摘要:
A programmable circuit includes an array of printed groups (72,74) of microscopic transistors or diodes (40). The devices are pre-formed and printed as an ink and cured. The devices in each group are connected in parallel so that each group acts as a single device. In one embodiment, about 10 devices are contained in each group so the redundancy makes each group very reliable. Each group has at least one electrical lead (85) that terminates in a patch area (86) on the substrate (50). An interconnection conductor pattern interconnects at least some of the leads of the groups in the patch area to create logic circuits for a customized application of the generic circuit. The groups may also be interconnected to be logic gates, and the gate leads terminate in the patch area. The interconnection conductor pattern then interconnects the gates for form complex logic circuits.

A dual solder layer for fluidic self assembly, an electrical component substrate, and method employing same is described. The dual solder layer comprises a layer of a self-assembly solder (12) disposed on a layer of a base solder (14) which is disposed on the solder pad (16) of an electrical component substrate(18). The self-assembly solder (12) has a liquidus temperature less than a first temperature and the base solder (14) has a solidus temperature greater than the first temperature. The self-assembly solder (12) liquefies at the first temperature during a fluidic self assembly method to cause electrical components (10) to adhere to the substrate (18). After attachment, the substrate(18) is removed from the bath (20) and heated so that the base solder (14) and self-assembly solder (12) combine to form a composite alloy (22) which forms the final electrical solder connection between the component (10) and the solder pad (16) on the substrate (18).

A method for disposing a component comprises: a step of preparing a substrate and a first liquid; preparing a component-containing liquid containing the components and a second liquid; a step of disposing the first liquid in a hydrophilic region; a step of bringing the component-containing liquid into contact with the first liquid disposed on the hydrophilic region; a step of removing the first liquid and the second liquid to dispose the component on the hydrophilic region. The hydrophilic region is composed of a component-disposing region and a liquid-capturing region formed on the periphery of the component-disposing region. The liquid-capturing region comprises a surface represented by the following chemical formula I.

Method and apparatus for assembling a component with a flexible foil, as well as assembled product A method is provided for assembling a component (20) with a flexible foil (10). The method comprising the steps of • - providing (SI) a flexible foil (10) having a first side (11) with at least one liquid confinement zone (12) and at least one liquid confinement subzone (13) enclosed by the liquid confinement zone, • - depositing (S2) an alignment liquid (30) in the at least one liquid confinement subzone (13), • - moving (S3) the component (20) towards the liquid confinement zone, and bringing (S4) a surface (21) of the component facing the flexible foil into contact with the alignment liquid in the at least one liquid confinement subzone and releasing (S5) the component (20). The step of moving (S3) the component (20) towards the flexible foil, and the step of bringing (S4) a surface (21) of the component facing the flexible foil into contact with the alignment liquid, is realized with a gripping tool (130) that includes one or more capillary tubes (131) ending in a downward facing opening (132). At least a portion of the capillary tubes that ends in the downward facing opening (132) is filled with a carrier liquid (135). A first, adhesive force (Fal) exerted by the carrier liquid on the component is larger than a second force (Fg), that is exerted by gravity on the component and wherein said first adhesive force (Fal) is smaller than the sum (Fg + Fa2) of said second force (Fg) and a third, adhesive force (Fa2) exerted by the alignment liquid on the component when the component comes into contact with the alignment liquid. The alignment liquid (30) in contact with the component (20) exerts adhesive forces on the component that align the released component with the flexible foil.
