Notes:
1. Actel offers the extended flow for customers that require additional screening beyond the requirements of MIL-STD-883, Class B.
Actel is compliant to the requirements of MIL-STD-883, Paragraph 1.2.1, and MIL-I-38535, Appendix A. Actel is offering this
extended flow incorporating the majority of the screening procedures as outlined in Method 5004 of MIL-STD-883 Class S. The
exceptions to Method 5004 are shown in notes 2 and 3 below.
2. Wafer lot acceptance is performed to Method 5007; however, the step coverage requirement as specified in Method 2018 must be
waived.
3. Method 5004 requires a 100 percent, non-destructive bond pull (Method 2023). Actel substitutes a destructive bond pull (Method
2011), Condition D on a sample basis only.
