Description

Technical Field

[0001] The utility model relates to the technical field of pad plate jigs, in particular to a pad plate jig for improving ink cover holes of a packaging carrier plate. Background Art

[0002] A jig is a tool that is mainly used to assist in controlling position and operation. When printing ink directly on the FPC copper plate, the via faces the table and is not ventilated. The air in the hole cannot be discharged after printing, resulting in the ink being unable to cover the via. There is a risk of copper leakage at the hole ring. The silk screen table has a matrix-arranged vacuum adsorption. When the via on the board is exactly in the same position as the table air intake hole, the ink printed on the hole will be sucked onto the table, causing poor ink coverage. The jig does not have a precise positioning structure, resulting in inaccurate positioning, which affects the use effect. In view of this, in-depth research was conducted on the above-mentioned problems, resulting in this case. Utility Model Content

[0003] The purpose of the utility model is to provide a pad jig for improving the ink cover holes of a packaging carrier, so as to solve the problem that the existing pad jig for improving the ink cover holes of a packaging carrier proposed in the above background technology does not have a structure for improving poor ink cover holes and precise positioning.
