Embodiment Construction
[0020] The post-treatment method of a kind of PCB board tin spraying of the present invention is to carry out on a gas floating bed, and the structure of the gas floating bed is as follows: figure 1 As shown, a slide rail 4 , a first inductor 2 , a second inductor 3 , a first pin baffle 5 , a second pin baffle 6 and a swash plate 1 are provided. The inclined plate 1 is provided with a pre-cooling section 13 , a cooling section 12 and a plate-out section 11 sequentially from front to back. The first sensor 2 is installed above the front end of the pre-cooling section 13, and the first sensor 2 is used to monitor the size information of the tin plate 7, and transmit this information to the control center (not shown in the figure) of the gas floating bed. The second inductor 3 is located above the cooling section 12, and the two ends of the second inductor 3 are connected to the slide rails 4 on both sides of the gas floating bed, and the second inductor 3 is used to monitor the ...
