Notes:
|
Refer to Table #2 for test method and stress conditions. |
|
Category 1 die size is <.571" x .643"; Category 2 die size is <.764" x .864"; Category 3 die size is >/=.764" x .864". Refer to Section 8.1. |
|
Qualification of a new assembly plant, or, any new package which has not been qualified in the qualified assembly facility. |
|
Package Type - A package with a unique case outline, configuration, material, piece parts and assembly processes. |
|
Applicable to new piece parts or leadframe where the cavity size is larger than the largest cavity size for the same package. |
|
For new mask from same device family, HTOL may or may not be required; ESD, LU, CAP and CHARDATA are required. |
|
In process monitor data may be used to satisfy this requirement; for Qual data, data from Assy lot traveller may be used. |
|
Acceptance criteria is 0/3, however 9 devices are required for ESD design characterization. |
|
A full qualification is for process, assembly site and package. |
|
Electrical rejects can be used as test sample. |
