Embodiment 1
[0036] see Figure 1 to Figure 7 , the embodiment of the present invention provides a double-layer PCB welding fixture, including a first base 1, the first sub-board limiting structure and the main board limiting structure are installed on the first base 1, the sub-board is positioned on the first sub-board On the limit structure of the plate, the connecting pin 5 is welded and fixed on the secondary plate 3, the main plate 4 is positioned on the limit structure of the main plate, the main plate is located above the secondary plate, the main plate and the secondary plate are parallel, and there is a gap between the main plate and the secondary plate. The connecting pins on the sub-board pass through the reserved connecting holes on the main board. The main board and the auxiliary board are horizontally supported on the first base 1 .
[0037] Further, the first sub-board limiting structure includes two sliders 6, the sliders 6 are arranged on the first base 1 without falling ...
Embodiment 2
[0047] see Figure 8 and Figure 9 , this embodiment discloses a welding fixture for PCB and connection pins, including a second base 14, at least one clamping station is arranged on the second base 14, and each clamping station of the second base 14 The upper support has at least two sub-boards overlapping up and down. The top sub-board of each clamping station is a sub-board 16 with electronic components, and the rest of the sub-boards of each clamping station do not contain electronic components. The sub-board 17 of the device, the connection holes reserved for each layer of sub-boards of each clamping station correspond to each other, and the connecting pins are inserted into the connection holes reserved for each layer of sub-boards in sequence from top to bottom, and the second Each clamping station of the base 14 is provided with a second sub-board limiting structure for limiting the position of each sub-board. The connection pins of this embodiment are inserted into ...
