World's smallest size Crystal Resonator with a dedicated temperature sensor
DAISHINKU CORP. has been producing crystal resonators with a dedicated temperature sensor in sizes of 2520 (2.5 x 2.0 mm) and 2016 (2.0 x 1.6 mm). We now have successfully developed a further downsized model at a size of 1612 (1.6 x 1.2 mm), which represents one of the smallest in the world.
As the chipset uses the temperature information provided by a dedicated temperature sensor in a crystal resonator to control the temperature, the crystal specifications must be even more precise than those for general-use resonators. For example, the AT-cut crystal temperature coefficient and inflection point temperature vary according to the crystal's size and shape. As the crystal size becomes smaller, the more difficult it becomes to control quality uniformity. Thus, even higher accuracy in crystal production processes is required.
To address this issue, we have established a crystal design that is less susceptible to the variations caused by processing, ensuring the design margin of this smaller model is equal to or better than conventional models. We have also realized even greater processing accuracy utilizing existing production facilities to achieve continuous and uniform quality. The package is optimized by adopting a low-profile temperature sensor (NTC thermistor) to realize both downsizing and a low-profile, while also securing reliability equal to existing 2520 and 2016 crystal resonators with dedicated temperature sensors.

World's thinnest Tuning Fork Crystal Resonator in 1610 size*, the DST1610AL
DAISHINKU CORP. developed world's thinnest(hight:0.35mm max) tuning fork crystal resonator in 1610 size*.
Generally, when downsized, a tuning fork crystal oscillator noticeably degrades in electrical characteristics since its series resistance increases. Moreover, in element mounting, the conventional use of electrically conductive adhesive is subject to design limitations if the aim is to make the product smaller and thinner. To solve these problems, new element design provides a necessary distance between oscillating and base sections. The results are reduced oscillation leaks to the base section and reduced increases in series resistance. In addition, the FCB method used to mount the element on the package provides stability in mounting-position accuracy, an important factor in making the product low profile.
