PACKAGE HANDLING

The CX crystal is hermetically sealed in a ceramic package. Normal

handling and soldering precautions for small, low thermal mass parts

are adequate when installing or testing CX crystals. CX crystals may

be wave soldered with proper precaution taken to avoid desoldering

the leads. A slow machine rate or too high a pre-heat temperature or

solder bath temperature may damage the crystals. Lead to package

solder interface temperature should not exceed 175°C, glass lid

to package seal rim temperature should not exceed 210°C. If

the seal rim reaches temperatures above the maximum specified, the

package may lose its hermeticity. Loss of hermeticity results in a

frequency decrease and motional resistance increase.
