The invention discloses liquid photosensitive solder resist white oil and a manufacturing method thereof. The liquid photosensitive solder resist white oil is prepared from a main agent and a curing agent according to a mass ratio of 4: 1. The manufacturing method of the liquid photosensitive solder resist white oil comprises the following steps of mixing the main agent and the curing agent according to a mass ratio of 4: 1, stirring uniformly, carrying out silkscreen of the mixture on a printed circuit board (PCB), carrying out prebaking, and carrying out irradiation by active energy rays until a Stouffer level reaches a level of 9 to 12. The liquid photosensitive solder resist white oil has excellent photonasty (light sensitivity) and can be cured rapidly. The liquid photosensitive solder resist white oil can be developed by a dilute alkali solution and form patterns, and can form a cured film by thermocuring in a post-curing process, wherein the cured film has good adhesiveness and high-temperature resistance.
Description
technical field [0001] The invention relates to a liquid photosensitive solder resist white oil used for manufacturing precision circuit boards and emerging LEDs and a preparation method thereof. Background technique [0002] Similar products are easy to change color after high temperature immersion tin, are not resistant to high temperature, and have serious yellowing after reflow soldering. Contents of the invention [0003] The object of the present invention is to provide a liquid photosensitive solder resist white oil and its preparation method, which solves the problems of the existing traditional solder resist white oil turning yellow after high temperature, serious discoloration and the like. [0004] In order to achieve the above-mentioned design purpose, the technical scheme adopted in the present invention is as follows: [0005] A liquid photosensitive solder resist white oil is mainly composed of a main agent and a curing agent in a mass ratio of 4:1.
