Abstract: One example described herein includes a method for fabricating integrated circuit (IC) packages. The method includes fabricating a plurality of IC dies and providing a conductive metal material sheet. The method also includes laser-cutting the conductive metal material sheet to form a lead-frame sheet. The lead-frame sheet includes at least one of through-holes and three-dimensional locking features. The method further includes coupling the IC dies to the lead-frame sheet and coupling the lead-frame sheet and the IC dies to packaging material to form an IC package block comprising the IC packages.

Abstract: Provided is a circuit board and an electronic device thereof. The circuit board includes: a substrate; an insulating ink layer disposed on the substrate; a component disposed on a side of the insulating ink layer facing away from the substrate, where the component is electrically connected to the substrate through a window opening area on the substrate; and an encapsulation layer disposed on a side of the component facing away from the substrate. The insulating ink layer includes a first hydrochromic material, and in a case where humidity exceeds a first humidity threshold, the first hydrochromic material changes from a first color to a second color.

Abstract: The present invention discloses a sea fog monitoring method based on multi-source satellite remote sensing data. A fog and low cloud mixed region is preliminarily identified using visible light and infrared satellite remote sensing data. A temperature and humidity vertically-layered structure in the fog and low cloud mixed region is obtained using satellite microwave remote sensing data. Due to different heights of fog and low cloud high-humidity regions, the heights of the high-humidity regions can be extracted by a humidity layered structure, so that fog and low clouds are distinguished, and the monitoring accuracy of fog is effectively improved.
