Abstract

The invention provides a flexible circuit board manufacturing process and a flexible circuit board. The manufacturing process comprises the steps of mixing a conductive material and a high-molecular material to obtain a mixture; forming a hollowed-out part on a substrate, wherein the hollowed-out part is consistent with a conductive circuit in shape; laying the mixture in the hollowed-out part; and carrying out high-temperature heating on the substrate laid with the mixture, and drying the mixture. According to the manufacturing process provided by the invention of the flexible circuit board, the whole manufacturing process does not involve a chemical corrosion process, so that it is necessary to adopt a chemical reagent, the whole manufacturing process is high in environmental protection degree and does not produce sewage. Meanwhile, compared with the traditional process in which corrosion is carried out after the conductive material is completely laid, the manufacturing process provided by the invention does not involve the waste of the conductive material, thereby being more cost saving.

Description

technical field [0001] The invention relates to the technical field of flexible circuit boards, in particular to a flexible circuit board manufacturing process and the flexible circuit board. Background technique [0002] Flexible circuit boards, also known as "soft boards", are printed circuits made of flexible insulating substrates. Flexible circuits provide excellent electrical performance, can meet the design needs of smaller and higher density mounting, and also help reduce assembly processes and enhance reliability. Up to now, flexible circuit boards are the only solution to meet the miniaturization and mobility requirements of electronic products. It can be bent, wound, and folded freely, and can withstand millions of dynamic bendings without damaging the wires. It can be arranged arbitrarily according to the spatial layout requirements, and can be moved and stretched in three-dimensional space, so as to achieve the integration of component assembly and wire connecti...
