Testing and inspection

In final test after packaging, which machine works with the tester to feed ICs automatically and sort them according to test results?

  1. AProber
  2. BHandler
  3. CStepper
Show answer and explanation

Answer: B. Handler

A handler automatically carries packaged ICs to the tester's measurement section (socket) and, after testing, sorts them into good and bad parts according to the results. Some have temperature control for testing at high or low temperatures. A prober is used for wafer test.
