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...
