attach polymer 27 described above one preferred way to generate and apply the electric field 45 is as part of a conveyor belt system for high manufacturing throughput electric field 45 is effective whether formed from direct current or alternating current in this process metal particles will migrate in such a manner as to complete the conductive path between the mating pad pairs 42 this migration will occur by metal disassociating from the matrix of the polymer and bridging the gaps both between metallic particles and between metallized pad and the particles in particular after a suitably long exposure to the electric field 45 the metal particle disassociation and bridging form dendrites 31 of sufficient length so that they extend between opposing pairs of pads 42 the dendrites 31 extend generally perpendicular to electric field lines 47 that is the dendrites grow anisotropically dendrites 31 formed by this process comprise both electrical and metallurgical connections to mating chip and carrier pad pairs 42 the process is continued such that many substantially parallel conductive dendrites 31 form conductive paths and metallurgical bonds for each i o pad pair 42 as shown schematically in fig2 the process of dispensing polymer 27 and inducing sufficient migration of metallic particles in polymer 27 is preferably done at temperatures in which polymer 27 is not set that is in a u201c pre set u201d form as shown in fig1 for epoxy based polymers temperatures below curing temperatures are used if a thermoplastic is used as the polymer 27 with metal particles suspended in polymer 27 the process of dispensing such thermoplastic polymer and inducing migration of metallic particles is done at a temperature above the set point so the material is fluid typically in.
