example 1

[0150] The closed space S can be notified of overheating through the test processor. Here, the notification method may be to generate an audible alarm or display it visually through the display of the test processor.

example 2

[0152] The work of the test processor can be temporarily stopped. Preferably, after the temperature of the enclosed space S returns to the required temperature range, the stop of the test processor is automatically released.

example 3

[0154] The semiconductor components tested when overheating occurs in the enclosed space S are classified by retest batches.

Abstract

A semiconductor device test system and a test handler are disclosed. A temperature control apparatus is installed to an interface block of a test head and removes heat generated from a testing board. Therefore, the testing of semiconductor devices can be performed with a high degree of reliability.

Description

Technical field [0001] The present invention relates to a semiconductor element testing system and a test processor, and more particularly to a technology in which the interface block of a test head for testing semiconductor elements is provided with a test board for performing testing of semiconductor elements. Background technique [0002] Generally speaking, a semiconductor component test system includes: a test control device; a test head for testing semiconductor components under the control of the test control device; a test processor that provides a plurality of semiconductor components to the test head and makes The semiconductor element can be electrically connected to the test head to allow multiple semiconductor elements to be tested at the same time; the supporting device supports the test head so that the test head can be stably connected to the test processor. This supporting device is also called a "controller" in the technical field of the present invention. [000...
