Introduction to ESP32 The ESP32 is a low-cost, low-power system on a chip (SoC) series with Wi-Fi & dual-mode Bluetooth capabilities. It is designed and developed by Espressif Systems, a Shanghai-based Chinese company. The ESP32 series employs a Tensilica Xtensa LX6 microprocessor in both dual-core and single-core variations and includes […]

What is a Ball Grid Array (BGA)? A Ball Grid Array (BGA) is a type of surface-mount packaging used for integrated circuits (ICs). It utilizes a grid of solder balls on the bottom side of the package to provide electrical connections between the IC and the printed circuit board (PCB). […]

Introduction to HDI PCBs High Density Interconnect (HDI) Printed Circuit Boards (PCBs) are a type of circuit board that offers higher wiring density than traditional PCBs. HDI PCBs have finer lines and spaces (<100 μm), smaller vias (<150 μm), and capture pads (<400 μm), and higher connection pad density (>20 […]

Introduction to PCB Fabrication Printed Circuit Board (PCB) fabrication is the process of creating printed circuit boards used in electronic devices. PCBs provide the physical structure and electrical connections for components like resistors, capacitors, and integrated circuits. The PCB fabrication process turns a design into a functional board ready for […]

Introduction to PCB materials Printed Circuit Boards (PCBs) are the backbone of modern electronics, providing a reliable and efficient means of connecting electronic components. The choice of materials used in PCB Fabrication plays a crucial role in determining the performance, durability, and cost of the final product. In this comprehensive […]

Introduction to Via Fill in PCB Design In the world of printed circuit board (PCB) design, vias play a crucial role in connecting different layers of the board. Vias are essentially small holes drilled through the PCB that allow electrical connections to be made between different layers. There are two […]

The Evolution of PCB Technology PCBs have come a long way since their invention in the early 20th century. The first PCBs were simple, single-sided boards with through-hole components. As electronics became more complex and miniaturized, PCBs evolved to accommodate these changes. The introduction of double-sided boards, multi-layer boards, and […]

Introduction to PCB Development and Emerging Trends Printed Circuit Boards (PCBs) are the backbone of modern electronics. These thin boards made of fiberglass or composite material provide mechanical support and electrical connections for electronic components using conductive pathways, tracks, or signal traces etched from copper sheets. PCBs have revolutionized the […]

What is a Regular PCB? A regular PCB, also known as a conventional PCB, is a printed circuit board that consists of conductive tracks, pads, and other features etched from copper sheets laminated onto a non-conductive substrate. These boards are used to mechanically support and electrically connect electronic components using […]

What is PCB Back Drilling? PCB back drilling, also known as controlled depth drilling or back-drill, is a process used in the manufacturing of high-speed printed circuit boards (PCBs) to remove the unused portion of a plated through-hole (PTH) that extends beyond the last layer of the PCB. This technique […]
