Embodiment Construction
[0040] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.
[0041] On the processor, the chip is usually connected to the socket 1 on the circuit board through pins. There is a first reference position on the chip and a second reference position on the substrate, and only when the first reference position and the second reference position are aligned, the connection position between the chip and the substrate is correct.
[0042] Usually, it is necessary to adjust the above-mentioned first reference position and second reference position by manually aligning or comparing image data with an image acquisition component, so as to determine that the chip is placed correctly.
[0043] However, in the embodiment of the present invention, it is not necessary to consider the position deviation between the first reference position and the second reference positio...

The invention discloses a chip calibration system and method, belonging to the technical field of chip position calibration. A detection system is provided with a detection unit. The chip calibration system comprises a connecting seat, a position detecting device, a processing device and a calibration device, wherein the connecting seat matches pins of a chip, and is connected with the detection unit. The calibration method comprises that the position detecting device determines the circuit state between a first preset position and a second preset position; the processing device reads the circuit state and matches the circuit state with a preset reference state; the processing device sends a control instruction to the calibration device according to a matching result; and according to the control instruction, a switching module adjusts the connecting form between the connecting seat and the position detecting device or the connecting form between the connecting seat and the detection unit. The chip calibration system and method have the advantages that the connecting relation between the chip and the connecting seat can be calibrated needless of using an image collector to compare chip position images, realization is simple, and tedious adjustment processes are avoided.
Description
technical field [0001] The invention relates to the technical field of chip position calibration, in particular to a chip calibration system and a calibration method. Background technique [0002] A chip is a carrier of an integrated circuit, which is formed by dividing a wafer. Chips are the most important components of controllers for electronic devices. The chip is usually connected to the corresponding connection seat on the controller substrate through pins. However, since the chip includes a more complex integrated circuit, the relationship between the pins of the chip and the connection seat should be one-to-one correspondence. If there is a deviation in the connection position between the chip and the substrate, it will cause the circuit connection of the integrated circuit to be damaged. Confusion, unable to achieve preset functions. It may even cause a short circuit in the integrated circuit, destroy the chip structure, and then damage the entire controller. ...
