13 Shipment, Handling, and Storage
13.1 Shipment
The LS Research APEX Modules are delivered in single piece, or 50 piece cartons in individual
anti-static bags.
13.2 Handling
The APEX/APEX LT Module is designed and packaged to be processed in an automated
assembly line.
! Warning - The Modules contain highly sensitive electronic circuitry. Handling without proper
ESD protection may destroy or damage the module permanently.
! Warning - According to JEDEC ISP, the APEX Modules are moisture sensitive devices.
Appropriate handling instructions and precautions are summarized in Section 2.1. Read
carefully to prevent permanent damages due to moisture intake.
13.3 Storage
Storage/Shelf life in sealed bags is 12 months at <40ºC and <90% relative humidity.
14 Processing
14.1 Moisture Preconditioning
Both substrate and some components can absorb moisture. JEDEC specification J-STD-020 must
be observed to prevent the delamination and cracking associated with the “popcorn” effect”
during solder reflow, (the popcorn effect can be described as miniature explosions of water
vapor that has been trapped in gaps).
Baking before processing is required if module is exposed to excessive humidity.
Recommended baking procedure:
Oven: Convection flow oven.
Duration: 48 hours
Temperature: 125ºC
Humidity: Below 5%.
After conditioning (baking) modules should be processed within the specified floor life:
for products with
moisture sensitivity level 4, the floor life is three days, or precisely 72 hours,
assuming factory temperature and humidity conditions of <30ºC, and <60% relative
humidity.
If they cannot be processed within this time period, place the modules with desiccant and a
moisture indicator into a humidity proof bag and use a vacuum hot barrier sealing machine
for sealing
Other Storage options such as a nitrogen cabinet or dry box are also possible.
Note: A repeated baking process will reduce the wetting effectiveness of the land contacts.
