Problems solved by technology

[0006] Aiming at the problem that the ultra-thin copper layer will produce wrinkles during the processing of the existing ultra-thin flexible board, which will affect the production of the circuit and cause the problem that the yield rate of the product is very low
The invention proposes an improved processing technology optimization method for ultra-thin flexible boards, that is, the method of tearing off the protective copper after processing black holes, and using laser drilling instead of mechanical drilling to solve the problem of carbon in black holes. The problem of powder remaining on the surface of copper foil has been solved, and the processing technology has been optimized

Description

technical field [0001] The invention belongs to the technical field of ultra-thin flexible board processing, and in particular relates to a method for optimizing the processing technology of ultra-thin flexible boards. Background technique [0002] Flexible printed circuit board (Flexible Printed Circuit Board, referred to as FPC) is a printed circuit board made of flexible insulating substrates (mainly polyimide or polyester film), which has many advantages that rigid printed circuit boards do not have. For example, it can be bent, rolled, and folded freely. The use of FPC can greatly reduce the volume of electronic products, which is suitable for the development of electronic products in the direction of high density, miniaturization and high reliability. Therefore, FPC has been widely used in aerospace, military, mobile communications, laptop computers, computer peripherals, PDA, digital cameras and other fields or products. [0003] Medical FPC products have their uniq...
