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 temperature should 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.
