DEVICE FOR ASSEMBLING PHOTOELECTRIC ELEMENT ON SUBSTRATE

摘要

A device includes a vacuum nozzle, a driver, a measuring unit, and a controller. The nozzle lifts and holds a photoelectric element having a first electrode and a second electrode. The driver drives the nozzle to press the photoelectric element onto a substrate having a soldering pad and a contact, such that the second electrode is electrically connected to the soldering pad via a layer of conductive glue.;The measuring unit measures a resistance across the first electrode and the contact of the substrate when the photoelectric element is pressed onto the substrate. The controller controls the driver to drive the nozzle to keep pressing the photoelectric element harder and harder into the substrate until the resistance stops decreasing, that is, when the layer of conductive glue is at its thinnest.
