After the delivery of a previous design project, due to an operational error by the on-site debugging personnel, the exposed wire ends touched the circuit board (which was coated with a conformal coating) when the rear panel of the device was removed, ultimately causing a short circuit. The feedback from the site indicated that the … Read more
Today, someone in the group shouted that there was a power short circuit on the board, and they had almost removed all the components, yet the short circuit still persisted. This feeling of helplessness, exhaustion, and frustration resonates with many! Engineers working with hardware and those involved in manufacturing must have encountered this situation numerous … Read more
Today, we will not discuss PCB design. Everyone knows that “circuit short circuits” are problems that PCB manufacturers encounter almost daily, and they are relatively difficult to solve. The improvement of this issue directly relates to production costs and the qualification rate of finished products. The first step in improvement is inspection. Below, I will … Read more
Author: Snail of the Automotive Industry The ASC (Active Short Circuit) of motor controllers is a safety protection mechanism for motors. Working Principle: By simultaneously turning on the upper or lower three bridges of the IGBT, a closed loop is formed in the motor stator windings, thereby achieving active short circuit protection. Generally, there are … Read more
