Handling Precautions

Although ESD protection circuitry has been designed into the SO-502 proper precautions should be taken when

handling and mounting. VI employs a human body model and a charged-device model (CDM) for ESD

susceptibility testing and design protection evaluation.

Time (s)

VI qualification includes aging at various extreme temperatures, shock and vibration, temperature cycling, and IR

reflow simulation. The conditions a device can withstand are well understood and devices can be subjected to

the profile above. This profile shows a ramp up condition to prevent thermal shock, a preheat period in which the

flux is activated, a ramp up to 183°C which is the reflow temperature of Sn/Pb eutectic, and a gradual cool down.

The time above 183°C should not exceed 60 seconds and the peak temperature should be no more than 220°C

for 10 seconds. The SO-502’s are hermetically sealed so an aqueous wash is not an issue.
