ABSTRACT:
The method of sorting semiconductor devices includes the steps of feeding semiconductor devices into a contact mechanism and simultaneously connecting the contact elements of the contact mechanism to the leads of one semiconductor device, measuring the parameters of this semiconductor device while disconnecting the contact elements of the contact mechanism from the leads of another semiconductor device and delivering the latter. The apparatus for sorting semiconductor devices includes a device for loading the semiconductor devices, a contact mechanism underlying the loading device, coupled to the unit for measuring the electric parameters of the semiconductor devices and comprising contact elements mounted for timed motion, a conveying mechanism underlying the contact mechanism, the latter being associated with a drive and having two slots.
