  • Publication number: 20250053161
    Abstract: A manufacturing control method is applied to a computer system comprising a processor, a storage device, and a display device. The manufacturing control method includes: dividing a plurality of outlier-filtered data into a plurality of data subgroups based on a group division reference value; calculating a plurality of standard deviations for each of these data subgroups; calculating a warning line upper limit and a warning line lower limit based on the group division reference value, a predetermined multiple, and the standard deviations; adjusting either the warning line upper limit or the warning line lower limit based on the predetermined multiple and the standard deviations; and when a sensing data exceeds the warning line upper limit or the warning line lower limit, the computing system triggers a warning signal.

  • Publication number: 20240361354
    Abstract: A method for detecting a contact force of a probe card is provided. The method includes contacting a pressure film sensor with a plurality of needles over a lower surface of the probe card. The method includes detecting the contact force of the probe card via the pressure film sensor. The method also includes adjusting a position of a push base over an upper surface of the probe card based on the detected contact force of the pressure film sensor.

  • Patent number: 12055563
    Abstract: An apparatus is provided. The apparatus includes a stage and a plate disposed on the stage. The apparatus further includes a pressure film sensor that is formed on the plate and configured to detect a contact force between a plurality of needles on a probe head of a probe card and the pressure film sensor. The apparatus still includes a distance detector that is configured to detect a distance between the pressure film sensor and the needles. In addition, the apparatus includes an adjustment driver that is configured to adjust the probe card based on the detected contact force of the pressure film sensor.

  • Publication number: 20190074051
    Abstract: A refresh control method for a memory system is provided. The memory system includes a dynamic random access memory with a register set and a memory cell array. The refresh control method includes the following steps. Firstly, a masking command or an unmasking command is issued, and thus the register set is updated. A first region of the memory cell array is set as a masked region according to the masking command. A second region of the memory cell array is set as an unmasked region according to the unmasking command. Then, a refresh command is issued to the dynamic random access memory. According to the refresh command, a refresh action is performed on the second region of the memory cell array.
