Cleaning system and a package carrier for a semiconductor package

摘要

A semiconductor package holder includes two plates, and each plate defining a through-hole. Each of the plates has a set of first members along a periphery of the through-hole and extending into the through-hole. The first members of one of the plates are positioned to overlie the first members of the other of the plates. One of the at least two plates further has a set of second members along a periphery of the through-hole and extending into the through-hole.
