A method for identifying screen printing screens

Abstract

The invention discloses an identification method of a silk screen plate. The identification method comprises the following steps: (1) one set of digital identification plates similar to the shapes of digits 0-9 is manufactured; and the frontal surfaces of all the digital identification plates are provided with grooves with corresponding shapes; (2) each digital identification plate is bonded on acrylic adhesive; and during bonding, the frontal surfaces of all the digital identification plates are outwards to form tools similar to seals; (3) the corresponding digital identification plates are selected as needed to put in a barrel with net sealing slurry to dip into the net sealing slurry; and (4) the digital identification plates dip with the net sealing slurry in the step (3) cover the edges of the silk screen plate after taking out so as to leave corresponding digits as identification subareas on the edges of the silk screen plate. The method directly covers the prefabricated digital identification plates on digital marks on the silk screen plate after dipping of the net sealing slurry, can overcome the problems of easy label damage and falling and inconvenience for searching in the prior art, and can wash off the digital marks by water when replacing the silk screen plate with a different model number.

Description

technical field [0001] The invention belongs to the technical field of printed circuit board production, and in particular relates to a marking method of a screen printing screen. Background technique [0002] In printed circuit boards, solder resist inks and character inks are screen printing screens, which are printed onto circuit boards by manual or automatic screen printing machines. Because different types of circuit boards have different designs, the screen printing screens used are usually They are also different, and in order to save costs, many screen printing screens are reused several times. Therefore, how to distinguish the screen printing screen logos in a simple and practical way has become a problem that must be solved. [0003] In the prior art, the conventional method is to use a self-adhesive label, write the model, production date, version number and other information on the screen printing screen, and the defects of this method mainly include: [0004] 1...
