Recommended Solder Reflow Profile
Suggested IR profile
VI qualification includes aging at various extreme tem-
peratures, 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 in figure 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 eutectic temperature of Sn/Pb
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 J-
types are 100% screened for hermeticity so an aqueous
wash is not an issue.
