202102010F01 : Incorporation of Tape Holder for TSSOP48/TSSOP56 Assembly
Two changes will be made: 1) NXP will implement a leadframe tape holder to provide long lead stability at wire bond. 2) Realign MSL rating to MSL3 to be consistent with other package types. (which results in a change from non-drybagged to a dry bag ship format)

Reason of Change
1) Implement a 'tape holder' in the assembly process where the leadframe is affixed to the platen in the wire-bond process. This is being done to eliminate vibration during wire bonding thereby improving wire bond robustness. Its key to note that the current assembly methodology is robust as Millions of the TSSOP48/56 package have been produced without the tape and there has been only 1 return where a broken ball neck was observed. This implementation is in-line with on going continuous improvement and in support of customer delivery needs. The 'to-be' implemented tape solution has been successfully employed on several package types within NXP. 2) To further improve package robustness ratings on those TSSOP48/56 products with rating MSL1 will be changed to MSL3 to be internally consistent within the package family. This change virtually eliminates package delamination after assembly reflow. As there will be a reclassification from MSL1 to MSL3 the associated orderable 12NC will need to also be changed. The Final PCN will contain the updated 12NC information.
