Printed circuit board (PCB) layout may be considered an art form by circuit designers, and there is a lot of truth to that. Creating the most reliable, functional, and cost-effective circuits and finished PCBs can be a challenging task, especially with today’s demand for increasingly complex requirements for compact, lightweight, and even flexible circuit boards….
Abstract This paper examines the critical requirements for non-electrolytic nickel coatings on printed circuit boards (PCBs) in modern electronics manufacturing. As PCBs continue to evolve with higher density interconnects and more demanding operating conditions, the specifications for nickel surface finishes have become increasingly stringent. The discussion covers thickness requirements, adhesion standards, solderability, corrosion resistance, electrical…
Introduction to PCB Edge Conductivity Printed Circuit Board (PCB) edge conductivity, also known as edge plating or castellation, is a specialized technique used to create electrical connections along the perimeter of a PCB. This method serves multiple purposes in electronic design, from improving EMI shielding to enabling board-to-board connections in stacked configurations. Edge conductivity has…
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…
Promote the application technology exchange of PTH, polymer conductive film, electroplating, OSP and other related materials in the AC PCB process, and the experience of solving PCB process problems.

PCB layout engineers face thousands of lines on the board every day, various packages, and repeat the work of pulling wires. Many people may think that this is a very boring job. Although they seem to be software operators, designers actually have to make trade-offs between various design rules in the process, taking into account…
1. Introduction As human beings’ requirements for living environment continue to increase, the environmental issues involved in the current PCB production process are particularly prominent. At present, the topic of lead and bromine is the hottest; lead-free and halogen-free will affect the development of PCB in many ways. Although at present, the changes in the…
Abstract Copper pouring is a crucial aspect of printed circuit board (PCB) design, particularly in high-frequency and high-power applications such as switch-mode power supplies (SMPS), motor drivers, and DC-DC converters. Proper copper pour techniques enhance thermal management, reduce electromagnetic interference (EMI), and improve signal integrity. This paper explores the key considerations, methodologies, and best practices…
Introduction The performance, efficiency, and reliability of non-isolated switching power supplies are heavily dependent on their printed circuit board (PCB) layout. Unlike isolated converters, non-isolated topologies (such as buck, boost, and buck-boost converters) present unique challenges in PCB design due to their high-frequency switching currents and tight coupling between components. A well-executed PCB layout can…
Abstract Printed Circuit Board (PCB) manufacturing generates significant amounts of plating waste liquid containing heavy metals, acids, alkalis, and organic compounds. Improper disposal poses severe environmental and health risks. This paper explores various methods for the comprehensive utilization of PCB plating waste liquid, including metal recovery, chemical treatment, and resource recycling. By adopting these techniques,…
Introduction Printed Circuit Board (PCB) design for audio amplifiers requires meticulous attention to wiring precision to ensure optimal signal integrity, minimize noise, and maintain the amplifier’s performance characteristics. The quality of an amplifier’s sound reproduction is directly influenced by how effectively the PCB layout manages signal paths, power distribution, and grounding schemes. This article explores…
Introduction Printed Circuit Board (PCB) design plays a critical role in determining the quality, reliability, and manufacturability of electronic products. While much attention is often given to electrical performance and signal integrity, the soldering aspects of PCB design are equally important yet frequently overlooked. Proper consideration of soldering requirements during the design phase can significantly…
Introduction Printed Circuit Board (PCB) design has become increasingly complex as electronic devices demand higher speeds, greater functionality, and smaller form factors. Among the most critical aspects of PCB design is proper signal loop management, which directly impacts signal integrity, electromagnetic compatibility (EMC), and overall system performance. This article explores advanced techniques for mastering PCB…
Introduction Printed Circuit Board (PCB) design is a complex process that requires precision and attention to detail. One common issue that designers encounter is broken traces (or “cut traces”), also known as “dead traces” or “disconnected traces.” These occur when a conductive pathway on the PCB is unintentionally interrupted, leading to open circuits and malfunctioning…
Introduction Printed Circuit Boards (PCBs) are the backbone of modern electronics, providing the necessary electrical connections between components. The routing layers of a PCB play a critical role in ensuring signal integrity, power distribution, and overall functionality. However, poor routing practices can lead to significant manufacturability issues, affecting yield, reliability, and cost. This article explores…
