Abstract

See full text

A composite intermediary device using vertical probe for wafer testing, comprising: a printed circuit board, a glass interposer and a vertical probe set; wherein the printed circuit board has printed circuit connected with a measuring apparatus, the glass interposer has multiple contact pads connected with the printed circuit, and then the probes of the vertical probe set are against the contact pads of the glass interposer and the bumps of the device under test. By a fine pitch configuration of the printed circuit and the contact pads of the glass interposer, the present invention achieves the requirements of synchronous and interleaved testing of multiple ICs.
