Disclosed are a molded circuit board and a camera module, and a manufacturing method thereof and an electronic device comprising the same. The molded circuit board includes a circuit board main body and a molded structure. The circuit board main body includes at least one circuit layer and at least one substrate layer, wherein the circuit layer and the substrate layer are stacked in a manner of being spaced apart. The molded structure includes a molded layer, wherein the molded layer is stacked on at least one surface of the circuit board main body to cover at least part of the substrate.

Molded circuit board and camera module, and manufacturing method thereof and electronic device

The present application relates to a photosensitive assembly, a camera module and manufacturing methods therefor. The photosensitive assembly comprises a circuit board, a photosensitive chip electrically connected to the circuit board, at least one electronic component disposed on the circuit board, and a molded body integrally formed on the circuit board. The molded body has at least one slot formed therein in a recessed manner, and the slot is located outside the photosensitive chip. In this way, the magnitude of stress that the molded body acts on the photosensitive chip is reduced by means of the slot being disposed in the molded body, so as to effectively reduce the amount of deformation of the photosensitive chip due to the stress.

Photosensitive assembly, camera module and manufacturing methods therefor

A surface-mounted high-speed permanent magnet synchronous rotor includes a rotor shaft, multiple permanent magnet sets, multiple silicon steel piece sets and a rotor iron core sleeve. The multiple permanent magnet sets and the multiple silicon steel piece sets are glued on a surface of the rotor shaft along an axis of the rotor shaft. The multiple permanent magnet sets and the multiple silicon steel piece sets are spaced around the rotor shaft. The multiple permanent magnet sets have a same outer diameter as the multiple silicon steel piece sets, and the multiple permanent magnet sets and the multiple silicon steel piece sets are sleeved with the rotor iron core sleeve.
