Table 4 General CharacteristicsSoldering Recommendations
Recommended Reflow Profile for Lead Free Solder
Note: The quality of solder joints on the castellations (‘half vias’) where they contact the
host board should meet the appropriate IPC Specification. See IPC-A-610-D Acceptability
of Electronic Assemblies, section 8.2.4 Castellated Terminations.”
Figure 2 Reflow Profile
Repeating Reflow Soldering
Only a single reflow soldering process is encouraged for host boards.
Cleaning
In general, cleaning the populated modules is
strongly discouraged. Residuals under the
module cannot be easily removed with any
cleaning process.
Cleaning with water can lead to capillary
effects where water is absorbed into the gap
between the host board and the module.
The combination of soldering flux residuals
and encapsulated water could lead to short
circuits between neighboring pads. Water
could also damage any stickers or labels.
Cleaning with alcohol or a similar organic
solvent will likely flood soldering flux
residuals into the RF shield, which is not
accessible for post-washing inspection. The
solvent could also damage any stickers or
labels.
Ultrasonic cleaning could damage the
module permanently.
OPTICAL INSPECTION
After soldering the Module to the host board,
consider optical inspection to check the
following:
Proper alignment and centering of the
module over the pads.
Proper solder joints on all pads.
Excessive solder or contacts to neighboring
pads, or vias.
REWORK
The module can be unsoldered from the host
board if the Moisture Sensitivity Level (MSL)
requirements are met as described in this
datasheet.
Never attempt a rework on the module
itself, e.g. replacing individual
components. Such actions will
terminate warranty coverage.
HANDLING AND STORAGE
Handling
The W1001 modules contain a highly sensitive
electronic circuitry. Handling without proper
ESD protection may destroy or damage the
module permanently. ESD protection may
destroy or damage the module permanently.
Moisture Sensitivity Level (MSL)
Per J-STD-020, devices rated as MSL 4 and
not stored in a sealed bag with desiccant pack
should be baked prior to use.
After opening packaging, devices that will be
subjected to reflow must be mounted within 72
hours of factory conditions (<30°C and 60%
RH) or stored at <10% RH.
Bake devices for 48 hours at 125°C.
Storage
Please use this product within 6 months after
receipt. Any product used after 6 months of
receipt needs to have solderability confirmed
before use.
The product shall be stored without opening the
packing under the ambient temperature from 5 to
35deg.C and humidity from 20 to 70%RH.
(Packing materials, in particular, may be
deformed at the temperatures above this range.)
Do not store in salty air or in an environment
with a high concentration of corrosive gas, such
as Cl2, H2S, NH3, SO2, or NOX.
Do not store in direct sunlight.
The product should not be subject to excessive
mechanical shock.
