PROCESSING (Continued)
Hand Soldering
Hand soldering is possible. When using a soldering iron, follow IPC recommendations (reference document IPC-7711).
Rework
The module can be unsoldered from the host board. Use of a hot air rework tool should be programmable and the solder
joint and module should not exceed the maximum peak reow temperature of 250 ºC.
Caution
If temperature ramps exceed the reow temperature prole, module and component damage may occur due to thermal
shock. Avoid overheating.
Warning
Never attempt a rework on the module itself, (e.g., replacing individual components). Such actions will terminate
warranty coverage.
Additional Grounding
Attempts to improve module or system grounding by soldering braids, wires or cables onto the module RF shield cover is
done at the customer's own risk. The numerous ground pins at the module perimeter should be sufcient for optimum
immunity to external RF interference.
QUALITY
CEL modules offer the highest quality at competitive prices. Our modules are manufactured in compliance with the IPC-A-610
specication, Class II. Our modules go through JESD22 qualication processes which includes high temperature operating life
tests, mechanical shock, temperature cycling, humidity and reow testing. CEL modules are 100% factory tested for RF and
DC performance. In addition, every production lot is sample tested for compliance with CEL’s high quality and performance
standards.
CEL builds quality into our products giving our customers the condence when integrating our products into their systems.
SHIPMENT, HANDLING AND STORAGE
Shipment
The modules are delivered in trays of 50.
Handling
The modules are 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
The modules are moisture-sensitive devices. Appropriate handling instructions and precautions are summarized in J-STD-033.
Read carefully to prevent permanent damage due to moisture intake.
Moisture Sensitivity Level (MSL)
MSL 3, per J-STD-033.
Storage
Storage/shelf life in sealed bags is 12 months at <40°C and <90% relative humidity.
