Embodiment Construction

[0025] The application implementation of the product involved in the present invention is based on the current printed circuit board production equipment and process, that is, the product can be applied without adding, reducing and adjusting the equipment and changing the manufacturing process. The specific implementation process is further described. First, prepare the water-based reaction kettle, add o-cresol epoxy resin, acrylic acid and catalytic amount of triethylamine in a certain molar ratio, react at 90 to 110 ° C for 6 hours, and measure the acid value to the acid value. When it is zero, stop the reaction. Cool to room temperature (20~35℃), then add triethylamine hydrochloride dropwise, keep the temperature at 80~90℃ and react for 3 hours, until the solution is clear, the measured epoxy value is close to zero, stop the reaction, cool, That is, the synthesis of the water-based phenolic epoxy acrylic resin is completed.

Abstract

In order to overcome the defects of the traditional liquid photoimagable etching and plating resist ink during use, the invention provides novel etching and plating resist ink of a hydrophobic printed circuit board. The ink can realize mutual benefits of social benefits and economic benefits on the aspects of environment protection, labor protection, water resource and electric energy saving, improved manufacture efficiency and reduced cost of the printed circuit board, and the like without using an organic solvent, is a novel environmental-friendly, economic and energy-saving product according with the 3E (Efficacy, Efficiency and effectiveness) idea, and can replace the traditional generally used liquid photoimagable etching and plating resist ink to be applied under the condition of no change of equipment and conditions of the process and the manufacture procedure of the traditional printed circuit board.

Description

technical field [0001] The invention relates to a screen-printed circuit ink used in photoimaging of copper clad laminates in the manufacture of printed circuit boards, in particular to circuit inks of water-based printed circuit boards. Background technique [0002] At present, in the manufacture of printed circuit boards, the resists used for photoimaging are mainly divided into two types, namely dry film and wet film. Due to its limited photoimaging and high cost of use, dry film is not widely used. The current wet film products mainly include liquid photosensitive circuit ink, UV-curable circuit ink, etc. They are all organic solvent inks. Among them, liquid photosensitive circuit ink is the most used in the manufacture of printed circuit boards, and the production technology and application process are also the most mature. [0003] The invention is mainly aimed at some deficiencies in the production and use of liquid photosensitive circuit inks. The main shortcomin...
