Abstract:
A semiconductor device (1700), which comprises a workpiece (1201) with an outline (1711) and a plurality of contact pads (1205) and further an external part (1701) with a plurality of terminal pads (1702). This part is spaced from the workpiece, and the terminal pads are aligned with the workpiece contact pads, respectively. A reflow element (1203) interconnects each of the contact pads with its respective terminal pad. Thermoplastic material (1204) fills the space between the workpiece and the part; this material adheres to the workpiece, the part and the reflow elements. Further, the material has an outline (1711) substantially in line with the outline of the workpiece, and fills the space (1707) substantially without voids. Due to the thermoplastic character of the filling material, the finished device can be reworked, when the temperature range for reflowing the reflow elements is reached.

Abstract:
A connecting part for ensuring a secure connection includes first connecting terminals that are arranged on one face of a supporting member and second connecting terminals that are arranged on the back face of the supporting member. The supporting member may have an elastic body. The connecting terminals are interconnected by conductive films which are formed on the face of the supporting member. Connecting parts are arranged between circuit boards on which electronic parts are mounted, and the circuit boards are mutually fixed in the state in which the connecting parts are compressed. The first and second connecting terminals are pushed against lands on the circuit boards by restoring force of the connecting parts, and then the circuit boards are electrically interconnected.
Abstract:
A resin containing a conductive particle and a gas bubble generating agent is supplied in a space between the substrates each having a plurality of electrodes. The resin is then heated to melt the conductive particle contained in the resin and generate gas bubbles from the gas bubble generating agent. A step portion is formed on at least one of the substrates. In the process of heating the resin, the resin is pushed aside by the growing gas bubbles, and as a result of that, the conductive particle contained in the resin is led to a space between the electrodes, and a connector is formed in the space. At the same time, the resin is led to a space between parts of the substrates at which the step portion is formed, and cured to fix the distance between the substrates.
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.
