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.
