Problems solved by technology
[0003] Flexible circuit boards, also known as "soft boards", are printed circuits made of flexible insulating substrates. Flexible circuits provide excellent electrical properties, can meet the design needs of smaller and higher-density installations, and also help reduce assembly processes And enhance the reliability, the flexible circuit board is the only solution to meet the miniaturization and mobile requirements of electronic products. At present, many flexible circuit boards generally connect the connection terminals of the electronic components with the terminal parts formed on the conductive layer, and then connect the Electronic components are packaged, but the stability of the electronic components of this flexible circuit board is poor, and the connection terminals are prone to breakage. The effect of the product

The invention provides a flexible printed circuit board and a manufacturing method thereof, and relates to the technical field of printed circuit board production. The flexible printed circuit board includes a film insulating substrate, an adhesive layer is provided on the upper surface of the film insulating substrate, a conductive layer is provided on the upper surface of the adhesive layer, and a terminal is provided on the upper surface of the conductive layer. Formation layer and solder resist layer, an installation hole is opened in the middle of the film insulation base material and the adhesive layer, an insulating sheet is connected to the inner wall of the installation hole, and the inside of the installation hole is located below the insulating sheet There are electronic components electrically connected with connection terminals. In the present invention, the electronic components are more stable inside the mounting holes through the insulating thin plates and insulating strips, which effectively reduces the breakage of the electronic components and connecting terminals, thereby making the flexible printed circuit board more stable during use. To a certain extent, the service life of the flexible printed circuit board is extended.
Description
technical field [0001] The invention relates to the technical field of printed circuit board production, in particular to a flexible printed circuit board and a manufacturing method thereof. Background technique [0002] Printed circuit boards, also known as printed circuit boards, referred to as printed boards, use insulating boards as the base material, cut to a certain size, have at least one conductive pattern attached to them, and are equipped with holes (such as component holes, fastening holes, metallization holes, etc.) Holes, etc.), used to replace the chassis of the previous installation of electronic components, and to realize the interconnection between electronic components. Since such boards are made using electronic printing, they are called "printed" circuit boards. [0003] Flexible circuit boards, also known as "soft boards", are printed circuits made of flexible insulating substrates. Flexible circuits provide excellent electrical properties, can meet the...
