Technical Specifications

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.
