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.
