Description

Technical Field

[0001] The utility model relates to the technical field of PCB board glue dispensing processing, in particular to a fixture used for PCB board glue dispensing. Background Art

[0002] Now the chip components have become the mainstream. At present, the double-layer chip is directly pasted on the PCB board and then placed on the fixture for furnace welding. The component's plate will be tinned and soldered. There is also a part that the fixture is placed on the dispensing device for dispensing. The dispensing fixture mainly plays the role of fixing the PCB board and is convenient for the dispensing of the PCB board. In the production of electronic products, for large BGA (Ball Grid Array, solder ball array package), it is necessary to point the bottom filling glue to reinforce the device and enhance the anti-drop performance of the BGA packaged chip. At the same time, for waterproofing purposes, the exposed devices on the semi-finished motherboard need to be coated with waterproofing on the whole board. In the process of dispensing production, the glue is sprayed from the nozzle of the dispensing machine equipment to the device. At the moment, there will be a small amount of glue splashing and falling on some connectors close to the dispensing device, such as contact springs, BTB (board-to-board connector) strips, RF (radio frequency) heads and other devices. If these connectors are contaminated by the falling glue, it will directly lead to poor contact during the assembly process, affecting the performance of electronic products and bringing quality risks.

[0003] However, in the prior art, the existing dispensing fixture structure is too simple, and the PCB board is not firmly fixed, which may easily cause it to fall off the fixture. At the same time, the PCB board may be damaged due to being fixed too tightly. Moreover, the current dispensing fixture cannot be adjusted according to the size of the PCB board, and can only be fixed to one type of PCB board, which seriously reduces the dispensing efficiency.
