Problems solved by technology

[0009] 1. The known integrated circuit test cannot simulate the final use state of the user, so even if it passes the test, problems may occur when the user uses it, such as conflicts with software, etc.
[0010] 2. It is known that all the components placed on the test circuit board are the same type during the test of the known integrated circuit, and the compatibility problem between different components cannot be detected.
[0011] 3. The known test methods still rely on a lot of labor, which limits the production capacity and cost, and also causes the possibility of human error
[0012] 4. The known test method for integrated circuit modules cannot control the operating temperature of the components after the integrated circuit is assembled, that is, at the module stage, so it cannot be simulated for certain states in actual use.
[0013] 5. After the known integrated circuit under test is tested at high temperature, the integrated circuit under test must be moved to other automatic test equipment, and then tested at low temperature. This test method is not very efficient.
[0014] 6. The judgment of known tests is generally based on the final integrated circuit state, and some dynamic errors cannot be detected. For example, in the case of graphics accelerators, image drift (video shaking) and hue variation generated during actual program execution Phenomena such as discoloring display, ghost shallow or white block cannot be detected
Or crashes caused by integrated circuit software execution, etc., cannot be detected by traditional testing methods

Embodiment Construction

[0060] The automatic integrated circuit testing system, device and method of the present invention are performed on a known good computer for testing, and can be used to test any integrated circuit in the testing computer. In the case of a personal computer, such as a central processing unit, a system bus controller, and an input / output bus controller; or an integrated circuit in an interface module, such as a graphics accelerator. Generally, these integrated circuits are configured on a printed circuit board, such as a central processing unit, a system bus controller, and an I / O bus controller are usually configured on a motherboard. Wherein, the CPU is usually electrically connected to the motherboard through a connector such as Socket478, Socket 423, Socket 370, Socket 7, and the like. The memory integrated circuit is configured on a module circuit board, and then electrically connected to the motherboard through a connector, such as DIMM, RIMM, and the like. As for, the s...

Abstract

The testing system includes the testing computer, the automatic plugging and pulling out mechanism, the temp control set and the control set. The testing computer is used for holding and testing the IC to be bested. The automatic plugging and pulling out mechansm puts the IC to be tested on the testing computer and takes the IC tested off from the testing computer. The temp control set controls the temp of the IC to be tested. The control set is connected to the testing computer and the plugging and pulling out mechanism electrically, controlling the operation of the plugging and pulling out mechanism. The testing computer combines the IC to be tested forming an integrated computer. The temp control set controls the temp at preset condition. The control set carriage out the integrated testing.
