Description

Burn-in test circuit board module

A circuit board module, especially an aging test circuit board module.

Electronic components, including semiconductor components, integrated circuit components, etc., must undergo aging tests before leaving the factory to pick out the components that have early failures from all finished products, and improve the stability and reliability of the final product. Generally speaking, the aging test system mainly puts the component under test in an aging test machine that generates a high-temperature environment. The aging test machine also provides a test signal to the component under test, so that the component under test is in a harsh environment. Accept the test signal in the environment for a period of time. During this aging time, the components under test that have defects or are prone to early failure will fail, and the manufacturer can further select the defective or faulty products through functional testing. Furthermore, in order to test multiple DUTs at the same time to improve the overall test and output efficiency, please refer to FIG. 10, a large printed circuit board 70 is provided with multiple DUTs 71 connected in parallel, and the The large printed circuit board 70 is sent to the burn-in test machine to perform burn-in tests on multiple components under test 71 at the same time to improve the test efficiency. The large printed circuit board has an electrical connection end. A plurality of edge connectors 72 (Edge connectors), or commonly known as "golden fingers", are provided on the electrical connection end to be inserted into the corresponding slot in the burn-in test machine and communicate with the burn-in test machine. The stage forms an electrical connection, so that the burn-in testing machine stage can output side test signals to a plurality of components under test 71 on the large printed circuit board 70 through the side joint.

However, with the development of technology, the existing components under test have become more complex, and the number of input and output pins on a single component under test has also increased. The large printed circuit board 70 has to set circuit leads corresponding to the total number of input and output pins, and The corresponding circuit board wiring concerns are also more complicated. The circuit layers on the large-scale printed circuit board 70 must be correspondingly increased to properly accommodate all the circuits derived from each component under test. When the circuit layer of the large printed circuit board 70 increases, its thickness also increases, and the thickness of the side joint 72 of the large printed circuit board 70 also increases correspondingly. However, the slot size of the burn-in test machine is fixed, that is, the thickness of the side connector 72 that can be inserted into the slot is also fixed, so it cannot accommodate large printed circuits whose thickness exceeds its inherent specifications due to the increase in the number of circuit layers.板70. In other words, the existing burn-in test machine cannot adapt to the thickness required for the large-scale printed circuit board 70 used for testing high-complexity components under test, and the replacement of the burn-in test machine will incur excessively high costs. Therefore, the aging test module in the prior art must be further improved.

In view of the fact that the existing burn-in test system is difficult to apply to the components under test with high complexity, this invention provides a burn-in test circuit board module, which includes a first circuit board, a second circuit board, an adapter module, and a A fixed connection component, the first circuit board includes a first circuit layer, and has a plurality of side connectors and a plurality of first adapters, and each side connector is electrically connected to each of the first adapters through the first circuit layer .

An adapter module is electrically connected to each of the first adapter and each of the second adapters, so that each of the first adapters of the first circuit board is electrically connected to the second circuit board through the adapter module Each of the second adapter. The fixing component is fixed to the first circuit board and the second circuit board, so that the first circuit board and the second circuit board are fixed to each other through the fixing component.

The first circuit board is a printed circuit board whose thickness conforms to the slot of the burn-in test machine. The side connector is a circuit board external connector generally called "golden finger" for inserting into the slot of the burn-in test machine. Receive test signals; each of the component sockets of the second circuit board is used to set a plurality of components to be tested, and the second circuit board is based on the number of input and output pins of the component to be tested and the component to be tested The quantity and other test and wiring design requirements set the required second circuit layer so that each of the component sockets receives the test signal through the transfer module, the first circuit layer of the first circuit board and each of the side connectors. Since the first circuit board is only for transmitting test signals, there is no need to install the components to be tested, the wiring restrictions are few and the rules are simple, and the circuit leads can be arranged with fewer first circuit layers to electrically connect each side connector and each The first adapter seat, therefore, the thickness of the first circuit board can be thinner than that of the second circuit board, and can meet the slot specifications of the burn-in test machine.

In this way, the first circuit board and the second circuit board are electrically connected by the transfer module to form the required electrical connection, so that the second circuit layer of the second circuit board can be protected from the aging tester. The slot specification limit of the platform meets the connection requirements of the components under test with high complexity; and the first circuit board sets the connection line on the first line layer according to the slot specification of the burn-in test machine, and achieves the transmission test signal purpose. The burn-in test circuit board module can be applied to components to be tested with high complexity and conform to the specifications of the existing burn-in test machine, so as to solve the problem that the existing burn-in test system does not meet the needs of product development.
