STMicroelectronics’ STSPIN9P series of 75V motor-drive ICs accelerates development of robust industrial drives. Suited to operation from popular bus voltages such as 48V, the 12 STSPIN9P devices let ...
Abstract: The paper proposes PCB-DETR, a novel detection network for PCB surface defect identification, which enhances the performance of small defect detection through improvements to the ...
The printed circuit board assembly process has undergone revolutionary changes over the past three decades. What once relied ...
Forbes contributors publish independent expert analyses and insights. Technology journalist specializing in audio, computing and Apple Macs. FiiO is an audio brand with a wide range of portable and ...
To address the issues of missed detection and false detection during the defect inspection process of the PCB, an improved YOLOv7-based algorithm for PCB defect detection is proposed. Firstly, the ...
In most operational amplifier (op amp) circuits, the resistor tolerance and resistor temperature coefficient determine the gain accuracy and gain temperature drift (Figure 1 shows a typical circuit).
The input offset voltage (V OS) of an operational amplifier (op amp) is modeled as a DC error source that acts like a voltage source on the noninverting input. It can ...
Abstract: Carbon fiber reinforced composites (CFRCs) exhibit the characteristic of coupling resistance and damage; therefore, Electrical resistance tomography (ERT) can be used to image in-situ damage ...
