Abstract
The utility model discloses a printing bonding pad supporting structure. The printing bonding pad supporting structure comprises an insulating layer and a base. The insulating layer is arranged above the base, a bonding pad is arranged on the top portion of the insulating layer at the central position, a through hole is formed in the insulating layer which is located under the bonding pad, and triangular reinforcing ribs are arranged on two sides inside the through hole respectively, wherein the inner side of each triangular reinforcing rib is provided with an electrically-conductive layer. A triangular bracket is arranged in a closed cavity chamber formed by the electrically-conductive layers, and a supporting board having a triangular cross section is fixedly connected onto the top portion of the triangular bracket, wherein the upper top surface of the supporting board is pressed against the lower surface of the bonding pad. The printing bonding pad supporting structure of the utility model has the following advantages that the machining of the bonding pad is more realizable, incomplete welding caused by the reason that the bonding pad is out of flatness and collapsed can be avoided, so that the electrical connection reliability of the printed circuit board can be improved; through the added triangular reinforcing ribs, the bonding pad structure can be reinforced; and a supporting force can be given to the bonding pad which is located above the bonding pad structure from bottom for a long time so as to play a supporting role in the bonding pad.
Description
Technical field
The utility model relates to printing technology, relates in particular to a kind of printing pad supporting construction.
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 is usually firm not, and some also needs regularly safeguard or change.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 printing pad supporting construction 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 printing pad supporting construction, 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, and each triangle reinforcement inboard arranges conductive layer.
Be positioned at that enclosed cavity that conductive layer surrounds is indoor arranges a tripod, being positioned at the tripod top, to be fixedly connected with a cross section be the bottom surface that on leg-of-mutton supporting bracket and this supporting bracket, end face holds out against pad.
The beneficial effect of printing pad supporting construction 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 tripod and supporting bracket are set, can give for a long time the support force of top pad from below, thisly set up firm supporting construction below pad, supporting role is folded in butt welding.
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 printing pad of the utility model embodiment supporting construction.
In figure: 1, insulating barrier; 2, base; 3, pad; 4, triangle reinforcement; 5, conductive layer; 6, tripod; 7, supporting bracket.
Embodiment
As shown in Figure 1, the described printing pad of the utility model embodiment supporting construction, 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;
Be positioned at that enclosed cavity that conductive layer 5 surrounds is indoor arranges a tripod 6, being positioned at these tripod 6 tops, to be fixedly connected with a cross section be the bottom surface that on leg-of-mutton supporting bracket 7 and this supporting bracket 7, end face holds out against pad 3, and the height of this tripod 6 is 1.8cm.
Claims (3)
1. a printing pad supporting construction, comprise insulating barrier, base, and described insulating barrier is arranged on the base top, it is characterized in that:
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, and each triangle reinforcement inboard arranges conductive layer.
