Description

PCB fixing jig

[ technical field ] A method for producing a semiconductor device

The utility model relates to an electronic product technical field especially relates to a tool is fixed to PCB board.

[ background of the invention ]

The PCB board is also called a printed circuit board and comprises a base layer and a conducting layer arranged above the base layer. The base layer is an insulating layer, generally a resin composite material, the conductive layer is a copper foil layer, and the electronic component is arranged on the copper foil layer. However, in the process of assembling the PCB and the electronic component, in order to facilitate the assembly and soldering, it is necessary to develop a PCB fixing jig for fixing the PCB, so as to avoid the occurrence of poor soldering caused by the movement of the PCB during the assembly of the PCB.

In order to solve the problem, the utility model provides a tool is fixed to PCB board fixes the PCB board at PCB board and electronic component assembling process.

The utility model discloses it is not enough to solve prior art and research and propose.

[ Utility model ] content

The utility model aims at overcoming the shortcoming of above-mentioned prior art, provide a fixed tool of PCB board with the PCB board is fixed when producing.

The utility model discloses can realize through following technical scheme:

the utility model discloses a tool is fixed to PCB board, comprising a base plate, the bottom plate top is fixed with the mounting panel, be fixed with the cylinder on the mounting panel, the cylinder passes through the slider of piston rod connection below, the bottom plate upper surface still is fixed with many slide bars, the bottom plate top still is equipped with the briquetting, be equipped with the hole that aforementioned slide bar passed on the briquetting, a plurality of springs have still been placed between briquetting and the bottom plate. Place the PCB board on the bottom plate, pedal the cylinder footboard, the cylinder passes through the piston rod and promotes the slider, and the slider pushes down the briquetting, fixed PCB board, and PCB board assembly accomplishes the back, briquetting and slider separation, and the spring returns natural state, and the briquetting rises and PCB board separation takes off the PCB board that has processed from the bottom plate.

Preferably, the slide rod passes through the spring.

Preferably, a U-shaped fixing block is further fixed on the upper surface of the bottom plate, and the fixing block and the bottom plate form a limiting groove for placing the PCB. The PCB is placed in the limiting groove, so that the PCB is more conveniently positioned.

Preferably, the bottom plate is further provided with fixing columns corresponding to the through holes in the PCB. The fixed column on the bottom plate passes through the through-hole on the PCB board, and further with PCB board fixed column, avoid PCB board removal in the course of working, influence the equipment.

Preferably, the compact is made of a rubber material. The PCB is prevented from being scratched when the pressing block presses the PCB.

Preferably, the pressing block is arranged between the sliding block and the bottom plate.

Compared with the prior art, the utility model has the advantages that:

the PCB is fixed by the PCB fixing jig during PCB soldering tin assembly, so that the phenomenon that the PCB is displaced in the assembly process to influence the assembly is avoided.
