The present invention provides a fan-out package structure and a method for manufacturing the same. The fan-out package structure includes at least one chip and at least one redistribution layer on a functional surface side of the chip, and the redistribution layer includes a dielectric layer and a metal wiring layer distributed within the dielectric layer. The fan-out package structure further includes at least one dummy wafer on the redistribution layer, and the dummy wafer is insulated from the chip and in contact with the metal wiring layer. By providing the dummy wafer on the redistribution layer and configuring the dummy wafer to connect to the metal wiring layer, the dummy wafer can not only function to support the structure and suppress the warpage, but also form a continuous heat dissipation channel, thereby improving thermal management capability of the fan-out package structure.

Fan-out package structure and method for manufacturing the same

A detachable split solar power optimization junction box module has split junction boxes (A,B,C) each having a base part and an upper cover part. String ports () are provided in a base () of the base part for electrically connecting a string of a photovoltaic module (). The upper cover part has an upper cover () with a circuit board () provided therein. The circuit board () has a power optimization module connected with electrical connection pieces (). The electrical connection pieces () are detachably inserted into the string ports () so that the power optimization module performs power optimization on the string of the photovoltaic module. The split junction boxes (A,B,C) are used for power optimization at the string level. The power optimization module is integrated in the upper cover part that detachably connects with the base part for convenience of installation and maintenance.

Detachable split solar power optimization junction box module

A functionally integrated detachable photovoltaic module junction box has a base part and an upper cover part. The base part has string ports and two power supply ports. The string port electrically connects to strings on a photovoltaic module. The upper cover part has a circuit board therein. The circuit board has an optimizing and monitoring circuit and multiple electrical connection pieces connected to the optimizing and monitoring circuit. The electrical connection pieces are detachably connected to the string ports and the power supply port on the base part, for the optimizing and monitoring circuit to perform such functions as component optimization, monitoring, communication and shutdown on the photovoltaic module. Use of the junction box reduces the production, assembly and maintenance costs. When the junction box requires maintenance, only the upper cover part is needed to be replaced, thereby quickly completing the repair.
