Case temperature should not exceed 150°C With regard to wave soldering it is recommended that the process is carried out with the crystal unit set upright on the circuit board. Should the process be carried out with the crystal unit on its side then steps must be taken to prevent heat transfer through the can. Should the whole crystal unit be heated (in a re-flow oven for example) it will result in amarked deterioration of the performance or even failure to oscillate. This is due to the internal construction of the crystal unit which involves the use of solder.
