Circuitry for printer

Abstract

A printing system includes a print head to deliver ink to an image receptor and at least one ink reservoir to deliver ink to the print head. Driving circuitry provides signals to the print head to control delivery of the ink and a flexible circuit interposed between the print head and the ink reservoirs connects the driving circuitry to the print head. The flexible circuit may include a heater to provide heat to the ink reservoirs. Alternatively, the flexible circuit may be replaced with a rigid substrate having a heater within its layers.

1 . A method of providing a high-density interconnection between two members, comprising:
 applying a layer of adhesive having an array of holes to a first member having a first set of contact pads such that the holes align with the contact pads;   depositing an adhesive conductive material into the holes;   aligning a second member having a second set of contact pads such that the second set of contact pads are aligned with the holes to form an assembly; and   using a hot bar on the assembly to mechanically bond the first member to the second member.   
     
     
         2 . The method of  claim 1 , applying a layer of adhesive further comprising applying a sheet adhesive. 
     
     
         3 . The method of  claim 1 , depositing an adhesive, conductive material further comprising depositing one of a material from the group consisting of: conductive paste, silver epoxy, low melt solder paste, and indium alloy powders suspended in a flux. 
     
     
         4 . The method of  claim 1 , applying a layer of adhesive to a first member further comprising applying a layer of adhesive to a printed circuit board. 
     
     
         5 . The method of  claim 1 , aligning a second member further comprising aligning a printed circuit board. 
     
     
         6 . The method of  claim 1 , the method further comprising reusing the hot bar to the assembly and separating the first and second members.
