Problems solved by technology

However, the problem of using screen printing is that there are many plates and a long process, and a large amount of waste ink will be generated during use, which will bring pressure to the environment.
[0004] However, there are still technical breakthroughs to be made by printing the anti-etching protective layer by inkjet

Abstract

The invention provides etching-resistant jet ink and provides a method for preparing a conductive circuit by using the etching-resistant jet ink. The etching-resistant jet ink comprises a photocuring monomer, an oligomer, a pigment and a photoinitiator, wherein the photocuring monomer comprises at least one of monofunctional (methyl) acrylate, bidirectional (methyl) acrylate and tri-functional acrylate; the bidirectional (methyl) acrylate comprises at least one of bidirectional (methyl) acrylate with a glycol structure or propylene glycol structure in the molecular structure. The etching-resistant jet ink is good in flowability, applicable to jet ink technique and good in stable jet printing property, a temporary protecting layer formed after the jet ink is cured can meet the process requirements of the circuit board in the production process and is resistant to corrosion of an etching liquid without dropping, and rapid stripping can be achieved in an alkali liquid after the etching process is completed.

Description

technical field [0001] The invention relates to an anti-etching ink-jet ink, which is mainly used in the etching stage of the circuit board manufacturing process to form a temporary protective layer to prepare circuits. Background technique [0002] The etching stage of the circuit board (PCB) is the process of making conductive lines. The usual method is to make a plate first, and then use ink to print the circuit pattern on the copper clad board by screen printing, and then form it through exposure, development and other processes. Temporary protective layer, the unprotected bare copper part is etched away in the etchant. After the etching is completed, the ink protective layer needs to be removed in lye to form a conductive line. However, the problem of using screen printing is that there are many plates and a long process, and a large amount of waste ink will be generated during use, which will bring pressure to the environment. [0003] Digital inkjet technology is a ...
