If baking is required, devices may be baked:

a) 192 hours at 40℃,and <5% RH(dry air/nitrogen) or

b) 96 hours at 60℃,and <5% RH for all device containers

c) 24 hours at 125 °C

Soldering Condition

a) Pb-free solder temperature profile

b) Reflow soldering should not be done more than two times.

c) When soldering, do not put stress on the unit during heating.
