Double-Sided continous-dryers Application: Uv curing and uv post-polymerisation of photoimageable soldermask on printed circuit boards and flex-boards. Advantages: The developed soldermask will be final uv cured in addition to the final thermal curing process. The postpolymerisation process improves the surface characteristics of the solder mask regarding resitance to chemicals in the nickel gold bath, during hot air levelling, in chemical or galvanic tin bath along with the electric surface properties. Exposure time can be reduced to a minimum because the final properties are realized by uv polymerisation.
