摘要

A method for preparing a Mask or an electronic part, such as a Printed Circuit Board, includes the steps of heat in a desired pattern.A precursor of the Mask or the Mask or electronic part, Electronic part resulting from the same unacomposicion oleofu00edlica, not sensitive to heat.And a Kit for the manufacture of such a Mask or Electronics, All relate to the use of hot forming a pattern in the composition sensitive to heat.The Method comprises the stagesof manage heat in a desired pattern of the precursor has a surface coated with a Heat Sensitive composition,Where the solubility of Aqueous Developer composition is not increased by ultraviolet radiation incident but is increased by the Administration of HeatAfter which is the Precursor to eliminate Heat Sensitive composition in regions in which heat was delivered.In the case of a precursor of a Printed Circuit, then the surface can be recorded with a Mordant or strong water conventionally Printed Circuit to obtain the required.Composition sensitive to a substance calorcomprende aqueous soluble Polymer and a compound Roll Back Revealing that Developer solubility aqueous polymeric substance and a puedenincluirAbsorber of Infrared Radiation, such as Infrared Radiation can be absorbed by the composition to produce heat in u00e1reaseleccionadas.The Radiation can be administered by an infrared laser under Digital Control.The fact that the composition is Inert to radiacionultravioleta wants to say that you do not need special Secure irradiations.
