Abstract
The utility model relates to an anti-deviation-and-tearing circuit board locating pin which consists of a pin and a photographic plate. The photographic plate (1) is provided with three locating holes (2) on each side. Two pilot holes (3) are arranged on both sides of the locating hole which is at the top left corner. The pin (4) with large-diameter surface is inserted in each hole. Defects of the pin used currently that the diameter of the surface of the pin is small, the locating hole is fewer, the photographic plate is often torn or the diameter of the hole is often enlarged after many times of inserting, deviation is generated on the sensitization of the circuit board and the quality of the circuit board is affected are solved. The sensitization has the advantages that the pin diameter is big, the installation is convenient, the disassembly is fast, the photographic plate is hard to tear and deviation is hard to generate, the accuracy rate of light sensation is guaranteed and the manufacture process is simple.
Description
Technical field
The utility model relates to field of tool, a kind of more precisely photographic negative and the pin of circuit board location and instrument of dismounting thereof of being used for.
Background technology
In the circuit board course of processing, all need pass through this procedure of sensitization, in order to make photographic negative and not produced error by the circuit board of sensitization, all need pin is inserted photographic negative earlier, again pin is inserted in the hole of circuit board and position, carry out sensitization then, carry out repeatedly: insert-tear open-insert-tear open ... the pin face diameter that uses is little at present, location hole is few, advances repeatedly to insert and tears open, often occurs that photographic negative is torn or the aperture enlarges, make circuit board sensitization produce deviation, influence board quality.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of photographic negative not pin and the photographic negative of easy fracture are provided.
The purpose of this utility model adopts following technical measures to realize: the utility model is made up of pin, photographic negative, it is characterized in that: respectively there are three location holes on the photographic negative both sides, on location hole both sides, the upper left corner via hole is arranged respectively, the aperture equates with location hole, be inserted with the pin of major diameter face in each hole, its diameter is 6-15mm.
Remarkable result of the present utility model, the pin diametral plane is big, and is easy for installation, and dismounting is difficult for tearing photographic negative or off normal fast, guarantees the accuracy of sensitization, and manufacture craft is simple.
Description of drawings
Accompanying drawing 1 is a structure chart of the present utility model;
Accompanying drawing 2 is an end view of the present utility model.
Below in conjunction with accompanying drawing the utility model is further elaborated.
Embodiment
Referring to figure, respectively there are three location holes 2 on photographic negative 1 both sides, on location hole both sides, the upper left corner via hole 3 are arranged respectively, and the aperture equates with location hole, is inserted with the pin 4 of major diameter face in each hole, and its diameter is 6-15mm.
Claims (3)
1, a kind of preventing offsetting and the circuit board alignment pin torn, form by pin, photographic negative, it is characterized in that: respectively there are three location holes (2) on photographic negative (1) both sides, on location hole both sides, the upper left corner via hole (3) are arranged respectively, are inserted with the pin (4) of major diameter face in each hole.
2, by described preventing offsetting of claim 1 and the circuit board alignment pin torn, it is characterized in that: the diameter of pin diametral plane is 6-15mm.
3, by described preventing offsetting of claim 1 and the circuit board alignment pin torn, it is characterized in that: via hole (3) aperture equates with location hole.
