Crystal Resonator
No Description Contents Requirements
1Lead Strength
Lead Bending
Force of 0.9kg is applied for 10 ±1seconds to each
lead in axial direction.
Firmed the terminal up to 2mm, lead shall be
subjected to withstand against
90º bending its stem. This operation shall be done
toward both direction. No mechanical damage and
the measured values shall
meet electrical parameters.
2 Vibration 10 ~ 500Hz, 0.75mm amplitude, in 3 directions
duration of 2h. Measurement taken after 1 hour.
3 Random Dropping The crystal will be test by natural dropping to 3cm
wooden broad 3 times from high of 75cm.
4 Solder Stability Dipped the terminals no closer than 2mm into the
solder bath at 235°C ±5°C for 2 ±0.5 sec.
At least 95% of the terminal
surface shall be coated by the
solder
5Resistance Solder
Heat
Use a 350°C ±10°C solder iron to touch device under
test at the 2 ~ 2.5mm end part of lead for 10 ±1
seconds. Measurement taken after DUT being left
at room temperature for at least 1hours.
Measured values shall meet
electrical parameters.
6Temperature Cycle
Shock
Temperature cycling from -40°C (30mins) to +85°C
(30mins) was performed 3 times, then placed in a
natural condition for 24 ±2 hours.
7Life Test
(High Temperature)
Placed in a chamber (125°C ±2°C) for 72 hours,
then placed in a natural condition for 24 ±2 hours.
8Life Test
(Low Temperature)
Placed in a chamber (-55°C ±2°C) for 72 hours,
then placed in a natural condition for 24 ±2 hours.
9 Humidity
Placed in a chamber (Humi: 90 ~ 95% RH,
Temp: 40°C ±2°C) for 96 hours, then placed in a
natural condition for 24 ±2 hours.
