[PCB Printing] PCB Circuit Board Printing UVLED Light Source

The PCB circuit board UV machine uses LED chip as the PCB optical solidification UVLED machine with the luminous body. It is different from PCB optical curing machines such as mercury lamps and halogen lamps. The overall light power is relatively small (compared to the overall light power of mercury lamp) to completely solidify. The calories and power consumption generated by the PCB circuit board UVLED machine are lower than that of the traditional PCB optical curing machine. PCB circuit board UVLED machine principle: adding light cause (or photoretinomers) to the resin of a special formula, and after absorbing the high -strength ultraviolet light in the ultraviolet (UV) optical device Polymerization, cross -linking, and branching reactions make resin (UV coatings, ink, adhesives, etc.) transformed from liquid to solid state within a few seconds (no). PCB optical solidification UVLED light source PCB ink characteristics: (1) viscosity: so -called viscosity is the internal friction of the liquid, which means that under the action of external forces, the liquid slides on the other layer of liquid, and the inner liquid is applied by the inner liquid. The friction force makes the PCB printing ink will not be scratched by foreign objects. (2) Tacticalness: Tentile is a physical characteristics of liquid, that is, its viscosity decreases in the stirring state, and after static, it will quickly recover its original viscosity characteristics. By stirring, the effect of tactile degeneration continues for a long time, which is enough to make its internal structure reconcile. To achieve high -quality net printing effects, the tactileness of ink is very important. (3) Fineness: The fillers of pigments and minerals are generally solid. After fine grinding, its particle size does not exceed 4/5 microns, and in a solid form to form a homogeneous liquidity state. Therefore, it is very important to require ink to have fineness.
