  • Publication number: 20070296419
    Abstract: Two electronic device holding portions 19 are formed on an insert to be attached to a test tray TST of an electronic device handling apparatus 1, and the two electronic device holding portions 19 are arranged at positions sandwiching a standard hole 20a used as a positional standard when aligning. When using an insert having a plurality of electronic device holding portions 19, the number of IC devices 2 to be held per a unit area on the test tray TST increases and the throughput improves. Also, when arranging the two electronic device holding portions 19 at positions sandwiching the standard hole 20a, both of the electronic device holding portions 19 can be close to the standard hole 20a, so that positional deviation of the IC devices 2 caused by thermal expansion or thermal contraction of the insert 16 can be suppressed and arising of contact mistakes caused by positional deviation is suppressed.
