A terminal connecting method including: removing a insulation film by a predetermined length from one end of a litz wire; inserting to a pressure fixing part a terminal part of the litz wire; compressing a first portion of the pressure fixing part with a first compression force to cause plastic deformation of an entirety of the pressure fixing part, and to temporarily fix the terminal part of the litz wire to the pressure fixing part; compressing a second portion of the pressure fixing part with a second compression force greater than the first compression force to locally cause plastic deformation of the pressure fixing part and the litz wire, the second portion being a part of the first portion; and pouring molten solder from a front end side of the pressure fixing part to firmly fix the litz wire to the terminal metal fitting.

A terminal connection structure for an electric wire end portion (12a) in which the electric wire end portion is soldered being exposed on a flat-plate terminal piece (11b) out from inside of a terminal main part (11a), the terminal piece being continuous with a front end of the terminal main part (11a). The electric wire end portion (12a) exposed on the terminal piece (11b) from the terminal main part (11a) includes a first end section (12a1) that is close to the terminal main part (11a) and a second end section (12a2) that is far from the terminal main part (11a). The electric wire end portion (12a) has a shape, in side view, such that the first end section (12a1) is compressed to have a gentle curved surface that approaches the terminal piece (11b) toward the second end section (12a2).

The invention is a hand-held portable device for soldering electrical wires to an LED lighting strip. The device comprises mechanisms for positioning and securing LED strip contact pads, wires, and solder in position in proximity to a heating element. When the heating element is engaged, solder is melted and forms a bead which connects the wires to the LED strip contact pads. Various configurations of the device are described, as are methods of using such devices to connect LED strips to power sources.

A flexible circuit board includes a center rigid section, such as a printed circuit stack, and an adjoining flexible multi-layer body that are fabricated from a common interconnect layer. A transition material is included at the interface between the center rigid section and the flexible multi-layer body to minimize ripping and cracking of the interconnect layer. The transition material can also be added at stress areas not related to the interface. The transition material is attached at the interface and stress areas of the flexible circuit board in order to strengthen the flexible circuit board in general and in particular the transition material included therein. The transition material layer is formed and deposited at one or more locations on or within the flexible circuit board in order to minimize, reduce, if not prevent cracking and ripping of the flexible circuit board as it is bent, flexed and/or twisted.
