Mechanical and environmental performance:

• free fall (impact)
  It fell freely from a height of 75cm to a 30mm thick hardwood board and fell three times, which requires technical specifications.
•  sealing: immerse the resonator in alcohol and pressurize it to 5Kg / cm2 for 5 minutes. Remove the insulation resistance> 500 ohm (DC100V) from the test pin to the pedestal.
• Solderability: from the end of the pin to the bottom of 2 ~ 2.5mm, put it in a solder bath of 235 degrees Celsius ± 5 degrees Celsius for 2 ± 0.5 seconds, and the solder surface of tin is> 90%. Complies with technical specifications.
•  Vibration resistance: Vibration frequency is 10 ~ 55Hz and the amplitude is 1.5mm. After each vibration in the X, Y and Z directions for 2 hours, the test is performed. It meets technical specifications and there is no mechanical damage.
