Abstract: A rigid-flex printed circuit board module includes a non-working zone and a working zone. The non-working zone defines a receiving space. The working zone is disposed in the receiving space, and is connected to the non-working zone through a plurality of interconnecting zones. The interconnecting zones are flexible regions having greater flexibility than the non-working zone, and are of the same thickness and material. The interconnecting zones are defined by flexible circuit board member such that the interconnecting zones can be quickly cut off using a single machine during processing of the rigid-flex printed circuit board module. Thus, the speed of separating the working zone from the non-working zone can be increased, and costs and time associated with processing and manufacturing can be reduced. Additionally, the processing flow can be simplified, and the product quality of the working zone after cutting can be ensured.

Abstract: A molded fluorescent plastic lens and a manufacturing method thereof are disclosed. The fluorescent material 3 is attached on surface of plastic preform or a cavity of a mold core of a mold.
