Soldering

Please use our recommended reflow temperature profile for reflow soldering. Further please avoid temperature higher than recommended conditions as our product may deteriorate.

Cleaning

Please avoid ultrasonic cleaning with the unit and unit mounted on the printed circuit board, as the tuning fork crystal may deteriorate because of resonant frequency nearby general ultrasonic.

Product Storage

Please store the product in an environment where the temperature is 5 to 35℃, humidity is 45 to 85%, and atmospheric pressure is 86 to 106 kPa, avoiding direct sunlight. Solderability may deteriorate if the product is stored under high temperature and high humidity.

Electrostatic

Please take countermeasure for electrostatics as it may cause product deterioration or failure if excessive electrostatics apply to crystal product.

Other Notes

Please note that excessive impact may be applied to the product when the board is broken after mounting, and the product may deteriorate. Please avoid processing such as ultrasonic welding to the mounting board, as it may cause product deterioration or failure because excessive force is applied to the inside of the crystal product.
