Accessories
GEN3 offers custom Test Racks as accessories to the AutoSIR2+ & CAF2+.
Our customisable test racks are designed to facilitate and streamline the SIR & CAF testing process. These test racks are engineered to accommodate multiple printed circuit boards (PCBs) or electronic assemblies for simultaneous testing, making the process more efficient and cost-effective. We can design our test racks around ANY test coupon or assembly and can work with you to design your own coupons for your own manufacturing requirements.
Our test rack can offer you:
- Flexibility: The test racks are designed to be highly flexible, allowing for easy customisation to meet the specific needs of different PCB sizes, shapes, and configurations. This adaptability ensures compatibility with a wide range of electronic components and assemblies.
- Multiple Testing Ports: Our racks typically have multiple testing ports, enabling parallel testing of several PCBs/ simultaneously. This feature significantly increases testing throughput, reducing the time required for SIR testing.
- Rain Guard: All of our racks come with a rain guard in case the environmental chamber has an issue where 'rain' occurs. The rain guard protects your assemblies from direct droplets.
- Precise Test Point Access: Our test racks are designed to ensure precise and reliable contact with the PCB's test points. Proper contact is critical for obtaining accurate SIR test results.
- User-Friendly: Our test racks are designed to simplify the setup and operation for SIR/CAF testing, making them accessible to operators with varying levels of expertise.

FAQs
CAF testing is a critical process for assessing the reliability of printed circuit boards (PCBs). It identifies the risk of conductive filaments forming within the PCB substrate, which can lead to short circuits and product failure. Testing helps prevent costly failures and ensures product longevity.
The AutoCAF2+ is capable of testing to all existing test specifications, including IPC, IEC, JNC, and other user-defined specifications.
Yes, the AutoCAF2+ features advanced multibias capabilities, allowing testing with up to three different bias voltages in a single run for exceptional flexibility.
During testing, the system continuously monitors resistance, current, applied voltage, temperature, and humidity on all selected channels.
The adaptable and flexible software operates with Windows 7 onwards.
Yes, GEN3 Systems offers customizable test racks designed to facilitate and streamline the CAF testing process. These racks can accommodate multiple PCBs for simultaneous testing and can be designed around any test coupon or assembly.
The AutoCAF2+ helps improve product reliability by identifying potential CAF failures early in the development process. It can test up to 256 channels simultaneously with voltages up to 1250V, allowing for comprehensive testing of modern high-density PCBs. By detecting CAF issues before they become field failures, manufacturers can avoid costly recalls, repairs, and damage to their reputation. The system's ability to test multiple PCBs in parallel also reduces overall testing time and costs.
The AutoCAF2+ offers unparalleled flexibility and performance. Its advanced multibias feature allows testing with up to three different bias voltages in a single run, providing exceptional versatility. With measurement capabilities from 10^6 Ω to 10^14 Ω and the ability to take readings from all 256 channels in less than 30 seconds, it offers both precision and speed. The system is also future-proofed with adaptable software compatible with Windows 7 and newer, ensuring long-term value for your investment.
