Abstract

The invention relates to a packaging method for combining a screw to a printed circuit board, which is a method for combining the screw to the printed circuit board by a surface adhesion technique and comprises the following steps: providing a screw having a screw head, a screw rod extending out of one end of the screw head, and a sleeve sleeved on the periphery of the screw rod and movably arranged on one end face of the screw head; sleeving a limit ring on the screw rod to lean against one end of the sleeve so that part of the sleeve is limited in the screw head; arranging an adhesive layeron the other end face of the screw head; providing the printed circuit board with a plurality of through holes and arranging a soldering tin layer; making a tool use the screw through the adhesive layer and moving the tool so that the screw rod corresponds to the through holes; making the tool release the screw to drop the screw, and arranging a flange of the sleeve in the through holes; heating the soldering tin layer to melt tin, and cooling the soldering tin layer to the normal temperature so as to harden the soldering tin layer; fixedly arranging the sleeve in the through holes; and removing the limit ring. The method has the efficacy of achieving precise, non-offset, non-deflective and easy arrangement in the process of arranging a screw sleeve.

Description

technical field [0001] The invention relates to a packaging method for combining screws with a printed circuit board, in particular to a packaging method for combining screws with a printed circuit board, which can achieve the functions of precision, no deviation, no skew and easy setting when setting the screw sleeve method. Background technique [0002] see Figure 1 to Figure 5 as shown, figure 1 It is the structural representation of the existing screw Figure 1 , figure 2 is a structural representation Figure II , image 3 It is a schematic illustration of the conventional packaging method of combining screws with printed circuit boards Figure 1 , Figure 4 is a gesture Figure II , Figure 5 is a gesture Figure three . Generally, the existing customary method of combining screws on a printed circuit board is to use a screw 5 with a screw head 51, a screw rod 52 and a sleeve 53 to correspond to the perforation of a printed circuit board 7 with the sleeve ...
