Welding tool for electronic components
Technical Field
The invention belongs to the technical field of electronic processing equipment, and particularly relates to a welding tool for an electronic component.
Background
In the production of electronic equipment, the welding of a circuit board is the main work, in the welding of electronic components, the electronic components are firstly inserted on the circuit board and then welded on the circuit board, in the welding of the circuit board, a welding tool is needed for positioning and fixing the circuit board, and the welding tool generally positions the corners or holes of the circuit board and compresses the edge of the circuit board.
