About FPC hollow board

FPC hollowed-out circuit board, also known as window circuit board, FPC hollowed-out board, flexible hollowed-out board ect. Hollowed-out FPC board is made by punching, etching, lithography and other process methods. 

It is a product of flexible printed circuit board, and is a highly reliable and excellent flexible printed circuit board made of polyimide or polyester film and other basic materials. FPC hollow plate has several obvious characteristics, high wiring density, thin thickness, light weight, good bending. 

FPC hollow board is widely used in mobile phones, computer and LCD screens, CD listening and other products. Of course, while there are advantages, the FPC hollow plate itself also has some shortcomings. Firstly, its production process is complex, involving many process steps, which means that the production time is long. Secondly, with the development of electronic technology, especially in the context of the wide application of large-scale integrated circuits, fine lines appear in the direction of high-speed, high-precision and high-number changes of the FPC hollow plate with high density.

The through hole of flexible printed circuit board can also be drilled by numerical control as rigid printed circuit board, but it is not suitable for the hole processing of coil double-sided metallized hole circuit. With the high density of circuit graphics and the small aperture of metallized holes, and the aperture of CNC drilling has certain boundaries, many new drilling technologies have been put into practical application. These new drilling technologies include plasma etching, laser drilling, punching with small aperture, chemical etching, etc. These drilling technologies are easier to meet the drilling requirements of tape rolling process than CNC drilling.

Advantages and disadvantages of FPC hollow board 

FPC hollow circuit board is a product of flexible circuit board, which is made of polyimide or polyester film and other basic materials. It has high reliability and excellent flexibility. FPC hollow plate has several obvious characteristics, high wiring density, thin thickness, light weight, good bending.

Although there are some shortcomings, the practical and cost-effective FPC hollow board still has a broad market. With the innovation of science and technology, its thickness will become thinner and more flexible. In terms of bending resistance, can withstand more and more bending times ; price will also be accompanied by processing innovation and more affordable ; the upgraded process level will meet more requirements. The future FPC hollow plate will be presented in a better state in front of people.
