Abstract
A package tester includes an inlet station for arranging a test board in which package sockets mounting packages are disposed in one or plural lines for performing package test by flowing an electric current through the package and transmitting signals to the package, the package being composed of parts including electric parts or electronic parts and being sequentially formed on a package tape, an inlet pusher for pushing the test board mounting the packages by a width of the test board in a feeding direction of the test board from the inlet station to the package socket, a conveyor for receiving the test board sequentially pushed out of the inlet station by the inlet pusher and conveying the received test board to a testing area, a contact device opposed to the conveyor and capable of being electrically connected to the test board arranged on the conveyor, an outlet station receiving the test board sequentially pushed out of the conveyor by sequentially pushing-out of the test board by means of the inlet pusher, and a reaction urging device for allowing the test board to be pushed out while supporting the test board pushed out to the outlet station with force weaker than pushing out force in the inlet pusher.
