Abstract
Description
technical field
[0001] The invention relates to a synchronous treatment method for stripping and anti-oxidation of copper-plated ITO of a capacitive touch screen sensor in a yellow light process. Background technique
[0002] During the yellow light process of the copper-plated ITO of the capacitive touch screen sensor, after the circuit pattern of the copper-plated ITO of the sensor is formed, the copper wire is exposed to the air and is easy to oxidize. In order to prolong the storage period, copper anti-oxidation protection must be used.
[0003] Under normal circumstances, in the last stripping process after the sensor circuit is formed, the stripping solution usually contains about 0.1% antioxidant, which can play an anti-oxidation effect, but the effect is minimal, and copper anti-oxidation is still required at the end. In addition, before the anti-oxidation process, it must go through complicated procedures such as degreasing and cleaning, which virtually increases th...
