Problems solved by technology

[0003] The silver electrode patterns produced by photolithography have neat edges, no burrs, and high-quality graphics, but the problem of disconnection is serious, and a large number of supplementary work is required to make up for the problem of disconnection, which increases the workload and reduces the performance of the entire board. lower yield

Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing:

[0020] figure 2 , 3 It is an explanatory diagram showing a method of double exposure of a photolithographic silver electrode according to the embodiment.

[0021] A negative photosensitive silver paste 2 is uniformly coated on a large area of ​​the entire glass substrate 1 and dried.

[0022] Cover the first mask 3-1 on the negative photosensitive silver layer for the first exposure, and the exposure time is set to t ( t min ≤ t 1 2 t max ) .

[0023] Use the second mask 3-2 to completely coincide with the position of the first exposure through strict registration and then perform the second exposure. The exposure time is still t ...

Abstract

This invention provides a method for processing plasma display board silver electrode in order to simply control electrode broken, applying negative photo silver paste photoetching process characterizing in applying two masks to cover the negative photo silver layer or to cover the negative photo sensitive silver layer in positive and negative to get it exposed.

Description

technical field [0001] The present invention relates to a method for producing silver electrodes of plasma display panels used for display devices and the like. Background technique [0002] The electrodes of the plasma display panel are strip-shaped conductive layers fabricated in parallel on the PDP substrate. Currently, low-cost silver electrodes are mainly used. In the PDP, the mainstream of the silver electrode fabrication method is photoetching negative photosensitive silver paste coating to form the silver electrode pattern. The traditional photolithography process such as figure 1 Shown: (1) uniformly coat the negative photosensitive silver paste on the PDP glass substrate, and dry it; (2) expose it with a mask made of electrode pattern; (3) develop; (4) ) fired. [0003] The silver electrode patterns produced by photolithography have neat edges, no burrs, and high-quality graphics, but the problem of disconnection is serious, and a large number of supplementary ...
