Abracon recommends a land pattern with a minimum pad size of 1.3mm x 0.8mm and a non-solder mask defined (NSMD) pad shape to ensure reliable soldering and minimize thermal resistance.
To minimize the impact of vibration and shock, Abracon recommends mounting the crystal on a rigid PCB, using a shock-absorbing material (e.g., silicone) under the crystal, and ensuring the crystal is properly secured to the PCB using a suitable adhesive or mechanical fastening method.
While the datasheet specifies an operating temperature range of -40°C to +85°C, Abracon recommends derating the crystal's frequency tolerance and stability above 70°C to ensure reliable operation.
Abracon recommends using a moisture-resistant coating or conformal coating on the crystal and PCB to prevent moisture ingress and ensure reliable operation in humid or high-moisture environments.
To maintain frequency accuracy and stability, Abracon recommends using a high-quality crystal oscillator circuit design, ensuring proper PCB layout and routing, and storing the crystal in a dry, cool environment when not in use.
