    Adjustment and influence of process parameters of SMT printing press

    1. The angle of the scraper The angle of the scraper affects the vertical force of the scraper on the solder paste. The smaller the angle is, the greater the vertical force is. The pressure can be changed by changing the angle of the scraper. If the scraper angle is greater than 80 degrees, the s...

    Welding SMT circuit board of wave soldering machine

    There are two technical difficulties in welding SMT circuit board with general wave soldering machine. (1) Bubble occlusion effect. During the welding process, the bubbles produced by the volatilization of flux are not easy to be discharged, which may shield the solder from contact with the weld...

    Printing Performance of SMT Solder Paste

    In the mass production of SMT, solder paste must be transferred to PCB smoothly and continuously through solder paste leak board or distributor. If the solder paste is not printed well, the holes in the leak board will be blocked and the production can not proceed normally. The reason is the lack...
