SOLDERING of CYLINDER CRYSTALS
Lead wire should be soldered within 10seconds with the iron having a tip
temperature of less than 270°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.
In line with our ongoing policy of product evolvement and improvement, the above specification may be subject to change without notice.
