SOLDERING of CYLINDER CRYSTALS
Lead wire should be soldered within 5 seconds with the iron having a tip temperature of less than 270°C. Case 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
