Embodiment Construction

[0042] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, and components have not been described in detail so as not to obscure the present invention. Ink formulations can be provided that are designed to support LED curing and that can be chemically tuned for curing by a single wavelength generated by the LED.

[0043] The terms irradiating, exposing and irradiating are used interchangeably in this specification.

[0044] Additionally or alternatively, to ensure uniform curing both of the surface and deeper areas of the coating, some wavelengths may be generated by the LED illumination module. This can result in the use of several LED devices, each having a wavelength effective at the respecti...

Abstract

A method for printing a pattern on a electrical circuit, the method includes jetting on the electrical circuit an ultraviolet curable ink to form a pattern; and at least partially curing the ultraviolet curable ink by exposing the pattern to ultraviolet radiation generated from at least one ultraviolet light emitting diode (LED).

Description

[0001] related application [0002] This application claims priority to US Provisional Patent Serial No. 61 / 437717, filed January 31, 2011. technical field [0003] The present invention relates to ultraviolet light emitting diodes for curing UV reactive inks. Background technique [0004] UV reactive ink types (solder mask as an example) are typically cured using broadband ultraviolet (UV) light radiation emitted from a broadband mercury bulb / mercury bulb doped with metal halides such as lead, iron, etc. . [0005] Proper curing of the ink is absolutely essential to the success of the coating process. [0006] UV light radiation is a well-known source for curing UV-based materials during the inkjet printing stage. The material includes agents designed to react with the wavelength provided by the curing light source. The most common sources for UV use arc lamp technology. Arc lamps offer a wide range of wavelengths. Some of these wavelengths are effective at curing the...
