Troubleshooting and testing are critical steps in ensuring the functionality and reliability of your PCB. This category covers the techniques and tools used for diagnosing and resolving issues in PCBs, including signal integrity problems, power supply noise, and common design flaws. Learn how to use logic analyzers, oscilloscopes, and other diagnostic tools to identify and fix problems in your PCB designs before they reach production.
The ESP32 is a low-power, low-cost, ultra-low-power system-on-chip microcontroller board developed by Espressif Systems. However, there are occasions when you may encounter difficulties in uploading your sketches to the board. This can be caused by several factors, such as incorrect
An oscilloscope is an essential tool for electrical engineers and hobbyists alike. It’s a powerful diagnostic device that can help you measure, visualize, and analyze waveforms, allowing you to quickly troubleshoot and debug your electronics projects. In this blog post,
What is PCB Crosstalk? PCB crosstalk is a voltage noise phenomenon caused by inductive coupling or capacitive coupling between two signal lines. Types of Crosstalk According to different sources, there are three different types of crosstalk on the PCB: inductive
Power Supply Noise is a kind of electromagnetic interference (EMI) from the power distributor system. the frequency spectrum of its conducted noise is about 10kHz~30MHz, up to 150MHz. This noise can interfere with the normal operation of electronic devices and
What is the Curve Tracer Testing? The curve tracer testing is a diagnostic tool used to measure the electrical performance of an electrical system. It measures inductance, resistance, and capacitance by measuring voltage and current in response to a range
Printed circuit boards (PCBs) are essential components of electronic devices, connecting all the parts together and allowing power to flow through the system. Despite their critical role, troubleshooting and resolving PCB problems can be a challenge. Fortunately, there are eight
Treadmill Motor Controller Introduction A treadmill motor controller is an electronic device that is used to control the operation of an electric motor on a treadmill. It functions by using a series of switches, potentiometers, and PCB electronic components to
