Problems solved by technology

[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 the cost of equipment, labor costs and potion costs, and at the same time increases the number of defective products produced by manual operations between each process.

Embodiment

[0022] Embodiment: A method for synchronous treatment of stripping and anti-oxidation of copper-plated ITO of a capacitive touch screen sensor during the yellow light process, comprising the following steps:

[0023] a) In the liquid medicine adding tank, add the stripping solution by weight: copper antioxidant = 5 parts: 2 parts, then add 43 parts of pure water, and dilute it into a mixed liquid; after dilution, peel off the mixed liquid The concentration of sodium hydroxide in the membrane liquid is 2±0.5%wt, and the concentration of methanol in the copper antioxidant is 2±0.5%wt;

[0024] b) The above 100 parts by weight of the mixed drug solution is first heated to 30±5°C, and then 1 part by weight of an alkylsulfonate solution with a concentration of 10±5%wt is added to prepare a stripping antioxidant solution;

[0025] c) The product to be stripped, i.e., the copper-plated ITO is in the stripping process of the yellow light process. Synchronous treatment of peeling and ...

Abstract

The invention relates to a film removing and oxidization resisting synchronous processing method of copper plated ITO of a capacitive touch screen inductor in the yellow-light technology. The method includes the steps that film removing liquid and a copper oxidization resisting agent are added into a medicine and water adding groove, then purified water is added into the medicine and water adding groove, and mixed liquid medicine is formed after dilution; the mixed liquid medicine is heated, and then surface active agents are added into the liquid medicine to prepare film removing and oxidization resisting liquid; a product of which a film is to be removed is soaked into the film removing and oxidization resisting liquid to be subject to film removing and oxidization resisting synchronous processing. The film removing and oxidization resisting synchronous processing method of the copper plated ITO of the capacitive touch screen inductor in the yellow-light technology has the advantages of being simpler in technology, better in product yield, higher in production efficiency and lower in production cost.

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...
