Solder, Cleaning, and Drying Considerations

Post solder cleaning is usually the final circuit-board assembly process prior to electrical testing. The result of inad-

equate 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).
