Storage Requirement
Moisture Sensitivity
Dimensions
Customer PCB Design
4.2 Storage Requirement
The module must be stored and sealed properly in vacuum package under a
temperature below 40°C and the relative humidity less than 90% in order to ensure
the weldability within 12 months.
4.3 Moisture Sensitivity
The moisture sensitivity is level 3.
After unpacking, the module must be assembled within 168 hours under the
environmental conditions that the temperature is lower than 30°C and the
relative humidity is less than 60%. If the preceding conditions cannot be met, the
module needs to be baked according to the parameters specified in Table 4-1 .

4.5 Customer PCB Design
4.5.1 PCB Surface Finish
The PCB surface finish recommended is Electroless Nickel Immersion Gold (ENIG).
Organic Solderability Preservative (OSP) may also be used, ENIG preferred.
4.5.2 PCB Pad Design
To achieve assembly yields and solder joints of high reliability, it is recommended that
the PCB pad size be designed as follows:

Hardware Guide
4.5.3 Solder Mask
Non Solder Mask Defined (NSMD) is recommended. In addition, the solder mask of
the NSMD pad design is larger than the pad so the reliability of the solder joint can be
improved.
The solder mask must be 100 µm–150 µm larger than the pad, that is, the single side
of the solder mask must be 50 µm–75 µm larger than the pad. The specific size
depends on the processing capability of the PCB manufacturer.
4.5.4 Requirements on PCB Layout
To reduce deformation, a thickness of at least 1.0 mm is recommended.
Other devices must be located more than 3 mm (5 mm recommended) away
from the two parallel sides of the LGA module (rework requirement),and other
sides with 0.6 mm. The minimum distance between the LGA module and the
PCB edge is 0.3 mm.
When the PCB layout is double sided, the LGA module must be placed on the
second side for assembly; so as to avoid module dropped from PCB or
component (located in module) re-melding defects caused by uneven weight.
