SolderꢀProcessꢀRecommendations: RoHS compliant, lead free. See solder profile on page 3.
In-lineꢀreflow:
Refer to recommended reflow pre-heat and reflow temperatures on page 6. Package material
consist of Ryton R-4 high temperature cover with FR4 substrate. Component solder is Pb free
high temperature eutectic alloy with a melting point of 221°C.|
We recommend using KIC profiler or similar device placing one of the thermocouples on the
device to insure that the internal package temperature does not exceed 221°C.
If for any reason the device needs to be removed from the board, use a temperature controlled
repair station with profile monitoring capabilities. Following a monitored profile will insure the
device is properly pre-heated prior to relow. Refer to IPC 610E for inspection guidelines.

RecommendedꢀCleaningꢀProcess: (If required)
Device is non-hermetic, water resistance with four weep holes, one in each corner to allow
moisture to be removed during the drying cycle. We recommend in-line warm water wash
with air knife and drying capabilities. If cleaner does not have drying capability, then use hot air
circulated oven. Boards should be placed in the oven vertically for good water runoff
Device must be dried properly prior to use!
