Developer with cleaning function

Abstract

This invention provides a developer with cleaning function, which combines developing and cleaning functions to effectively solve the problem of foam formation during the developing process, ensuring that the developer acts uniformly on the PCB surface. This improves developing efficiency, reduces developer usage and processing time, and lowers production costs. The developer of this invention comprises the following substances: polyethylene glycol, sodium alkylnaphthalene sulfonate, sodium dodecylbenzene sulfonate, potassium carbonate, and deionized water. Specifically, polyethylene glycol accounts for 0.1% to 0.5% by weight; sodium alkylnaphthalene sulfonate accounts for 0.1% to 0.5% by weight; sodium dodecylbenzene sulfonate accounts for 0.1% to 1% by weight; potassium carbonate accounts for 0.1% to 20% by weight; and deionized water accounts for 78% to 99.6% by weight. Furthermore, the above substances are mixed by stirring at room temperature. This invention rapidly inhibits foam formation during the developing process and quickly eliminates existing foam without affecting its ability to dissolve photoresist.
