Technical Field

The invention relates to the field of PCB manufacturing, in particular to a method and a system for manufacturing a rigid-flex printing plate.

Background

Rigid-flex boards are composed of rigid and flexible substrates that are selectively laminated together. The layers are conductively connected by metallized holes, and one or more soft regions are exposed on each layer. The rigid-flex printing plate can realize bending and three-dimensional installation, can effectively utilize the installation space and has high reliability. The rigid-flex combined mode can replace a press plug-in unit, and high reliability of the PCB under vibration impact, humid and severe environments is guaranteed.

With the development of the rigid-flex board, the number of layers of the board is more and more; the rigid plate has a multi-layer design, the flexible plate also has a multi-layer design, and the multi-layer flexible plate with a plurality of core plates laminated together at the inner layer is conventionally designed into a layer-by-layer design, namely, each flexible core plate of the multi-layer flexible plate is laminated with another flexible core plate without adopting an adhesive. However, the manufacturing method cannot meet the designed multilayer flexible plate with impedance requirement; and if the flexible core plates are separated, signal shielding between the multilayer flexible plates of the inner layer cannot be realized, and signal transmission is influenced.
