Abstract:
A protective member (315) which has a surface which is coated with, for example, a conductive sheet or the like is carried upon the surface (311A) of the SAW filter (311) which has been mounted in the fitting region (313) upon the printed substrate (312). Here, within the conductive surface of the protective member (315), by surface contact with the surface (311A) of the SAW filter (311), the size of a conductive coating surface (315A) of the protective member which covers this surface (311A) is set so as to be the same as the size of the surface (311A) of the SAW filter (311), or to be smaller than the size thereof. Furthermore a shield frame member (316) which is shaped as a frame and which is made from a metal (for example from copper or the like) is provided so as to surround the periphery of the fitting region (313) for the SAW filter (311) and moreover a shield lid member (317) which is shaped as a lid and which is made from a metal (for examplefrom copper or the like) is provided so as to be sandwiched from both sides by the printed substrate (312).

Abstract:
A printed-circuit board includes an input side terminal electrode (12a) and an output side terminal electrode (13e) to be connected to the input terminal and output terminal of a SAW filter in a mounting (11) area where the SAW filter having a piezoelectric body made of langasite is mounted. Each of the terminal electrodes is connected to a micro-strip line (14) extending in parallel to but in the opposite direction to the frequency signal transmission direction (P) in the SAW filter at a position apart from the SAW filter mounting area by a predetermined distance (L). A slit (15) is provided in the SAW filter mounting area. The slit extends in the direction intersecting the frequency signal transmission direction in the SAW filter. The printed circuit board has a plurality of through holes (16) for electrical connection between its front surface and grounded back surface. Moreover, the printed circuit board has a conductive surface and a protection member in abutment with the surface of the filter. The aforementioned conductive surface of the protection member in abutment with the filter surface has a size set to be identical to or smaller than the size of filter surface.

According to a structure for inspecting the alignment of a mounted electrical component of the present invention, a wiring pattern (4) has fiducial portions (2b-e) extending closely along at least two outer edges of a rectangular electrical component (6). Accordingly, conventional silk-screen printed markers can be eliminated, resulting in a more productive and less expensive structure for inspecting the alignment of a mounted electrical component.

The invention relates to a flexible conductive tape connection enabling electrical connection between an electrical appliance (2) and an external component (1), wherein the conductive tapes (8) are located in or on a flexible foil (3), which is fixed on both the electrical appliance (2) and the external component (1). The flexible foil (3) presents a loop (6) which can be filled with an elastic material in a predetermined area running along the conductive tapes (8) perpendicular to the plane of the foil or each of the conductive tapes in the plane of the foil present a looped displacement (9) perpendicular to the length of the conductive tapes.
Abstract:
A wiring board 1 includes a base 10 having extensibility and a wiring 40 formed on the base. The wiring includes a wiring portion 20 and a conductor portion 30. The wiring portion is formed on the base and extends in a first direction P crossing (for example, perpendicular to) a longitudinal direction X of the base. The conductor portion is formed on the wiring portion and extends in the first direction. Even when the wiring board is extended along a main extension axis S in parallel with the longitudinal direction of the base, change of the resistance of the wiring is prevented. Thus, the wiring board represents stable characteristics.
