Abstract:
In a process for assembling a microstructure (1), provision is made of a first microstructure piece (2) having a receiving recess (3) in its surface and a second microstructure piece (5) having a connecting region (6) fitting into the receiving recess (3) and on which is arranged at least one electrical contact element (7a, 7b). Provision is made of a flexible cable (8) having a flat substrate layer (9) made of an electrically insulating material and at least one strip conductor (10) arranged thereon. The cable (8) has at least one tongue (14a, 14b) on which is arranged at least one counter-contact element (11a, 11b) connected to the strip conductor (10). The cable (8) and the microstructure pieces (5) are positioned relative to each other in a preassembly position in which the connecting region (6) is opposite the receiving recess (3) and the tongue (14a, 14b) is aligned between the connecting region (6) and the receiving recess (3). The connecting region (6) is then introduced in the receiving recess (3) by displacement of the microstructure pieces (2, 5) toward one another. In doing so the at least one tongue (14a, 14b) is deflected in the receiving recess (3) in such a way that the at least one counter-contact element (11a, 11b) contacts the at least one contact element (7a, 7b).
Abstract:
An electronic apparatus includes metal wiring plates placed together in the same plane to provide a wiring circuit, electronic devices mounted to the wiring plates through a solder, a case having a base portion and columnar portions extending from the base portion. The wiring plates are fixed to the columnar portions such that the wiring circuit is spaced from the base portion. The wiring plates have an enough thickness to resist a large current for operating the electronic devices and to release heat generated by the electronic devices. The wiring circuit is spaced from the base portion of the case so that the heat generated by the electronic devices is released in the space efficiently. The electronic devices are soldered to the wiring plates at once in a thermal reflow process.
Abstract:
The present invention provides a motor that enables a lead of a coil to be appropriately led through holes, while allowing the lead of the coil to be fixed without contacting a wall surface of the hole in a base. Cuts 14b are formed in an insulating sheet or a printed circuit board 14; the cuts 14b extend substantially radially or spirally from a lead lead-out portion 14a as a center. Thus, even if an end of the lead 7a abuts against an area located outside the lead lead-out portion 14a, the abutting area and a nearby area located in the vicinity of the abutting area are pushed open along the cuts 14b extending from the lead lead-out portion 14a and guide the end of the lead 7a toward the lead lead-out portion 14a. The end of the lead 7a is thus appropriately guided into the lead lead-out portion 14a.

A magnetic head assembly is provided. The magnetic head assembly includes a slider in which a head element is mounted. A flexure supports the slider. The flexure includes a pair of outriggers, a connection portion, and a tongue portion. A flexible wiring substrate is fixedly bonded to the surface of the flexure. An electrode pad of the slider and an electrode pad of the flexible wiring substrate are bonded to each other by solder. A plurality of solder bonded portions are arranged on the connection portion. A deformable portion is formed in the pair of outriggers and located on an extended line on which the solder bonded portions are arranged, so that the free end side of the flexure is deformable.
