SOLDERING of CYLINDER CRYSTALS
Lead wire should be soldered within 10seconds with the iron having a
tip temperature of less than 270°C. Can must 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.
Please note that all parameters can not necessarily be specified in the same device
