Description

technical field

[0001] The invention relates to a photosensitive ink, an electromagnetic shielding structure using the photosensitive ink, a circuit board and an electronic device, in particular to a conductive photosensitive ink and an electromagnetic shielding structure using the photosensitive ink, a circuit board and an electronic device. Background technique

[0002] In recent years, small and multi-functional electronic products are widely favored, which requires high-density integration of circuits and electronic components on flexible circuit boards for electronic product applications. Therefore, the requirements for electromagnetic shielding performance of flexible circuit boards are increasing. high.

[0003] There are two methods commonly used to avoid electromagnetic interference. One method is to use conductive cloth to make an electromagnetic shielding structure. The electromagnetic shielding structure includes an anisotropic conductive adhesive layer, a metal...
