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 opened, ultimately causing a short circuit. The feedback from the site indicated that the … Read more

The sensor, as the first line of defense for measuring input, converts the measured variable into a measurable signal, which can be an analog signal, a digital signal, or other forms of … Read more
When checking for short circuits, open circuits, or leakage in a circuit, we usually use a digital multimeter or an analog multimeter for testing in actual repairs. However, the principles of digital and analog multimeters are different, so there are slight differences in checking with an analog multimeter and a digital multimeter. Below, we will … Read more
1. Introduction This is the test circuit board made for the STM32 microcontroller. The main purpose is to verify whether the software development tools are functioning normally in the newly installed computer. The microcontroller software can now be downloaded via probe clips. Below, using this test circuit board, we will perform a hazardous measurement. We … Read more
