Solder Ball and Cleanliness Requirements
The open frame (no case or potting) power module will meet the solder ball requirements per J-STD-001B. These
requirements state that solder balls must neither be loose nor violate the power module minimum electrical spacing.
The cleanliness designator of the open frame power module is C00 (per J specification).
Solder, Cleaning, and Drying Considerations
Post solder cleaning is usually the final circuit-board assembly process prior to electrical board testing. The result
of inadequate circuit-board cleaning and drying can affect both the reliability of a power module and the testability
of the finished circuit-board assembly. For guidance on appropriate soldering, cleaning, and drying procedures,
refer to the Board-Mounted Power Modules: Soldering and Cleaning Application Note
(AP97-021EPS).
