Claim 0:
1. A method of making electrical connections comprising:
providing a substrate comprising substrate electrical contacts disposed on a surface of the substrate, wherein at least one of the substrate electrical contacts has a rounded shape forming a bump, wherein (i) the surface of the substrate has a surface energy sufficient to reflow the bump into the rounded shape when the bump has been heated and (ii) the bump comprises a reflowed bead;
providing a device comprising device electrical contacts disposed on a common side of the device;
printing the device to the substrate such that each of the device electrical contacts is in electrical contact with one of the substrate electrical contacts; and
reflowing the rounded shape,
wherein each of the at least one of the substrate electrical contacts has a lateral extent over the substrate of no more than 10 μm and the device comprises a fractured or separated device tether.
