Week 5 Summary                                                                        

 

The roll continued! Another week of improving yields in Electrical Testing and Inspection were seen in Week 5.

 

Inspection yields set the pace by climbing another 6 points to land at 81% in Week 5 and Electrical Testing soldiered on to gain another three points and land on the same spot, matching that 81% in Week 5 after posting 78% in Week 4.

 

Not surprisingly, there are fewer new additions to the Substandard Parts List with only two entries.
