Week 24 Summary                                                                        

Yields went from divergent to convergent in Week 24. Electrical Testing yields collapsed again after spiking in Week 23 while Inspection yields staged a recovery.

Electrical Testing yields continued their three-week rollercoaster ride by landing at 67% in Week 24 after reaching 94% in Week 23 after plummeting to 64% in Week 22. A far cry from consistently falling into the 70-75% range for nearly two months.

There are six new devices added to the substandard parts list as result, one of which has a 100% failure rate and another nearly there at 98%.

Inspection yields climbed back to 70% in Week 24 after having plunged to just 56% buyer acceptance in Week 23.
