In PCB design, trace thickness and current carrying capacity are closely related factors that directly affect the reliability and performance of electronic systems. As electronic products continue moving toward higher power density, smaller form factors, and increased functionality, PCB traces must handle higher currents while maintaining acceptable temperature rise and electrical stability. Insufficient copper thickness...
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....
Sensors and transducers play integral roles in PCBs by enabling electronic systems to interact with and respond to the surrounding environment. Sensors detect physical parameters such as temperature, pressure, light, and motion, converting these analog signals into electrical signals that PCBs process. Sensors are used in various applications, from environmental monitoring and industrial automation to consumer electronics. By integrating...
With the growth of the semiconductor industry, the density of circuits within integrated circuits (ICs) has increased. Even with the increase in density, the number of input-output pins remains unchanged, which is one of the reasons for the increased complexity in IC packages. To ensure the reliability of ICs, IC testing is introduced at every stage of the production...
Introduction: Why High Temperature PCB Materials Matter In demanding electronic applications, high temperature PCBs are essential for ensuring stable performance, long-term reliability, and safe operation under extreme thermal conditions. Industries such as automotive electronics, aerospace systems, power electronics, and industrial automation require PCB materials that can withstand elevated temperatures without degradation. Choosing the right materials...
Why Manual PCB Soldering Quality Matters Although automated SMT PCB assembly is widely used in modern electronics manufacturing, manual PCB soldering remains essential for: Prototype PCB assembly Through-hole PCB assembly (THT) PCB rework and repair Low-volume electronics manufacturing Industrial and aerospace electronics maintenance However, improper manual soldering techniques can easily create PCB soldering defects, affecting:...
What Is Ball Grid Array (BGA) Technology? Ball Grid Array (BGA) is an advanced surface mount packaging technology widely used in modern electronic products requiring high pin counts, high-speed signal transmission, and compact PCB layouts. Unlike traditional leaded packages, BGA components use an array of solder balls located underneath the package to create electrical and...
Take a look at any type of multiconductor serial bus that uses single ended traces. You’ll probably see some resistors sitting around the bus being connected to driver pins and power or ground. The use of these resistors is intentional with the purpose being to set the signal level and reflection control on the bus....
Chip-Scale Package (CSP) is a type of integrated circuit packaging technology. The size of the package is up to 1.2 times the size of the actual die, with only a single-die and a direct surface mountable package. First originating in the 1990s, it was developed as a response to the demand for smaller and more efficient...
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...
