How to clean the stains on PCB quickly?Using manual cleaning requires a lot of manpower and the quality does not necessarily meet the customer's requirements, and the cost of human resource is high and the productivity is low.In the face of these problems, we suggest that you use runqia's laser eraser, which has the functions of "direct discharge without fixture" and "360 degree free placement of PCB board", as well as the light curtain sensor to prevent the board from being removed in advance.At the same time, the speed, power and structure design of the equipment have been greatly improved, and the technology in the PCB board wiping industry is more advanced. The application of the equipment greatly reduces the use and dependence of the technicians in the PCB board wiping technology, and the operation is simple.The working mode of the laser eraser: the laser outputs the laser of a specific wavelength, and then the ultra-high speed scanning galvanometer makes the laser clean the materials to be cleaned according to the set trajectory. The oil or dust on the gold finger is separated from the evaporation after being irradiated by the laser to realize the cleaning function.The circuit board has stronger conductivity, better contact and better bonding effect. The wiping speed is more than 5-10 times of the traditional manual wiping speed, thus improving the productivity.
