Abracon recommends a land pattern with a minimum pad size of 1.3mm x 1.3mm and a non-solder mask defined (NSMD) pad shape to ensure reliable soldering and minimize thermal resistance.
To minimize high frequency noise and EMI, use a low-ESR capacitor, keep the crystal as close to the microcontroller as possible, and use a ground plane to shield the crystal and its traces. Additionally, consider using a ferrite bead or common-mode choke to filter out high-frequency noise.
The AIUR-06-680K is rated for operation from -40°C to +85°C, but it's recommended to derate the frequency tolerance and stability over the full temperature range to ensure reliable operation.
While the AIUR-06-680K is designed to be rugged, it's still a sensitive component. In high-vibration environments, consider using a vibration-dampening material, such as a silicone adhesive, to secure the crystal to the PCB. Additionally, ensure the PCB is properly secured to the device or chassis to minimize mechanical stress.
To troubleshoot issues with the AIUR-06-680K, start by verifying the crystal's oscillation frequency using an oscilloscope or frequency counter. Check for proper power supply decoupling, ensure the crystal is properly soldered, and verify the microcontroller's clock configuration. If issues persist, consult Abracon's application notes and technical support resources.
