Problems solved by technology

This method of bonding has the problem of unevenness. There are local gaps in the film and plastic bonding parts, which are easy to oxidize and the small molecules of the adhesive solvent are easy to volatilize in the air and cause pollution. It is easy to degumming after a long time.
In the production process, there are problems such as large labor costs, low production efficiency, high scrap rate, and high production costs.
Furthermore, the limitation of the internal space of a large number of micro-electrical appliances makes it very unlikely that the film printed circuit will be bonded to the plastic main part with double-sided adhesive tape.

Embodiment Construction

[0029] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further elaborated below in conjunction with specific illustrations.

[0030] refer to figure 1 , the manufacturing process of in-mold inserting injection molding circuit, comprising the following steps:

[0031] The first step is the manufacturing process of the printed circuit film, including: using nano-scale silver paste ink to screen-print on the matching 0.05-0.25 film to form a printed circuit, and a layer can be printed on the printed circuit according to different purposes. Insulating ink, forming an insulating layer. Hot-melt adhesive can also be printed on the insulating layer to form a layer of adhesive, which is used to bond with molten plastic under the high temperature conditions of injection molding.

[0032] The second step is the shaping process of the printed circuit film, including: according to ...

Abstract

The invention relates to the technical field of circuit printing technology, in particular to manufacture technology of a printing circuit. The manufacture technology of inlaying an injection circuit in a mold comprises the manufacture technology of a printing circuit film and further comprises film molding integration technology. The printing circuit film is embedded into a mold cavity of an injection mold and formed together with plastics in a molten state in an injection mode, and an integration injection part is manufactured. By the adoption of the technical scheme, the film and plastic gluing technology is once completed in an injection mold. The printed circuit film and a main molding part body are firmly integrated, and the manufacture technology of inlaying the injection circuit in the mold has the advantages that the printed circuit film does not desquamate and not to be oxidated without escaping of small solvent molecules and the like.

Description

technical field [0001] The invention relates to the technical field of circuit printing, in particular to a manufacturing process of a printed circuit. Background technique [0002] At present, the thin-film printed circuits used in the electronics industry are generally bonded with double-sided adhesive tape and plastic main parts. This method of bonding has the problem of unevenness. There are local gaps in the film and plastic bonding parts, which are easy to oxidize and the small molecules of the adhesive solvent are easy to volatilize in the air to cause pollution, and it is easy to degumming after a long time. In the production process, there are problems such as large labor cost, low production efficiency, high reject rate, and high production cost. Furthermore, the limitations of the internal space of a large number of micro-electrical appliances make it very unlikely that the thin-film printed circuit will be bonded to the plastic main part with double-sided adhesi...
