Abstract: A flexible printed circuit includes a first connection end, a second connection end, and at least one cable arranged between the first connection end and the second connection end based on a target layout. The at least one cable connects the first connection end and the second connection to transmit signals, and each include a signal line and a base structure including a first base structure corresponding to a first part of the signal line and a second base structure corresponding to a second part of the signal line. The first part and the second part are two different parts of the signal line.

Abstract: A manufacturing method for low-magnetostrictive oriented silicon steel is provided, wherein the oriented silicon steel comprises a silicon steel substrate and an insulating coating on the surface of the silicon steel substrate. The manufacturing method comprises: performing single-sided laser etching on the silicon steel substrate, wherein the side of the silicon steel substrate, on which single-sided laser etching is performed, is a first surface, and the side opposite to the first surface is a second surface; determining a deflection difference between the first surface and the second surface based on the power of the laser etching, and determining a difference in the amount of the insulating coatings on the first surface and the second surface based on the deflection difference; and forming insulating coatings on the first surface and the second surface.
