Background

At present, the common rigid-flex circuit boards are concentrated on 3-4 layers, wherein, the rigid-flex circuit boards with more than six layers of embedded inductance components are adopted by high-end intelligent equipment in the market. The trend toward smaller and smaller products, and the increasing amount of board surface space, is being strained, requires more power and higher currents to support more functions, higher speeds and lower voltages. There is also a need for significant improvements in power distribution systems. All this requires more passive devices. This is why the use of passive devices has increased at a higher rate than active devices. The benefit of placing the passive devices inside the circuit board is not only a space saving on the surface of the circuit board. The embedded mode eliminates welding points, and can reduce the impedance of a power supply system. Thus, embedded components save valuable board surface space, reduce board size and reduce weight and thickness. While reliability is also improved due to the elimination of solder joints, the embedding of passive devices will reduce the length of the wires and allow for a more compact device layout, thus improving electrical performance.

The embedded soft and hard combined board has various production processes, high production difficulty, extremely low yield, more materials and manpower, and particularly relates to a pressing process which relates to materials, pressing materials and process parameters of products, so that the pressing process is a key process for whether the embedded soft and hard combined board is successful or not.
