest decline in test pass rates, a notable increase in non-testing services, and continued diversification in both components and suppliers. Here’s a detailed look at the trends emerging from White Horse Laboratories’ latest analysis.
Testing Services: EVI Still Leads, Packaging Gains Ground
The most frequently performed service in April was once again External Visual Inspection (EVI), accounting for 23.5% of all activities, underlining the industry’s focus on detecting cosmetic and labeling anomalies early in the process.
Notably, packaging and logistics services – including reel, tray, and tube conversions, as well as related shipping preparations – jumped to 19.3%, making it the second most requested service. This rise suggests a growing demand for supply chain readiness and handling assurance, alongside component validation.
Other core testing types included:
- Functional Testing (15.3%)
- X-ray Inspection (12.7%)
- Decapsulation, Solderability, XRF, and HCT Testing together accounted for a smaller share, but remain essential in targeted cases.
Testing Outcomes: Stable, but Slightly Down
Compared to previous months, the pass rate dropped slightly, while the share of components requiring additional evaluation remained consistent, highlighting the importance of follow-up testing in borderline cases.
Most Tested Components: Memory Leads the Way
In terms of component types, Memory ICs topped the list at 7.8%, up from 5.8% in March, potentially reflecting restocking efforts or increased demand in storage-intensive applications.
Other frequently tested categories included:
- FPGAs (7.2%)
- Capacitors (5.0%)
- Resistors (4.6%)
As in previous months, more than one-third of tested components fell into the “Other” category, illustrating the breadth and variety of parts passing through the lab each day.
Brands in Focus: Analog Devices Takes the Lead
This month saw a change at the top: Analog Devices (ADI) overtook Texas Instruments as the most tested brand, reaffirming its strong presence in analog, mixed-signal, and DSP technologies.
Following ADI were:
- Texas Instruments
- Xilinx
A less frequently seen brand also caught attention: Avago Technologies (Broadcom), a specialist in analog semiconductor design, appeared prominently in April’s testing activities, an indication of its rising market presence.
As with components, 36.6% of tested brands were grouped under “Other,” representing a wide array of small and mid-sized global semiconductor suppliers. This reflects the growing importance of niche brands and the increasing complexity of global sourcing strategies.
Failure Trends: Embedded Controllers Raise Concerns
We analyzed the Top 10 failing component types and brands from April’s test results. Notably:
Embedded microcontrollers had the highest failure rate, followed by:
- Aluminum electrolytic capacitors
- Converters (such as voltage and signal converters)
From a brand perspective, the highest failure rates were observed in:
- Avago Technologies
- IXYS
- Mini-Circuits
All three are relatively smaller brands compared to industry giants like TI or ADI. However, it is important to note that these rankings are based solely on April’s data, and reflect a ratio between failure count and testing volume, not a judgment on the brand’s overall quality.
New Demands, Old Fundamentals
April’s results show a continued shift in what manufacturers and buyers expect from quality assurance providers:
- More logistics and handling support
- Increased focus on functional performance
- Continued vigilance in verifying components from both leading and lesser-known brands
