Abstract
The utility model discloses an air-guiding base plate used for anti-welding printing for a PCB. The air-guiding base plate used for anti-welding printing for a PCB comprises an air-guiding base plate body. A first air guiding hole and a second air guiding hole are arranged on the air-guiding base plate body. The radius of the first air guiding hole is greater than that of the second air guiding hole. The air-guiding base plate used for anti-welding printing for a PCB is a universal air guiding base plate. The first air guiding hole and the second air guiding hole, which are different in dimensions, are disposed on the air guiding base plate, thereby overcoming a problem that a conventional air guiding base plate can not be shared for use during the anti-welding jack printing for a PCB. Therefore, no special air guiding base plate needs to be designed to meet requirements of PCBs with different models during the anti-welding printing for a PCB, thereby greatly saving the storage space for the air guiding base plate, and reducing the amount and the cost of the air guiding base plate. Besides, if PCBs with different models are switched, the air guiding base plate needs not to be replaced, so that the utilization and the production efficiency of a machine stand are effectively improved.
