Solder Process Recommendations:
In-line reflow:
Per MIL-STD-202G, Method 215J.
RoHS compliant, lead free. See solder profile on page 4.
Refer to recommended reflow pre-heat and reflow temperatures on page 4. 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.
In-line oven profile:
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 reflow. Refer to IPC 610E for inspection guidelines.
Removal of device:
Recommended Cleaning Process: (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!
Note: If saponifier is used make sure the device is rinsed properly to insure all residues are removed. PH of saponifier should
not exceed 10.
Drying Temperature:
Between 85 to 100°C.
Drying Time:
Time will vary depending on the board size.
Caution: Do not submerge the device!
