Abstract
The utility model discloses a printed circuit board flexible pad structure. The printed circuit board flexible pad structure comprises an insulating layer and a base; the insulating layer is arranged on the base; a pad is arranged at a top portion at the center of the insulating layer; a through hole located below the pad is formed inside the insulating layer; two sides inside the through hole are provided with one triangular stiffener respectively; the inner side of each triangular stiffener is provided with a conductive layer; a spring assembly is arranged inside a sealed cavity which is formed through the surrounding the conductive layers; and an upper portion of the spring assembly is connected with a pressing plate. With the printed circuit board flexible pad structure adopted, the processing of the pad can be more reliable, and insufficient welding caused by roughness and collapse of the pad can be avoided, and therefore, the reliability of electrical connection of a printed circuit board can be improved; and with the triangular stiffeners additionally adopted, the structure of the pad is strengthened, and a supporting force can be provided for the pad above from below for a long time.
Description
Technical field
The utility model relates to printing technology, relates in particular to a kind of printed circuit board (PCB) elastomeric pad structure.
Background technology
Printed circuit board develops into double sided board, multi-layer sheet and flex plate from individual layer, and constantly to high accuracy, high density and high reliability future development, continuous reduced volume, Cost reduction, raising performance.Printed circuit board manufacturing technology development trend is to high density, high accuracy, fine pore, thin wire, little spacing, highly reliable, multiple stratification, high-speed transfer, light weight, slim future development on performance.The wire of single sided board wherein only appears at wherein one side, and double sided board is the extension of single sided board, can carry out the circuit of conducting between two-layer by via hole, makes it to form needed network and connects.At present, in common multilayer board, usually be followed successively by from top to bottom pad, line layer and insulating barrier, wherein pad is positioned at the upper surface of line layer, and insulating barrier is formed with through hole, sometimes, the position of pad can partly or entirely be dropped in through hole corresponding to the position of through hole, can make in this case pad processing unreliable, easily occur causing the electric connection reliability of printed circuit board (PCB) bad because of pad out-of-flatness, the rosin joint that subsides and bring; The supporting construction that it is important to point out that the pad below causes glue, China ink, dust etc. to enter in it because sealing is not enough sometimes, and is not easy to cleaning.Therefore, for above aspect, need to make rational improvement.
The utility model content
The purpose of this utility model be to provide a kind of processing comparatively reliable, be conducive to weld smooth, as can to improve printed circuit board (PCB) electric connection reliability, be conducive to improve the printed circuit board (PCB) elastomeric pad structure of wiring board printing efficiency, to solve many deficiencies of prior art.
The purpose of this utility model is carried out specific implementation by the following technical programs:
A kind of printed circuit board (PCB) elastomeric pad structure, comprise insulating barrier, base, described insulating barrier is arranged on the base top, be positioned at insulating barrier center position top pad is set, the insulating barrier that is positioned at the pad below arranges through hole and is positioned at the inner both sides of this through hole a triangle reinforcement is set respectively, each triangle reinforcement inboard arranges conductive layer, and the inside that is positioned at the sealing chamber that conductive layer surrounds arranges spring assembly, and this spring assembly top connects pressing plate.
Described pressing plate upper surface holds out against the bottom surface of pad, sets up a circle sealing ring at the pressing plate outer edge and between pad and conductive layer.
The beneficial effect of printed circuit board (PCB) elastomeric pad structure described in the utility model is:
(1) can make pad processing comparatively reliable, avoid occurring because of pad out-of-flatness, the rosin joint that subsides and bring, thereby improve the electric connection reliability of described printed circuit board (PCB);
(2) by setting up the triangle reinforcement, reinforced pad structure;
(3) by elastic mechanism and sealing ring are set, can give for a long time the support force of top pad from below, thisly set up firm supporting construction below pad, also can prevent that China ink, glue, dust etc. from entering simultaneously.
The accompanying drawing explanation
Below according to drawings and embodiments the utility model is described in further detail.
Fig. 1 is the structure chart of the described printed circuit board (PCB) elastomeric pad of the utility model embodiment structure.
In figure: 1, insulating barrier; 2, base; 3, pad; 4, triangle reinforcement; 5, conductive layer; 6, spring assembly; 7, pressing plate; 8, sealing ring.
Embodiment
As shown in Figure 1, the described printed circuit board (PCB) elastomeric pad of the utility model embodiment structure, comprise insulating barrier 1, base 2, described insulating barrier 1 is arranged on base 2 tops, be positioned at insulating barrier 1 center position top pad 3 is set, the insulating barrier 1 that is positioned at pad 3 belows arranges through hole and is positioned at the inner both sides of this through hole a triangle reinforcement 4 is set respectively, and each triangle reinforcement 4 inboard arranges conductive layer 5;
The inside that is positioned at the sealing chamber that conductive layer 5 surrounds arranges spring assembly 6, these spring assembly 6 tops connection pressing plates 7 and this pressing plate 7 upper surfaces hold out against the bottom surface of pad 3, set up a circle sealing ring 8 at pressing plate 7 outer edges and between pad 3 and conductive layer 5.
Claims (3)
1. a printed circuit board (PCB) elastomeric pad structure, comprise insulating barrier, base, and described insulating barrier is arranged on the base top, it is characterized in that:
