[0013] Such as figure 2 As shown, the spout of the present invention is mainly applied to the welding of electronic components 3 with short single-row leads. On the PCBA board 4 , there are no other electronic components 3 outside the single row of leads or they are relatively far away, so that the tin liquid flowing out from the tin overflow port 1 will not flow onto the electronic components 3 .
[0014] When in use, place the PCBA board at a predetermined position above the spout, and keep a certain distance between the plane of the board and the tin outlet of the spout, generally controlled at 2-4mm. The shape of the spout can be determined according to the distribution of the soldering parts of the PCBA...
