Problems solved by technology

Moreover, after each probe card repair is completed, the engineer needs to manually reset the probe card needle insertion records on the machine, and manually record the probe card maintenance records on paper files. These paper records are very inconvenient to query. And it is not possible to check the status of all cards in time

Abstract

The invention discloses an intelligent processing system and method for a WAT probe card. The method comprises the following steps: recording and counting probe card stitching frequency in real time; detecting accumulated stitching frequency of the probe card; judging whether the accumulated stitching frequency of the probe card exceeds a set upper limit or not, if yes, testing continues, if no, turning to the next step; sending out prompt information. According to the invention, when the accumulated stitching frequency of the probe card exceeds the upper limit, an operator is warned to replace the card, the efficiency is improved, fast inquiry to the maintenance record during the entire using process of the probe card as well as the management to the state of the probe card can be achieved, and intelligent management to the WAT probe card can be achieved.

Description

technical field [0001] The present invention relates to a WAT ​​probe card management system and method, in particular to a WAT ​​probe card intelligent processing system and method. Background technique [0002] The WAT (Wafer Acceptance Test, Wafer Acceptance Test) test generally needs to connect the actual device and the test instrument through a probe card to realize the test of devices of different sizes and shapes. With the development of semiconductor technology, the structure of WAT test is getting smaller and smaller, so the tip of the probe is getting smaller and smaller. After the probe card is used for a certain period of time, due to the wear of the needle tip, the needle tip will become thicker, so the probe needs to be repaired. When the wear of the needle tip reaches a certain level, the probe needs to be replaced (rebuild). The quality of the probe card can be well controlled by determining the maintenance frequency of the probe card by the number of needle...
