Abstract

The invention relates to a screen plate cleaning solution, which contains an alkali compound and a resin stripping agent, and has a pH value of 10-14. According to the present invention, through the reaction among the alkali compound, the resin stripping agent and the resin layer of the screen plate, the regenerated screen plate is prepared by using the screen plate cleaning solution of the present invention, such that the resin layer of the screen plate can be effectively removed, and the oxidation and dark reaction between the metal net of the screen plate can be effectively prevented so asto improve the yield and the quality of the screen printing.

Description

technical field

[0001] The invention relates to a cleaning liquid and a method for using the same, in particular to a screen cleaning liquid for printing and a method for using the same. Background technique

[0002] With the multiplexing and miniaturization of electronic devices, the circuit substrates of electronic devices must be equipped with high-density electronic components and wiring. Metal screen printing has been applied to the manufacturing process of these circuit substrates to meet the miniaturization of electronic components and distribution line requirements. The process of metal screen printing electronic circuits includes the following steps: first, coating a photosensitive emulsion (for example: acrylic resin) on the metal mesh cloth with warp and weft; second, exposing and developing the photosensitive emulsion to form a screen pattern (ie Photosensitive emulsion layer with miniaturized ink penetration holes after development); then, applying pressure to ...
