Problems solved by technology

[0004] This kind of manpower-based operation is easy to cause mixed materials, and because manual positioning is not easy to be accurate and force is not easy to balance, it often damages integrated circuits or related fixtures, which seriously affects industrial competitiveness.
In addition, the speed of manual execution of this kind of operation is limited. If it is necessary to strive for delivery time, it must be carried out in large quantities at the same time. The space and labor required for this kind of testing operation are extremely considerable, leading to the industry of system-level testing of integrated circuits. Encountered a bottleneck in development

Embodiment Construction

[0052] figure 2 Shown is the basic operating system structure of the present invention for performing a system-level test on an integrated circuit, using machine automation to insert the integrated circuit into a physical board, so as to test that the integrated circuit is plugged into a designated area on a physical board (such as an integrated circuit foot), whether it is applicable to this kind of solid board, this system level test system of the present invention includes:

[0053] A container 24 for accommodating at least one such solid plate as a test solid plate 25;

[0054] A feeder 21, which accommodates at least one such integrated circuit as an integrated circuit to be tested;

[0055] An installer 22 is used to move the integrated circuit to be tested out of the feeder 21 and insert it into the designated area 26 on the test solid board 25. The installer 22 includes a crimping mechanism 23 for the test to be tested. The integrated circuit is plugged into the spe...

Abstract

The system layer test is one automatic, rather than manual, test of integrated circuits inserted in practical circuit board and the integrated circuits may be drawn out from the practical circuit board and classified automatically. The said automatic system test method of integrated circuit in system lever has no demerits similar to those in manual integrated circuit inserting mode, and is reliable, economic and efficiency.

Description

technical field [0001] The present invention relates to a system-level testing (SLT) solution for integrated circuits, using machine automation to plug the integrated circuits into physical boards for system-level testing. It can also use machine automation to complete system-level testing The integrated circuit is extracted from the solid board and sorted out. Background technique [0002] As application requirements become more and more stringent, the results of simulated testing of integrated circuits are no longer completely reliable. Therefore, the solution of system-level testing of integrated circuits is becoming more and more common. The so-called "system level test" is to plug the integrated circuit into the physical board that it actually needs to be used with, and then treat the physical board as a system to test whether the physical board is normal to determine whether the integrated circuit is suitable for use with the physical board. Solid boards are used. Th...
