DATASHEET
Crystal Unit Handling Precautions
1) Mounting Precautions
Structure – Cylinder crystals are hermetically sealed using glass to metal seals (see figs 1 and 2)
Unbending the lead
(1) DO NOT pull the lead excessively if unbending a lead or removing a crystal unit. The excessive force may crack
the glass and reduce the degree of vacuum. This may eventually result in deterioration of the characteristics and
may also break the crystal chip (see Figure 3).
(2) Unbend the lead by pressing on the bent part from both the upper and lower sides while holding the bottom of
lead tightly (see Figure 4).
Bending the lead
(1) Bend the lead so that the lead will remain straight for more than 0.5mm from the case when soldering a crystal
unit after bending. If not, the glass may be cracked (see Figures 5 and 6).
(2) Always leave a length greater than 2.0mm when bending a lead after soldering (see Figure 7)
Soldering directly to the case will reduce the degree of vacuum and may result in deterioration of the characteristics and may break
the crystal chip.
Make the length from the case to the printed circuit board (L) longer than the case diameter (D) so that the lead wire will not be
pulled in case the crystal unit falls over.

DATASHEET
2) Soldering
The soldering position must be at the lead wire more than 1.0mm away from the glass seal. Excessive heating time at high
temperature may result in deterioration of the characteristics and may break the crystal unit. If crystal unit is unavoidably
heated, heat the lead part at 300℃ or lower for 5 seconds or less and please make sure to keep the case below 150℃.
3) Cleaning
Since a small, thin crystal chip is used for tuning fork crystal units and the frequency approximates that of an ultrasonic
cleaner, the crystal chip may break easily. Therefore, DO NOT perform ultrasonic cleaning.
