Abstract:
A resonator/filter adapted for direct surface mounting to the surface of a printed circuit board. The resonator/filter comprises a block of dielectric material including at least one resonator through-hole extending therethrough and respective top, bottom and side surfaces defining respective regions of dielectric material covered with conductive material. The top block surface defines at least a first conductive region. A second conductive region on the bottom surface of the block defines an input/output contact which allows the filter to be mounted on the board with the bottom filter surface seated thereon, thus providing a direct ground contact between the board and the resonator through-hole for improved attenuation performance particularly at higher frequencies. A plurality of transmission line embodiments electrically interconnect the first and second conductive regions.

The second package supports the first package, and is electrically connected to the first package and has at least one joint hole. The combining member extends from the first package to below the second package to pass through the joint hole so that the combining member is partially exposed to improve the coherence between the first package and the second package.
Abstract:
An anti-breakage structure for a transmitting end of flexible printed circuitboard (FPC) is disclosed, which comprises at least a via hole, being formed on the FPC at a position corresponding to each pin of the transmitting end while enabling the at least one via hole formed on any two neighboring pins to be arranged in a staggered manner without being align on the same line. As the via holes formed on any two neighboring pins of the FPC's transmitting end are not aligned with each other but are scattered so that the area where stress is likely to concentrate is increased when the FPC is subjected to an external force, stresses can be distributed evenly through the whole transmitting end of the FPC without forming any specific stress concentration area.

A wired circuit board having terminals that can provide reliable placement of molten metals on the terminals, to connect between the terminals and the external terminals with a high degree of precision. An insulating base layer 3 is formed on a supporting board 2, and a conductive pattern 4 is formed on the insulating base layer 3 so that a number of lines of wire 4a, 4b, 4c, 4d, magnetic head connecting terminals 7, and external connecting terminals 8 are integrally formed and also first through holes 9 are formed in the external connecting terminals 8. Thereafter, after an insulating cover layer 10 is formed, third through holes 20 and second through holes 19 are formed in the supporting board 2 and in the insulating base layer 3, respectively, to communicate with the first through holes 9. This can provide the result that when the external connecting terminals 8 are connected to the external terminals 23, the connection can be performed while confirming the placement of the solder balls 21 from the respective through holes.
Abstract:
Conductive pads of a flex circuit may be electrically connected to conductive pads of a rigid circuit board. The conductive pads of the flex circuit may be sized, configured and alignable to the conductive pads of the rigid circuit board. A spacer with a plurality of apertures may be sized, configured and aligned to the conductive pads of the flex circuit and the rigid circuit board. Solder paste may be disposed between respective conductive pads of the flex circuit and the rigid circuit board within the apertures of the spacer. When the flex circuit, rigid circuit board and the spacer are assembled, the solder paste is displaced through relief vents formed through the conductive pads of the flex circuit, rigid circuit board or both the flex circuit or rigid circuit board. The solder paste is reflowed and forms a rivet structure attaching the flex circuit to the rigid circuit board as well as providing an electrical connection between the conductive pads of the flex circuit and the rigid circuit board.
