  • Patent number: 12140618
    Abstract: A probe cleaning sheet for preventing a probe pin damage and manufacturing method thereof, during the process of a probe pin puncturing the cleaning layer, the material of the cleaning layer and the plurality of high and low density cleaning particles of abrasive material contained in the high density cleaning material and the low density cleaning material are able to efficiently scrape away foreign material from the surface of the probe pin. In addition, the negative charge carried by the silicone itself and its lipophilic characteristics are used to transfer the foreign material on the probe pin to the cleaning layer, and the protective layer is used to prevent overpressure from the probe pin directly impacting the substrate and causing damage to the tips of the probe pin.

  • Publication number: 20240359293
    Abstract: A probe cleaning sheet and a manufacturing method thereof are provided. The manufacturing method includes material preparing step, first printing step, first baking step, first cooling step, second printing step, second baking step, and second cooling step. The probe cleaning sheet includes a silicone glass fiber cloth layer and an abrasive layer set printed on one side of the silicone glass fiber cloth layer. The silicone glass fiber cloth layer includes a plurality of glass fibers and silicone, the silicone is coated on the surface of the glass fibers and in the gap between the glass fibers. The abrasive layer set includes a high-density abrasive layer printed on one side of the silicone glass fiber cloth layer and a low-density abrasive layer printed on the top surface of the high-density abrasive layer and is opposite to the silicone glass fiber cloth layer.

  • Publication number: 20230166297
    Abstract: A probe pin cleaning sheet with cleaning power and a manufacturing method thereof are disclosed, comprising a release layer, a cleaning layer, and a substrate. Thus, in the process that the probe pin pierces the cleaning layer, through the material of cleaning layer, and the cleaning grains of abrasive material contained in the cleaning material in the cleaning layer, the cleaning power is increased to scrape off dirt from the surface of probe pin. In addition, by the negative charges and lipophilic property of the silicone itself, the dirt on the probe pin can be transferred onto the cleaning layer.
