1. Visual Inspection The first and most basic method of checking for soldering defects is visual inspection. This process involves carefully examining the soldered joints and components on the PCB Board using the naked eye or a magnifying glass. Some common defects that can be detected through visual inspection include: […]

1. Bridging What is Bridging? Bridging, also known as solder bridges, occurs when excess solder creates an unintended connection between two or more adjacent pads or traces on a PCB. This defect can lead to short circuits and cause the device to malfunction. Causes of Bridging Excessive solder paste application […]

What is a Waterproof PCB? A waterproof printed circuit board (PCB) is a specially designed and manufactured PCB that is resistant to moisture, water, and other liquids. Unlike traditional PCBs, which can be damaged or malfunction when exposed to water, waterproof PCBs are built to withstand wet environments and continue […]

Signal Integrity in High-speed PCB Design Signal integrity is a critical aspect of high-speed PCB design, as it directly impacts the quality and reliability of the transmitted signals. Poor signal integrity can lead to issues such as signal distortion, crosstalk, and reflections, which can compromise the performance of your design. […]

Introduction to Yocto Project The Yocto Project is an open-source collaboration project that provides templates, tools, and methods to help you create custom Linux-based systems for embedded products, regardless of the hardware architecture. It was founded in 2010 as a collaboration among many hardware manufacturers, open-source operating systems vendors, and […]

Introduction to ESD in SMT Assembly Electrostatic discharge (ESD) is a common phenomenon that can cause significant damage to electronic components during the surface mount technology (SMT) assembly process. ESD occurs when there is a sudden transfer of electrostatic charge between two objects with different electrical potentials. In the context […]

Introduction to the MT8870 The MT8870 is a DTMF receiver IC manufactured by various semiconductor companies, including Mitel, Zarlink, and others. It is designed to decode DTMF tones, which are the audible tones generated when pressing keys on a telephone keypad or other tone-generating devices. DTMF signaling is widely used […]
