Week 9 Quality Report

Physical Inspection - 76% Accepted

Electrical Testing - 61% Passed

In the 9th week of 2011, White Horse facilitated USD93,855.00 in reliable component purchases.

Week 9 saw more lower overall quality levels, with decreases in both mechanical/visual and electrical test results, reflecting the continued trend in substandard discrete devices.
