Reliability Analysis • Major component chosen for analysis: • Switching Regulators (LM2679SD-5.0, LM2679SD-3.3) • Hottest running components • Microcontroller (MCS12A64CFUE) • Most complex component • Quad 2 to 1 Multiplexer (SN74CBT3257) • Failure leads to crashing • Linear Amplifiers for thermopiles (AD8626) • Failure would cause unstable flight, possibly crashing
FMECA Criticality Levels • High – Could cause personal injury • Medium – Inhibits ability to fly autonomously • Low – Inhibits ability to take photos or other inconveniences
