FLEXIBLE PRINTED CIRCUIT AND MANUFACTURING METHOD THEREOF, ELECTRONIC DEVICE MODULE AND ELECTRONIC DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18094683 titled 'FLEXIBLE PRINTED CIRCUIT AND MANUFACTURING METHOD THEREOF, ELECTRONIC DEVICE MODULE AND ELECTRONIC DEVICE

Simplified Explanation

The patent application describes a flexible printed circuit and a method for manufacturing it, as well as an electronic device module and an electronic device that utilize this circuit. Here are the key points:

  • The flexible printed circuit consists of a main sub-circuit board and a bridge sub-circuit board.
  • The main sub-circuit board includes a first substrate with a first bridge end, a second bridge end, a first wiring portion, and a second wiring portion.
  • The first and second wiring portions are spaced apart and connected to the first and second bridge ends, respectively.
  • The bridge sub-circuit board includes a second substrate with a third bridge end, a fourth bridge end, and a third wiring portion for a first functional wiring line.
  • The third bridge end and fourth bridge end are connected by the third wiring portion.
  • The first and second substrates are not in direct contact, and the bridge sub-circuit board is mounted on the main sub-circuit board by connecting the third and fourth bridge ends to the first and second bridge ends.

Potential applications of this technology:

  • This flexible printed circuit can be used in various electronic devices, such as smartphones, tablets, wearables, and other portable devices.
  • It can also be applied in automotive electronics, medical devices, and industrial equipment.

Problems solved by this technology:

  • The wiring layout of the flexible printed circuit is simplified, making it easier and more efficient to manufacture.
  • The use of a bridge sub-circuit board allows for separate wiring and connection of different functional lines, improving flexibility and modularity in electronic device design.

Benefits of this technology:

  • Simplified manufacturing process reduces production time and cost.
  • Improved flexibility and modularity enable easier customization and upgrading of electronic devices.
  • The separate wiring and connection of functional lines enhance the overall reliability and performance of the electronic device module.
