Q.8 Fault Isolation Fault Isolation is pivotal to the success of product defect learning. It pinpoints the locations of potential defects before physical failure analysis to reveal the root cause. In general, fault isolation approaches can be classified as software and hardware based techniques. i) Name 2 software based methods [2 mark] Hardware fault isolation is also commonly known as electrical failure analysis. ii) Name 2 non-laser based electrical fault isolation techniques. [2 mark] iii) What are the advantages and disadvantages of performing frontside fault isolation in Fig. Q8 (a) and (b). [4 marks) Flip Chip Die 30 Flip-chip substrate (a) (b) Fig. Q8 iv) Describe two qualitative observations that can be derived from the experimental plot below Fig. 08 (c).
