General Handling Recommendations for the
C4-CQFP Package
The following list provides a few guidelines for package handling:
Handle the electrostatic discharge sensitive (ESD) package with care before, during, and after
processing.
Do not apply any load to exceed 3 Kg after assembly.
Components should not be hot-dip tinned.
The package encapsulation is an acrylated urethane. Use adequate ventilation (local exhaust) for all
elevated temperature processes.

A.1 Package Environmental, Operation, Shipment,
and Storage Requirements
The environmental, operation, shipment, and storage requirements are as follows:
Make sure that the package is suitable for continuous operation under business ofce environments.
— Operating environment: 10
°C to 40 °C, 8% to 80% relative humidity
— Storage environment: 1
°C to 60 °C, up to 80% relative humidity
— Shipping environment: 40
°C to 60 °C, 5% to 100% relative humidity
This component is qualied to meet JEDEC moisture Class 2.
After expiration of shelf life, packages may be baked at 120
°C (+10/–5 °C) for 4 hours minimum
and then be used or repackaged. Shelf life is as specied by JEDEC for moisture Class 2
components.
A.2 Card Assembly Recommendations
This section provides recommendations for card assembly process. Follow these guidelines for card
assembly.
This component is supported for aqueous, IR, convection reow, and vapor phase card assembly
processes.
The temperature of packages should not exceed 220
°C for longer than 5 minutes.
The package entering a cleaning cycle must not be exposed to temperature greater than that
occurring during solder reow or hot air exposure.
It is not recommended to re-attach a package that is removed after card assembly.
