PCB warpage actually refers to the bending of the circuit board. It means that the originally flat circuit board will be slightly warped at both ends or in the middle when placed on the desktop. This phenomenon is called PCB warpage by industry insiders. The circuit board warpage calculation formula is to place the circuit…
Understand DIP DIP is a plug-in. The chip using this packaging method has two rows of pins, which can be directly soldered on a chip socket with a DIP structure or in a soldering position with the same number of solder holes. Its characteristics are that it can easily realize the perforation soldering of the…
The first thing involved in the EMC design of PCB is the layer setting; the number of layers of a single board is composed of the number of power supply layers, the number of ground layers and the number of signal layers; in the EMC design of the product, in addition to the selection of…
Introduction Printed Circuit Board (PCB) design represents one of the most critical aspects of electronic product development, where proper grounding techniques often distinguish between a functional circuit and one plagued with noise, interference, and reliability issues. Grounding in PCBs serves as the reference point for all voltages in the system, provides return paths for currents,…
Introduction Printed Circuit Board (PCB) design involves multiple critical steps, one of which is fanout design—the process of routing traces from component pads to vias or other layers. Proper fanout ensures signal integrity, thermal management, manufacturability, and electromagnetic compatibility (EMC). This guide explores PCB module fanout design principles, best practices, and common techniques to optimize…
Introduction Printed Circuit Board (PCB) routing is a critical phase in the design process, where electrical connections are established between components based on the schematic diagram. Proper routing ensures signal integrity, reduces electromagnetic interference (EMI), and enhances the overall performance and reliability of the PCB. This article explores the fundamental principles of PCB routing, covering…
Introduction to PCB Grounding Proper grounding is one of the most critical aspects of printed circuit board (PCB) design and functionality. Grounding provides a reference voltage level for all components on the board, serves as a return path for currents, and helps shield sensitive circuits from electromagnetic interference (EMI). When grounding is implemented incorrectly, it…
1. Introduction In the manufacturing and assembly of printed circuit boards (PCBs), mark points (also known as fiducial marks) play a critical role in ensuring precise component placement. These reference points enable automated assembly equipment, such as pick-and-place machines and optical inspection systems, to accurately align PCBs during production. Improperly designed or placed mark points…
Introduction Printed Circuit Board (PCB) design is a critical aspect of electronic product development, influencing both electrical performance and mechanical integrity. While much attention is given to signal integrity, thermal management, and electromagnetic compatibility (EMC), the mechanical constraints and structural requirements of PCB design are equally important. A well-designed PCB must fit seamlessly within its…
Introduction Printed Circuit Board (PCB) manufacturing relies heavily on precise imaging processes, where negative films play a critical role in pattern transfer. Negative film deformation represents one of the most persistent challenges in PCB production, potentially causing misalignment, short circuits, or open circuits in the final product. This technical paper examines the root causes of…
Introduction In an era where digital and physical worlds increasingly converge, traditional paper business cards are being reimagined through innovative technology. One of the most exciting developments in professional networking tools is the NFC-enabled PCB business card—a functional circuit board that combines the durability of printed circuit board (PCB) materials with the convenience of near-field…
Introduction Printed Circuit Board (PCB) stackup design and impedance calculation are critical aspects of modern electronic design, particularly for high-speed digital circuits and high-frequency analog applications. As signal speeds continue to increase and form factors shrink, proper stackup design and controlled impedance become essential for ensuring signal integrity, reducing electromagnetic interference (EMI), and maintaining overall…
In the design of PCB board, the anti-ESD design of PCB can be achieved through layering, proper layout, wiring and installation. In the design process, most design modifications can be limited to adding or reducing components through prediction. By adjusting the PCB layout and wiring, ESD can be well prevented. Static electricity from the human…
PCB (Printed Circuit Board), Chinese name for printed circuit board, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. Because it is made by electronic printing, it is called a “printed” circuit board. Function After electronic equipment uses printed…
PCB is like the skeleton and nerve network of electronic circuits, and plays a vital role in electronic engineering projects, but many people do not know or do not know enough about PCB design. In fact, there are many fun things in PCB design, and only by practicing can you have a deep understanding. When…
