Abstract
The utility model relates to a solder mask exposure device for a printed circuit board, which comprises an exposure main body table board, wherein, a printed circuit board is placed in the central position of the exposure main body table board, air guide grooves are formed on two sides of the exposure main body table board, air extraction holes are formed at two ends of each air guide groove, a plurality of air guide strips are arranged on two sides of the printed circuit board to be connected with the air guide grooves, and a plurality of contiguous cone-shaped bodies are arranged above the air guide strips. With the plurality of the air guide strips arranged on the two sides of the printed circuit board to be connected with the air guide grooves, the solder mask exposure device for a printed circuit board ensures that air infiltrated in the printed circuit board when being exposed can be well extracted, thereby guaranteeing the production quality of PCBs.
Description
Technical field
The utility model relates to a kind of device that is used to make printed circuit board (PCB), relates in particular to a kind of printed circuit board (PCB) green oil exposure device.
Background technology
At present industry is when the exposure of pcb board green oil is made, and usually because exposure bench vacuumizes deficiency, the problem that causes the pcb board exposure not measured influences the production quality of pcb board; If but the overlong time of bleeding can influence the raising of production efficiency again.
The utility model content
Based on the deficiencies in the prior art, problem to be solved in the utility model provides a kind of printed circuit board (PCB) green oil exposure device, and the gas that makes printed circuit board (PCB) produce in exposure process can be extracted out well, thereby guarantees the production quality of pcb board.
For addressing the above problem, the utility model provides a kind of printed circuit board (PCB) green oil exposure device, it comprises exposure main body table top, on the middle position of this exposure main body table top, be placed with printed circuit board (PCB) and be provided with air slot in the both sides of this exposure main body table top, two ends at air slot are provided with aspirating hole, and described printed circuit board (PCB) both sides are provided with several air guide bars and are connected with described air slot.
Compared with prior art, a kind of printed circuit board (PCB) green oil of the utility model exposure device is connected with oil guide groove by several Oil Guide bars are set in the printed circuit board (PCB) both sides, has guaranteed that the air that printed circuit board (PCB) infiltrates in exposure process can extract out well.
As an embodiment of the present utility model, described air guide bar top is provided with several bullets adjacent one another are.Described bullet has square or rectangular bottom surface and trapezoidal or leg-of-mutton side.
As another embodiment of the present utility model, described air guide bar is the air guide bar that the PVC material is made.
As another embodiment of the present utility model, be placed with two printed circuit board on the middle position of described exposure main body table top.
As another embodiment of the present utility model, described air guide bar is vertically installed between printed circuit board (PCB) and the air slot.
For making the utility model easier to understand, further set forth a kind of printed circuit board (PCB) green oil of the utility model exposure device below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is a kind of printed circuit board (PCB) green oil of the utility model exposure device structural representation in one embodiment.
Fig. 2 is the structural representation of air guide bar in a kind of printed circuit board (PCB) green oil of the utility model exposure device.
Fig. 3 is the local enlarged diagram of air guide bar in a kind of printed circuit board (PCB) green oil of the utility model exposure device.
Embodiment
Description is described embodiment.
With reference to figure 1, a kind of printed circuit board (PCB) of the utility model (pcb board) green oil exposure device, it comprises exposure main body table top 1, on the middle position of this exposure main body table top 1, be placed with two printed circuit board 2, and the both sides at this exposure main body table top 1 are provided with air slot 3, be provided with aspirating hole 4 at the two ends of air slot, be vertically installed with some air guide bars 5 between printed circuit board (PCB) 2 and the oil guide groove 3, attention can not allow the air guide bar cross printed circuit board (PCB) 2 or air slot 3, otherwise can influence the production quality of pcb board.Wherein air guide bar 5 can select for use the PVC material to make.
With reference to figure 2, described Oil Guide bar 5 tops are provided with bullet adjacent one another are 51, and bullet is the array proper alignment of 11*3, and 11 row's bullets are wherein vertically arranged, and every row has 3 bullets.With reference to figure 3, bullet 51 has square bottom surface and trapezoidal side.As other execution mode, bullet 51 also can be the cone with rectangular bottom surface and triangle side.This structure of air guide bar has good air guide performance, extremely important for whole device, the air guide bar is made up of a plurality of little bullet structures, just form the gap between each conelet body, when aspirating hole is bled, just can take out gas along the gap more swimmingly, make pcb board when exposure bench exposes, be in vacuum state.And when vacuumizing deficiency, cause the pcb board exposure not measure easily, so the air guide bar so designs.
To wait to make green oil exposure circuit plate and carry out green oil exposure making by normal flow; When making exposure, when pcb board is put well on the exposure machine table top, the air guide bar vertically is put between pcb board and the air slot but all can not crosses, otherwise influence the production quality; The making of green oil exposed portion has just been finished in the normal exposure air guide then.Be connected with air slot by the air guide bar being set in the printed circuit board (PCB) both sides, the bullet arrangement architecture that air guide bar top is provided with has guaranteed that the gas that printed circuit board (PCB) 2 produces can extract out from oil pumping hole 4 along oil guide groove 3 well by Oil Guide bar 5 in the green oil exposure process, thereby has guaranteed the production quality of pcb board.
Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of being done according to the utility model claim still belongs to the scope that the utility model is contained.
