In the solder paste printing industry, there is a growing interest in fully automatic solder paste printing machines because they have advantages that other printing machines cannot compare with. In comparison with semi-automatic solder paste printing machines, fully automatic solder paste printing machines are more outstanding in terms of printing speed, printing quality and printing accuracy, so people are increasingly choosing fully automatic solder paste printing machines. So what are the precautions for the use of automatic solder paste printing machine, the following screened the following four points of attention, I hope to provide some help for everyone in the daily use.
1. Need to pay attention to the type and hardness of the printing machine squeegee. For the choice of solder paste printing scraper, I recommend the technical scraper. Because the flatness, hardness and thickness of this squeegee are very stable and always, so that you can maintain the best quality of printing.
2. Need to pay attention to or related to the squeegee. Squeegee is the more important of the automatic solder paste printing machine precautions. Because the squeegee is directly in the printing operation, so in the time of printing, must ensure that the distance between the squeegee and FPC, the general value of the angle between 60 and 75, the angle is too large or too small will affect the final printing effect.
3. The need to pay attention to the speed of printing. In the use of printing operations, the speed should not be too fast, or it is likely to cause some places are not printed, on the contrary, the speed is too slow, it will make the printing effect is not uniform. Generally speaking, the printing speed is kept within the range of 10-25mm / s is the best, so that the printing effect can be optimized.
4. It is necessary to pay attention to the pressure of printing. It is advisable to set the pressure to 0.1-0.3kg/cm length. Generally speaking, it is best to set it at 0.1-0.3kg/per cm length. Too little printing pressure will make the amount of solder paste on the FPC insufficient, while too much pressure will make the solder paste printed too thin, while increasing the possibility of solder paste contamination on the reverse side of the metal leak board and the surface of the FPC. This printing out more evenly, there will not be too much pressure and let the solder paste printed too thin, which also avoids the possibility of side leakage in the printing process.
