Abstract
The utility model provides a golden finger board provided with a special golden finger position. The golden finger board comprises a golden finger and a PCB (Printed Circuit Board), wherein the golden finger is arranged on the PCB and located on the surface of the PCB; and a proper distance is reserved between the golden finger and the edge of the PCB. The proper distance is reserved between the golden finger and the edge of the PCB and the position of the golden position is close to the middle of the board, so that the phenomenon that the golden finger position is slightly thin due to too much flow glue on the board edge can be prevented when the golden finger position is located at the board edge.
Description
Technical field
The utility model relates to the structure of pcb board, a kind of pcb board structure with golden finger of saying so exactly.
Background technology
The purpose of golden finger design is by the grafting of the connector outlet as the pcb board contact with foreign countries, so pcb board need have golden finger manufacturing process, and from the needs of using, the golden finger plate also is more and more at present.
Gold finger plate (pcb board with golden finger limit) is fixed on edges of boards according to conventional design Yi Bian the golden finger position has certainly, calculates according to the pressing structure theoretical value; Pressing thickness integral body is controlled at the intermediate value of customer requirement, but prepreg under HTHP, experience by solid-state to liquid after solid-state transition process, can have resin flow; And it is bigger the closer to its gummosis of edges of boards; Cause edges of boards thinner, cause the golden finger position of edges of boards thin partially, have influence on the quality and the useful life of golden finger.
Under this kind condition, how to improve the thin problem of plate of edges of boards golden finger position, effectively improve product quality, this has become enterprise to press for the problem of solution most.
Summary of the invention
Based on this, the purpose of the utility model provides a kind of golden finger plate with special golden finger position, and this golden finger plate can effectively improve and prevent the problem that gold finger plate is thin, improves the quality and the useful life of gold finger plate.
Another purpose of the utility model provides a kind of golden finger plate with special golden finger position, and this gold finger plate can reduce cost of manufacture, and production operation is convenient, and formation efficiency is higher.
For this reason, the utility model is realized according to following mode.
A kind of golden finger plate with special golden finger position, it includes golden finger, pcb board, and golden finger is arranged on the pcb board, it is characterized in that said golden finger is positioned on the surface of pcb board, and the edge of distance P CB plate has suitable distance.Golden finger distance P CB plate outer rim has suitable distance, and the position can prevent that near the centre of plate the golden finger position from too much causing the golden finger position thin partially because of the edges of boards gummosis when edges of boards.
The length and width of said golden finger are all less than the pcb board length and width, so that golden finger can invest on the pcb board, and the edge of distance P CB plate has suitable distance.
Described golden finger, the minimum distance of its distance P CB panel edges is 0.5-2.5cm, to leave suitable distance.
When producing the gold finger plate internal layer, the utility model utilization uses the assembling mode of jigsaw; With the Position Design of golden finger in centre near pcb board; Prevent the golden finger position when edges of boards because of the edges of boards gummosis too much causes the golden finger position thin partially, can effectively improve and prevent the biased thin problem of golden finger in the wiring board.
And because of the jigsaw size increases, can improve the production utilance, and the production operation handy and safe, production efficiency is higher, does not want extra increasing manufacturing facilities and other materials.
Description of drawings
The structural representation that Fig. 1 implements for the utility model.
Embodiment
Shown in accompanying drawing, the practical implementation of the utility model is elaborated.
Because the golden finger plate always has on one side the edges of boards near interior layer pattern, in the engineering of pressing prepreg under HTHP, experience by solid-state to liquid state after solid-state transition process, can have resin flow; And it is bigger the closer to its gummosis of edges of boards; Cause edges of boards thinner, cause the golden finger position of edges of boards thin partially, solve this difficult problem; Need improve the jigsaw structure, guarantee fund's finger position is not in the edges of boards position.
Therefore, in the enforcement of the utility model, as shown in Figure 1; The golden finger plate includes pcb board 1 and golden finger 2, and wherein, pcb board 1 has an outer rim 11 at least; Golden finger 2 has a nearest edge 21; Edge 21 is minimum apart from the distance of outer rim 11, and it is suitable to a that the outer rim 11 of golden finger 2 distance P CB plates 1 is had, usually should be apart from a between 0.5-2CM.
Like this structure of traditional golden finger plate is adjusted; The golden finger position is adjusted into the structure in the middle of the backup plate of golden finger position by the backup plate limit; Can effectively improve and prevent the problem that gold finger plate is thin,, reduce cost of manufacture to cut the waste; And production operation is convenient, and production efficiency is higher.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection range of the utility model.
Claims (3)
1. golden finger plate with special golden finger position; It includes golden finger, pcb board, and golden finger is arranged on the pcb board, it is characterized in that said golden finger is positioned on the surface of pcb board; The edge of distance P CB plate has suitable distance; Golden finger distance P CB plate outer rim has suitable distance, and the position can prevent that near the centre of plate the golden finger position from too much causing the golden finger position thin partially because of the edges of boards gummosis when edges of boards.
2. the golden finger plate with special golden finger position as claimed in claim 1, the length and width that it is characterized in that said golden finger are all less than the pcb board length and width.
3. the golden finger plate with special golden finger position as claimed in claim 1 is characterized in that described golden finger, and the minimum distance of its distance P CB panel edges is 0.5-2.5cm.
