Description

Roll-to-roll capacitor product printing process

technical field

The invention relates to the field of electronics, in particular to a roll-to-roll capacitance product printing process.

Background technique

At present, when feeding capacitor products in the industry, the general process is to first cut the purchased substrate into sheets of different sizes, and then print non-conductive protective glue on the sheets, shrink them, and paste them dry. A series of processing processes such as film, exposure, development, etching, printing silver glue, etc. However, due to the feeding in the form of flakes, the production efficiency is low. At the same time, the effects of transshipment, environment, and machines during the production process will also cause scratches and scratches on the sheet material.

Contents of the invention

Based on this, it is necessary to provide a roll-to-roll capacitor product printing process that can improve production efficiency and reduce adverse effects caused by human influence.

A roll-to-roll capacitance product printing process includes the following steps: providing a base material, the base material includes a conductive surface and a non-conductive surface, and the base material is in a roll shape. Liquid ink is provided, and a printing machine is used to print the ink on the surface of the non-conductive surface of the substrate to form a protective layer. The conductive side of the substrate is then laminated roll-to-roll with a layer of dry film.

In one embodiment, the substrate is divided into a product area and a non-product area, and the size of the protective layer is larger than that of the product area on the non-conductive surface of the substrate.

In one embodiment, after the protective layer is formed by printing ink on the non-conductive surface of the substrate, a baking step is also performed.

In one embodiment, the baking is infrared baking.

In one embodiment, the baking temperature is 100°C.

In one of the embodiments, after laminating the dry film, the step of automatically cutting into sheets is performed.

In the roll-to-roll capacitance product printing process described above, a protective adhesive is directly pasted on the non-conductive surface of the roll substrate, and then a layer of dry film is laminated roll-to-roll on the conductive surface of the substrate. Work on the roll of the substrate to improve production efficiency, and at the same time avoid artificial abrasions, scratches, etc. during the production process.

The size of the protective glue is larger than the size of the non-conductive surface of the substrate. Fully protect the product area from being scratched. .

After the protective layer is formed on the non-conductive surface of the substrate, a baking step is also performed. The ink is converted from liquid to solid by baking. The baking is infrared baking. Preferably, the baking temperature is 100±5°C. At this baking temperature, the protective layer can be fully dried, and at the same time, it will not affect the baking of the dry film bonded to the conductive surface.

After pressing the dry film, the step of automatic cutting into sheets is carried out.

In the roll-to-roll capacitance product printing process described above, a protective layer is directly laminated on the non-conductive surface of the roll-shaped substrate, and then a layer of dry film is rolled-to-roll laminated on the conductive surface of the substrate. Work on the roll of the substrate to improve production efficiency, and at the same time avoid artificial abrasions, scratches, etc. during the production process.

The size of the protective layer is larger than the size of the non-conductive side of the substrate. Fully protect the product area from being scratched.

After the protective layer is pasted on the non-conductive surface of the substrate, a step of baking is also performed. The ink is converted from liquid to solid by baking. The baking is infrared baking. Preferably, the baking temperature is 100±5°C. At this baking temperature, the protective layer can be fully dried, and at the same time, it will not affect the baking of the dry film bonded to the conductive surface.
