Description

PCB air guide plate

Technical Field

The utility model belongs to the air guide plate field, concretely relates to PCB air guide plate.

Background

In the manufacturing process of the PCB, the holes on the PCB are plugged by an ink hole plugging process, so that the problem that when the PCB is pasted with electronic elements, the electronic elements on the front side and the back side are connected by tin due to the fact that tin balls penetrate through the holes, and short circuit is caused is solved. And in printing ink consent technology in-process, because the PCB board of plane placement makes the one end in hole sealed, printing ink is difficult to the entering downthehole because of downthehole air printing ink that exists when getting into from the other end, the air guide backing plate is filled up to the general solution below the PCB board, drill on the backing plate, the hole position of drilling position correspondence PCB board, make printing ink can get into smoothly in the PCB board is downthehole, however the PCB plate hole quantity of each model, the position is all different, the PCB board that leads to every model all need make corresponding air guide backing plate when carrying out printing ink consent technology, waste time and energy, the cost is higher, the process is loaded down with trivial details.

SUMMERY OF THE UTILITY MODEL

Therefore, in order to solve the above problems, an object of the present invention is to provide a PCB air guide plate, which includes an outer frame, a grid frame and a fixing member for fixing the outer frame on a table top;

the outer frame is hollow, a PCB positioning component is arranged on the frame on the upper side of the outer frame, the grid frame is connected to the inner edge of the outer frame, the fixing component is connected to the outer edge of the outer frame, and the fixing component can be matched with the pin and the pin hole to enable the air guide plate to be firmly fixed on the operation table top;

the grid frame is provided with linear bulges, and the linear bulges can support the PCB.

Further, the PCB positioning component is a positioning nail.

Furthermore, the PCB positioning component is connected to the outer frame in a sliding mode, a sliding groove is formed in the frame on the upper side of the outer frame, the positioning nail can slide in the sliding groove, the PCB can slightly move after being fixed, and the linear protrusion is prevented from blocking the hole of the PCB just.

Further, the fixed part is hinged to the outer frame, a through hole is formed in the fixed part, the through hole facilitates manual grasping, the air guide plate is convenient to move, and the through hole can be matched with a pin and a small hole to enable the rice wife plate to be fixed on the operation table board.

The utility model has the advantages that:

set up net rack and linear arch, make the PCB board erect on the net rack, the below is ventilated, makes printing ink can be full of in the PCB diaphragm orifice, and linear arch makes the area of contact of PCB board lower surface littleer, and the ventilation effect is better, and is applicable to the PCB board of multiple different shapes.
