Creating a robust component library is one of the most challenging yet critical aspects of PCB design. The quality of the library, which includes schematic symbols, PCB footprints, and 3D models, directly impacts the success of your board development. Among these, the PCB footprint plays a pivotal role in determining whether your board can be manufactured and...

The relationship between PCB trace thickness and current capacity is a critical aspect of PCB design. Properly sizing traces ensures that they can handle the required current without overheating, which is essential for the reliability and functionality of the circuit. This article explores the key considerations for selecting trace thickness, the impact of copper weight, and...

Printed Circuit Board (PCB) routing is a critical aspect of electronic design, ensuring that electrical signals are transmitted efficiently and reliably between components. Proper routing minimizes interference, maintains signal integrity, and meets design requirements such as impedance control and thermal management. This article outlines the best practices for PCB routing, focusing on optimizing performance and ensuring signal integrity....

Electronics are becoming faster, smaller, and used in more demanding environments. Miniaturized ICs and SMDs operate at higher frequencies and require more power. Increased current demands cause voltage drops across resistive elements, generating heat and leading to temperature rises and hotspots. Over half of electronic component failures now stem from heat-related stress. To develop high-quality circuit...

PCB resistors are designed to be mounted and soldered to printed circuit boards; they control current flow and divide voltages, among other things.  PCB resistors come in many shapes and sizes, but they’re all designed to fit easily into board layouts. They have two terminals that can be soldered to the conductive traces on the PCB so they...

1. Customer Background The customer is a globally leading manufacturer of communication equipment, specializing in the development and production of large-scale routers, switches, servers, and high-speed networking devices. As modern network communications demand increasingly high signal integrity, reliability, and thermal stability, the customer required an 36-layer PCB with low-loss material (S1000-2M) and advanced immersion gold plating to ensure stable signal transmission...

1. Background Overview With the growing demand for smart cities and industrial automation, air quality monitoring systems have become critical in factories, laboratories, smart buildings, and underground facilities. A European client developing a gas sensor module for air quality detection required a high-precision, low-power, and stable PCBA solution with strong anti-interference capability. KKPCB was selected to deliver a customized...
