Auxiliary adhesive dispensing apparatus
An auxiliary adhesive dispensing apparatus is connected to a printed circuit board (PCB) through an opening on a side surface of a shielding cover above the PCB, and the auxiliary adhesive dispensing apparatus includes a flow guiding groove, an adhesive-injection opening connected to an end of the flow guiding groove, and a fixing part connecting the flow guiding groove and the PCB. The auxiliary adhesive dispensing apparatus is connected to a PCB through an opening on a side surface of a shielding cover above the PCB. By means of the auxiliary adhesive dispensing apparatus, an adhesive dispensing operation can still be performed after a shielding cover is mounted, so that the adhesive dispensing operation can be performed after second-reflow soldering processing.
