(°C) f-fo fo = k(T-To) 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. The crystals may be wave soldered, taking proper precautions to avoid desoldering the leads. A slow machine rate or too high a pre-heat temperature or solder bath temperature can damage the crystals. Lead to package solder interface temperature should not exceed 175°C, and glass lid to package seal rim temperature should not exceed 210°C. Should the seal rim temperature exceed these limits the package may lose its hermeticity. Loss of hermeticity results in a decrease of frequency and increase in motional resistance.
