When operated at this bias condition with a baseplate temperature of 70°C, the
MTTF is reduced from 4.8E+6 to 1.0E+6 hours

Junction operating temperature will directly affect the device median time to failure
(MTTF). For maximum life, it is recommended that junction temperatures be
maintained at the lowest possible levels.

Recommended Surface Mount Package Assembly
Proper ESD precautions must be followed while handling packages.
Clean the board with acetone. Rinse with alcohol. Allow the circuit to fully dry.
TriQuint recommends using a conductive solder paste for attachment. Follow solder paste and reflow oven
vendors’ recommendations when developing a solder reflow profile. Typical solder reflow profiles are listed
in the table below.
Hand soldering is not recommended. Solder paste can be applied using a stencil printer or dot placement.
The volume of solder paste depends on PCB and component layout and should be well controlled to
ensure consistent mechanical and electrical performance.
Clean the assembly with alcohol.
