Abstract
The utility model provides an AGP graphics card, the golden finger of which consists of a plurality of the upper bonding pads and the lower bonding pads. The upper bonding pad and the lower bonding pad array crossing up-down in turn, the distance between the bottom edge of the upper bonding pad and the bottom edge of the PCB board is the range from 3.453mm to 3.707mm, the optimized distance is 3.58mm; the distance between the top edge of the lower bonding pad and the bottom edge of the PCB board is the range from 3.533mm to 3.787mm, the optimized distance is 3.66mm; the corresponding wide borders of the upper and lower bonding pads are arc, the distance between the two bonding pads is 0.20mm; the golden finger of the AGP graphic card not only can ensure to accord with the golden finger size requirement of the AGP2.0 criterion, but also can extend the contact area, can contact with the slot preferably, reduces the computer fault, and more beneficial to the manufacture of the PCB board factory to reduce the process cost.
Description
Technical field
The utility model relates to video card, is specifically related to the AGP video card of the built-in golden finger structure with improvement of a kind of computer.
Background technology
The golden finger structure of the AGP video card of prior art as shown in Figure 1, comprise the some tops pad and the some bottoms pad that are located on the pcb board, described top pad and bottom pad are staggered up and down successively, pad is wide to be 1.09mm, the top margin of pad base, top and bottom pad is at a distance of 0.2mm, to be pad base, 1mm top apart from the base of pcb board greatly enhance most centre distance is 3.70mm between pad, and bottom pad top margin is the minimum long 3.50mm that is apart from the base of pcb board.AGP (Accelerated GraphicsPort Accelerated Graphics Port) video card is the main flow graphics process video card of present microcomputer, the data volume that system passes to the figure control chip through the AGP groove is big, the speed of signal is fast, the contact resistance at its docking port place requires higher, the golden finger of the slot of computer main board AGP and AGP video card in theory all should be by the standard processing of AGP2.0, and the standard of AGP2.0 has been done the size restrictions of a closure to the golden finger of AGP video card, do not allow the dimensional discrepancy of a bit, this production equipment and manufacturing technology to PCB manufacturer requires very high, the scrappage of pcb board is increased, and cost is high.
The utility model content
The technical problems to be solved in the utility model is, a kind of AGP video card is provided, can guarantee that the utility model meets the AGP2.0 standard to the golden finger dimensional requirement, can enlarge contact area again, guarantee to contact with the good of slot, reduce electric angry fault, and more help the production of pcb board producer, reduce the processing cost of pcb board.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of AGP video card, its " golden finger " comprises some tops pad and the some bottoms pad that is located on the pcb board, described top pad and bottom pad are staggered up and down successively, pad space length 0.20mm, it is characterized in that, described top pad) base is 3.453～3.707mm apart from the bottom side length of described pcb board, the top margin of described bottom pad is 3.533mm～3.787mm apart from the bottom side length of described pcb board, and the described top and the bottom relative broadside of pad is an arc.
In order to obtain better effect, pad base, described top is 3.58mm apart from the bottom side length of described pcb board, and the top margin of described bottom pad is 3.66mm apart from the bottom side length of described pcb board.
Compared with prior art, the utility model has changed " golden finger " length of pad up and down, pad relative broadside in top and the bottom changes arc into, protect the face-bonding disk space apart from 0.20mm, the regulation that had both met the standard of AGP2.0 has overcome the size restrictions of the standard of AGP2.0 to the golden finger closure of AGP video card again, and the utility model AGP video card more can adapt to various AGP slots, assurance AGP slot shell fragment contacts with AGP video card golden finger, guarantees the transmission of high speed signal; It avoids the AGP video card not start shooting because of contact problems cause computer, reduces the computer glitch rate; Make things convenient for the production of pcb board manufacturing factory, reduced the cost of pcb board.
