screen printing which is under the controlling of the computer and with low temperature setting glue, it makes the exposure parts instantaneous solidification, then come into the pattern, those parts which is not exposure can be cleaned easily. because of the semiconductor laser (led blue ray)'s wave length
is short, so its focusing spot diameter is also short, which makes the pattern on the screen is much more accurate; secondary, because of the semiconductor laser is small, it can work with multiple light, so the speeds is much quicker; third, the semiconductor laser needs less energy, and the working...
