Key Takeaways Stress during fabrication, such as thermal expansion and contraction, imbalanced copper distribution, and improper handling, can lead to warpage. Utilize tools like feeler gauges, height gauges, contour gauges, optical profilometers, and Finite Element Method (FEM) simulations to accurately measure PCB warpage. Effective design practices using OrCAD X, such as symmetrical component placement and...
A variable power supply PCB is one of the most essential designs in electronic engineering, lab equipment, industrial systems, and embedded development platforms. It allows adjustable output voltage and current, making it suitable for testing, prototyping, and powering sensitive circuits. Designing a reliable variable power supply PCB layout requires careful consideration of power integrity, thermal...
Key Takeaways The competitiveness of new product introduction makes it critical to optimize your prototype design process for effectiveness and efficiency. Your prototype PCB design software should exhibit essential attributes for managing component inventory, creating schematics, designing PCBs, verifying designs, and managing data. OrCAD X delivers the essential functionality and capabilities in one program for prototype design...
PCB design involves two critical stages: component layout and circuit connection wiring. The layout is the arrangement of circuit components within the PCB’s wiring area. A well-thought-out layout directly affects the ease of subsequent wiring and significantly impacts the PCB’s overall performance. In addition to meeting circuit functionality and performance requirements, a good layout considers manufacturability, inspection, and maintenance....
With the continuous development of smartphones toward higher performance, smaller size, and increased functionality, mobile phone PCB design has become more complex than ever. Modern smartphones integrate high-speed processors, RF communication modules, cameras, sensors, power management circuits, and high-density interconnect structures within extremely limited space. However, increasing circuit density and operating frequencies also introduce greater...
Printed Circuit Board (PCB) design is a critical step in the development of any electronic product. A well-designed PCB ensures reliability, performance, and manufacturability, while a poor design can lead to costly failures and delays. Below are five golden rules that every PCB designer should follow. 1. Prioritize Clear and Logical Layout A clean and...
Introduction: Addressing signal integrity (SI) issues early in the PCB design process can streamline the design and eliminate the need for corrective termination devices later. Here, we outline critical steps to maintain signal integrity, from planning through testing. 1. Preparation Before Design Begin by defining your SI requirements and design strategy. Early-stage planning will guide component selection,...
In PCB design, trace width is one of the fundamental parameters that directly affects the electrical performance, thermal reliability, and manufacturing quality of a circuit board. When current flows through a PCB trace, the conductor generates heat due to electrical resistance. If the trace width is insufficient, excessive temperature rise may cause: Copper trace overheating...
1. Should the dead copper be removed in PCB design? Some people say that it should be removed. The reasons are probably: 1. It will cause EMI problems. 2. Enhance the ability to engage in interference. 3. Dead copper is useless. Some people say that it should be kept. The reasons are probably: 1. Sometimes a...
In the world of power electronics, High-Voltage PCB design—typically involving circuits operating above 100V—presents unique challenges that go far beyond standard digital layouts. Designing for high voltage requires a deep understanding of dielectric breakdown, atmospheric conditions, and material science. Failing to implement proper high-voltage safety standards can lead to catastrophic arcing, board carbonization, or complete system failure. Whether...
