Abstract

The embodiment of the invention relates to the technical field of semiconductor chip quality reliability, and especially relates to a burn-in board which is simple to operate and highly universal. According to the embodiment of the invention, a first pin and a second pin on a first pin header are communicated, and the first pin or the second pin is grounded; a first pin on a second pin header is communicated with a port S, and a second pin is communicated with a port G; a first pin, a second pin and a third pin on a third pin header are respectively communicated with the port G, a port D and the port S; and a first pin, a second pin and a third pin on a fourth pin header are communicated with VCC. Any of the port S, the port D and the port G can be grounded or connected to a power source by plugging a short-circuit cap onto the pin headers, so that a variety of experiments can be conducted by changing the plugging of the short-circuit cap, and the universality of the burn-in board is further improved.

Description

Technical field [0001] The invention relates to the technical field of semiconductor chip quality reliability, in particular to an aging board. Background technique [0002] With the continuous development of semiconductor technology, the application fields of chips have begun to continue to extend, and the reliability requirements for chips have become higher and higher. In order to ensure the reliability of the chip, the chip is usually burn-in test (Burn-inTest), that is, after the chip is manufactured, the chip is often mounted on a burn-in board. At high temperatures, it is generally 150 for silicon devices. ℃ and above, make the chip expose the defects in the device as soon as possible, so as to detect defective devices. [0003] At present, the general burn-in board in the industry needs to analyze the failure mode of the chip by plugging and unplugging accessories (jumpers, resistors) on the burn-in board. In this sample method: the plugging and unplugging process of acce...
