Testing and inspection

What is it called to classify products by performance, such as operating speed and power consumption, based on test results?

  1. ADicing
  2. BBinning (sorting by performance)
  3. CMolding
Show answer and explanation

Answer: B. Binning (sorting by performance)

Even chips of the same design differ in maximum operating frequency and power consumption because of manufacturing variation. Binning sorts products into performance grades according to test results and ships them as different products. CPU frequency grades are an example.
