Abstract

A process for using removable Z-axis anisotropically conductive adhesive material (21) which includes water, a matrix resin (23), and conductive spheres (22). The material (21) is suitable for providing temporary contact between electronic devices. In one embodiment, the material (21) is used to temporarily bond a semiconductor wafer (11) to a probe substrate (12) for wafer-level burn-in.
