Whether or not a lead wire has been normally cut and clinched can be reliably detected. A contact pipe is arranged in lead wire insertion holes of a pair of fixed pawls in a state of being electrically insulated from the fixed pawls. In a case where the lead wire is shorter than a set length after the lead wire is inserted into the lead wire insertion holes, a clearance of the pair of lead wire insertion holes is widened by a set amount in the event of outward bending of the lead wire and is narrowed by a set amount in the event of inward bending. A cut-and-clinch operation is performed with S4 bypassed in a case where the length of the lead wire is at least the set length.

A method of assembling a light source comprises the steps of inserting multiple lead wires of a light emitting element into an insertion hole formed in a circuit board from one side of the circuit board at once, striking tips of the multiple lead wires with corresponding multiple guides formed on a circumference of a pressing device serving as a jig from the other side of the circuit board, moving the pressing device toward the one side from the other side of the circuit board, and in a first stage guiding the multiple lead wires to corresponding terminals formed in an inner wall of the insertion hole of the circuit board, respectively.

Embodiments of the invention provide a method of manufacturing a printed circuit board, including: mounting a strip substrate on a fixing member; separating the strip substrate into unit substrates by performing a singulation process; attaching solder balls onto the unit substrates using a jig; and fixing the solder balls on the unit substrates by performing a reflow process. The method of manufacturing a printed circuit board is advantageous in that the solder balls can be accurately formed at the predetermined positions of the strip substrate because they are attached to the unit substrates after the warpage of the strip substrate was reduced by a singulation process.

Provided are an opto-electric hybrid board and a manufacturing method therefor. An optical waveguide unit includes protruding portions which are extendingly provided at portions of at least one of an undercladding layer and an overcladding layer, and the protruding portions are located and formed at predetermined locations with respect to a light transmitting surface of a core. An electric circuit unit includes a bent portion having fitting holes into which the protruding portions fit and having an optical element. The fitting holes are located and formed at predetermined locations with respect to the optical element. The optical waveguide unit and the electric circuit unit are coupled to each other in a state in which the protruding portions fit into the fitting holes to form an opto-electric hybrid board.

This is directed to a power adapter plug arm manufactured from a single piece of material. The plug arm can include a plug operative to extend into a wall socket, an elongated plate coupled to an end of the plug such that the plug extends from a first surface of one end of the plate, and a pin coupled to the opposite end of the plate and extending from the opposite surface of the plate. The pin can be operative to engage a circuit board of the power adapter to provide power received from the wall socket to an electronic device coupled to the power adapter. To enhance the strength of the plug arm, the plate can be manufactured by creating a co-axial plug and a stem from a single piece of material, bending the stem, and cold heading the bent portion of the stem to form a plate. Because the cold heading process involves cold working the material, the arm and in particular the bridge member at the interface between the plate and the stem can become stronger as a result of the manufacturing process.

A methodology for connecting device components with circuitry located at different levels and orientations relative to one another is described. First circuitry can be located on a multi-plane rigid circuit board where the multi-plane rigid circuit board can include at least one flexible member sharing a common substrate with the multi-plane rigid circuit board that extends from a body portion of the multi-plane rigid circuit board. The flexible member can include traces used to convey power and/or data and an interface coupled to the power and/or data traces. The flexible member can be deflected or twisted to connect first circuitry on the body portion of the multi-plane rigid circuit board to second circuitry associated with another device component.
