Abstract

A cable having an electrostatic discharge (ESD) dissipative coating according to one embodiment includes an elongate lead; and an ESD dissipative coating functioning as an electrical insulator for the lead, wherein no other insulator excluding an optional adhesive is present on the cable. A cable having an ESD dissipative coating according to another embodiment includes at least 16 leads, and an ESD dissipative coating operatively coupled to the leads. A cable having an ESD dissipative coating according to yet another embodiment includes an elongate lead having a length defined therealong between distal ends thereof; and an ESD dissipative coating operatively coupled to the lead and extending along a majority of the length of the lead, wherein the ESD dissipative coating has an ESD dissipative surface resistance of from about 1×10 6 to about 1×10 8 ohm/sq.

Claims

exact text as granted — not AI-modified
1 . A cable having an electrostatic discharge (ESD) dissipative coating, the cable comprising: 
 an elongate lead; and    an ESD dissipative coating functioning as an electrical insulator for the lead, wherein no other insulator excluding an optional adhesive is present on the cable.    
   
   
       2 . A cable as recited in  claim 1 , wherein the ESD dissipative coating has an ESD dissipative surface resistance of from about 1×10 6  to about 1×10 8  ohm/sq.  
   
   
       3 . A cable as recited in  claim 1 , wherein the ESD dissipative coating has an ESD dissipative surface resistance of from about 0.5×10 7  to about 1.5×10 7  ohm/sq.  
   
   
       4 . A cable as recited in  claim 1 , further comprising an adhesive operatively coupling the ESD dissipative coating to the lead, the ESD dissipative coating forming a majority of an outer surface of the cable.  
   
   
       5 . A cable as recited in  claim 1 , further comprising an insulating layer positioned between the lead and the ESD dissipative coating.  
   
   
       6 . A cable as recited in  claim 1 , wherein the ESD dissipative coating is applied by spraying.  
   
   
       7 . A cable as recited in  claim 1 , wherein the ESD dissipative coating is applied by an applicator.  
   
   
       8 . A cable as recited in  claim 1 , wherein the ESD dissipative coating is a layer of polymeric material.  
   
   
       9 . A cable as recited in  claim 8 , wherein the polymeric material includes conductive materials interspersed therein.  
   
   
       10 . A cable having an electrostatic discharge (ESD) dissipative coating, the cable comprising: 
 at least 16 leads; and    an ESD dissipative coating operatively coupled to the leads.    
   
   
       11 . A cable as recited in  claim 10 , wherein the ESD dissipative coating has an ESD dissipative surface resistance of from about 1×10 6  to about 1×10 8  ohm/sq.  
   
   
       12 . A cable as recited in  claim 10 , wherein the ESD dissipative coating has an ESD dissipative surface resistance of from about 0.5×10 7  to about 1.5×10 7  ohm/sq.  
   
   
       13 . A cable as recited in  claim 10 , wherein the ESD dissipative coating has an ESD dissipative surface resistance of about 1×10 7  ohm/sq.  
   
   
       14 . A cable as recited in  claim 10 , wherein the ESD dissipative coating also functions as an electrical insulator for the lead, wherein no other insulator excluding an adhesive is present.  
   
   
       15 . A cable as recited in  claim 10 , further comprising insulating layers positioned between the lead and the ESD dissipative coating.  
   
   
       16 . A cable as recited in  claim 10 , wherein the ESD dissipative coating is applied in liquid form.  
   
   
       17 . A cable as recited in  claim 10 , wherein the ESD dissipative coating is a layer of polymeric material.  
   
   
       18 . A cable having an electrostatic discharge (ESD) dissipative coating, comprising: 
 an elongate lead having a length defined therealong between distal ends thereof; and    an ESD dissipative coating operatively coupled to the lead and extending along a majority of the length of the lead,    wherein the ESD dissipative coating has an ESD dissipative surface resistance of from about 1×10 6  to about 1×10 8  ohm/sq.    
   
   
       19 . A cable as recited in  claim 18 , wherein the ESD dissipative coating also functions as an electrical insulator for the lead.  
   
   
       20 . A cable as recited in  claim 19 , wherein no other insulator excluding an adhesive is present.
