Abstract

A first spring 54 is provided between a support member 51 driven in the Z-axis direction and a heat block 53 , and biases the support member 51 and the heat block 53 in the direction of separating them from each other. A second spring 57 is provided between a first pusher 55 for pressing a die 81 of an IC device 8 and a second pusher 56 for pressing a substrate 82 of the IC device 8 , and biases the first pusher 55 and the second pusher 56 in the direction of separating them from each other. According to an electronic device handling apparatus having the above configuration, it is possible to respond to changes of kinds of electronic devices, improve surface conformance and uniformly press an electronic device with an accurate load.

Claims (16)

1. A pressing member for pressing terminals of an electronic device to be tested against a contact portion of a test head in an electronic device handling apparatus, comprising:

a first pressing member for pressing a first part of the electronic device by being pressed by a body side-first pressing member made of an inelastic body and elastically biased in the pressing direction,

wherein said body side-first pressing member has a temperature control function for controlling a temperature of said first pressing member,

a second pressing member for pressing a second part of the electronic device by being pressed by a body side-second pressing member made of an inelastic body,

a convex portion protruding to the second pressing member side formed on an upper portion of the first pressing member;

another convex portion protruding to the first pressing member side formed on a lower portion of the second pressing member; and

an elastic body provided between the convex portion of the first pressing member and the another convex portion of the second pressing member, the elastic body biasing the first pressing member and the second pressing member to the direction of separating them from each other,

wherein said first pressing member and said second pressing member are elastically connected in the pressing/receding direction, wherein the first pressing member presses a die of an electronic device to be tested, and the second pressing member presses a substrate of the electronic device to be tested.

2. A pressing member for pressing terminals of an electronic device to be tested against a contact portion of a test head in an electronic device handling apparatus, comprising:

a first pressing member for pressing a first part of the electronic device by being pressed by a body side-first pressing member made of an inelastic body and elastically biased in the pressing direction,

a second pressing member for pressing a second part of the electronic device by being pressed by a body side-second pressing member made of an inelastic body,

a convex portion protruding to the second pressing member side formed on an upper portion of the first pressing member;

another convex portion protruding to the first pressing member side formed on a lower portion of the second pressing member; and

an elastic body provided between the convex portion of the first pressing member and the another convex portion of the second pressing member, the elastic body biasing the first pressing member and the second pressing member to the direction of separating them from each other, wherein

said first pressing member and said second pressing member are elastically connected in the pressing/receding direction, wherein the first pressing member presses a die of an electronic device to be tested, and the second pressing member presses a substrate of the electronic device to be tested, and

said pressing members are attached in a removable way to an electronic device handling apparatus body side provided with said body side-first pressing member and said body side -second pressing member.
