  • recommended mounting: 2. soldering: • pre-heating +130 ° C ~ + 150 ° C for 1 to 3 mintues
  • soldering +230 ° C ~ + 250 ° C for 5 seconds maximum 3. cleaning: • ultrasonic cleaning with organic solvents
  • ultrasonic frequency should not be equal to the resonance frequency of the crystal 4. handling: • handle the crystal carefully, it cannot stand heavy shock 5. testing: • if you test the whole board automatically do not apply pulse to the crystal oscillator circuit, especially high pulse level can break the crystal blank MMTF32 MTF32 Jauch Quartz GmbH • Telephone: (+49) 77 20 / 9 45-0 • Telefax: (+49) 77 20 / 9 45-100 • Internet: www.jauch.de • e-mail: hcj@jauch.de • 08/2002
