Product Reliability

Electrical Performance Tests:

Low Temperature Resistance: 500 hrs at -40±5, then 1 hr natural cooling.
High Temperature Resistance: 500 hrs at +100±5, then 1 hr natural cooling.
Salt Spray Test: 48 hrs in 35±2 salt water (5% concentration), then wash.
Humidity Test: 500 hrs at 60±2 and 90-98% RH, then 1 hr natural cooling.
Temperature Cycling: 100 cycles of 30 min at -40±2 and 30 min at +85±2, then 2 hrs natural cooling.

Mechanical Performance Tests:

Drop Test: 3 drops from 75±5cm onto a wooden board (>3cm thickness), then 1 hr rest.
Vibration Test: 10-55Hz frequency, 1.5mm amplitude, 2 hrs vibration along X, Y, Z axes, then 1 hr rest.
Terminal Bending Strength Test: Body fixed, 45° twist, then slowly restored.
Terminal Strength Test: After mounting on PCB, apply pressure with 0.5mm/s speed, 2mm bending for 5±1 sec.
Soldering Wettability Test: Apply flux (7-10% concentration) for ~5 sec, then dip in 230±5 molten tin for 3 sec.
Sealing Test: Immerse in 85±5 warm water for 5 min (water level ~20cm above crystal).
Soldering Heat Resistance: 3 min in 265±5 tin bath (2.0±0.2mm from tin surface) (2 times); 3±0.5 sec in 350±10 tin bath (2.0±0.2mm from tin surface) (2 times), then 2 hrs natural cooling.

Judgment Criteria:

() Frequency change: ±5ppm, Resistance change: ±20%Ω
() No lead breakage, meets () requirements.
() Solder coverage > 90%.
() No bubbles on crystal surface or emerging from water.
() Product appearance is qualified.
