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.
