Lab Companion CPO High & Low Temperature Aging Chamber – Ultimate Solution for Silicon Photonics Long-Term Reliability Validation

1. Industry Requirements & Value of CPO Silicon Photonics Aging Test

Silicon photonics (SiPh) technology integrates optical waveguides, high-speed modulators, and photodetectors on a single silicon chip. Featuring high integration, low power consumption, and excellent mass-production compatibility, it has become the core technical pillar for Co-packaged Optics (CPO). As CPO technology accelerates from R&D to large-scale commercialization, long-term operational reliability has become a critical evaluation indicator for global SiPh/CPO components.

High and low temperature aging testing is a mandatory and core procedure to verify the long-term reliability of CPO devices. By operating components continuously under extreme high and low temperature environments, the test accelerates material aging and exposes potential defects in materials, packaging and manufacturing processes. It effectively screens early failure samples and ensures consistent quality and service life of mass-produced products, serving as an indispensable quality control step for global CPO industrial production.

SiPh/CPO aging tests impose extremely strict and specialized requirements on test equipment:

• Long-duration continuous operation: Aging tests typically run for hundreds to thousands of hours. Zero downtime is required throughout the entire test cycle to avoid invalid data and sample loss.

• Precise & uniform temperature control: Tiny temperature fluctuations or chamber temperature deviations will cause inconsistent aging effects and inaccurate test results.

• High-volume batch testing capability: Mass production quality screening demands large-capacity chambers to support batch sample aging and improve testing efficiency.

• Safe powered aging support: Dynamic powered aging requires professional safety protection and reserved test interfaces.

Lab Companion, a professional environmental test equipment brand originating from China’s advanced manufacturing base, focuses on high-reliability test solutions for the global optoelectronic and semiconductor industries. Targeting the exclusive pain points of CPO silicon photonics aging tests, we have developed a dedicated high and low temperature aging chamber series. With ultra-stable long-term operation, high-precision temperature control, and comprehensive safety protection, our equipment provides standardized and reliable reliability verification solutions for global CPO manufacturers.

2.2 High-Precision Temperature Control, Ensuring Consistent Batch Aging Results

CPO silicon photonic devices are highly sensitive to ambient temperature. Consistent temperature stability and uniformity are critical to ensure repeatable and credible test data. Lab Companion achieves industry-leading temperature control accuracy through PID algorithm optimization and CFD airflow simulation design.

The equipment achieves temperature fluctuation of ±0.5℃ and temperature uniformity ≤±2℃, ensuring a consistent temperature field in the entire chamber and equivalent aging status for all samples. The adjustable-speed high-efficiency centrifugal fan realizes uniform airflow distribution without dead angles, avoiding airflow impact on precision optical components while maintaining temperature uniformity.

Covering a wide temperature range of -70℃ to +150℃, the chamber fully supports mainstream international CPO aging conditions, including -40℃ low-temperature aging, 85℃ standard aging, and 125℃ high-temperature accelerated aging, covering all R&D and mass production test scenarios.
