Probe end cleaning sheet

Abstract

To remove foreign matter without deforming the end of a probe, and prevent new foreign matter from adhering to the end of a probe. A probe end cleaning sheet for removing foreign matter adhered to the end of a probe 211 , comprising a cleaning thin film 110 having fine abrasive powder applied on the surface, an elastic sheet 120 provided in a lower layer of the cleaning thin film 110 and having an elasticity, and a board 130 provided in a lower layer of the elastic sheet 120 , in which the cleaning thin film 110 is made of a material which is dented when the end of the probe 211 is pressed with a specified load but is not torn by the end of the probe 211 , and the elastic sheet 120 is made of a material which is dented in the pressed portion by the end of the probe 211 when the end of the probe 211 is pressed to the cleaning thin film 110 with the specified load.

1 . A probe end cleaning sheet, being a probe end cleaning sheet for removing foreign matter adhered to the end of a probe, comprising a thin film for cleaning having fine abrasive powder applied on the surface, an elastic sheet provided in a lower layer of this thin film for cleaning and having an elasticity, and a board provided in a lower layer of this elastic sheet, wherein said thin film for cleaning is made of a material which is dented when the end of the probe is pressed with a specified load but is not torn by the end of the probe, and the elastic sheet is made of a material which is dented in the pressed portion by the end of the probe when the end of the probe is pressed to the thin film for cleaning with said specified load.  
     
     
         2 . A probe end cleaning sheet, being a probe end cleaning sheet for removing foreign matter adhered to the end of a probe, comprising a metal thin film for cleaning made of a metal having a hardness nearly same as or larger than that of the material for composing the probe, having a rough surface, an elastic sheet provided in a lower layer of this metal thin film for cleaning and having an elasticity, and a board provided in a lower layer of this elastic sheet, wherein said metal thin film for cleaning is made of a material which is dented when the end of the probe is pressed with a specified load but is not torn by the end of the probe, and the elastic sheet is made of a material which is dented in the pressed portion by the end of the probe when the end of the probe is pressed to the metal thin film for cleaning with said specified load.  
     
     
         3 . A probe end cleaning sheet of  claim 1  or  2 , wherein said specified load ranges from several grams to scores of grams.
