Mil/Aero LDL 2 A Little History The following slides show what military and aerospace flows were available from Xilinx for many years Feedback from the space industry and recent military satilitte failures indicated the need for more intensive screening for some applications Our currently proposed full-V flow will follow this brief history
3
Mil/Aero LDL 3 Manufacturing Flows: Serving the needs from “Space to Base” R, V, H, SMD C, I, N, M, SMD
4
Mil/Aero LDL 4 Rad Tolerant Most Select M&SMD Grade More Select N-Grade Select Products C&I-Grade All Xilinx Products Controlled environments Plastic packages Supporting the Aerospace and Defense Market Space environment Radiation hardened Harsh environments requiring hermeticity Ceramic packages Wider temperature range required Plastic packages (Mil Temp) (Mil Temp, SMDs) PLUS
5
Mil/Aero LDL 5 Manufacturing Flows “C and I” grade - Commercial or Industrial Temp, Plastic “M” grade - Military Temp, Ceramic “N” grade - Military Temp, Plastic “R” grade (for space) - Radiation tolerant, Military Temp, Plastic, Extended Flow “V” grade (for space) - Radiation tolerant, Military Temp, Ceramic, Similar to Class-V “H” grade (for space) - Radiation Tolerant, Military Temp, non-hermetic ceramic Standard Microcircuit Drawing (SMD) - Military and Radiation Tolerant, DSCC part number
6
Mil/Aero LDL 6 Extended Flows for Space Extended burn-in (up to 240 hours) XRAY DPA PIND for hermetic packages CSAM for plastic packages
7
Mil/Aero LDL 7 Product Grade Comparisons For Critical Supply Chain Issues Full documentation and controlled extended product life cycle

Mil/Aero LDL 9 Where we are going Many changes are coming from what I will call “acquisition reform II”. Xilinx response to customer needs was to work with industry and customer experts and with DSCC to define screening flows that will satisfy future customer needs in the space and military markets. BUT, an issue arose in that technology developed packages to which traditional full class-S/V flows did not seem to apply. The solution was to work with our partners to develop screening flows for these devices which would demonstrate and the ensure equivalent reliability as standard military screening flows provided.
