PCB Processing The precise dimensions required for millimeter-wave circuits demand well-controlled PCB processing techniques to produce circuits with consistently excellent performance. Variations in copper plating thickness and final surface treatment on the conductor surface can impact the performance of millimeter-wave circuits. To ensure the successful fabrication of high-performance millimeter-wave circuits, both of these processes must […]
From anti-collision radar systems used in autonomous vehicles to the fifth-generation (5G) high data rate New Radio (NR) networks, the application of millimeter-wave (mmWave) circuits is growing rapidly. Many applications are pushing the operating frequency bands to higher frequencies (such as >24GHz).
A Hybrid Printed Circuit Board (PCB) is a multilayer PCB that combines dissimilar materials to optimize electrical performance, improve system reliability, and enhance high-frequency RF applications.
Rogers Corporation is a leading manufacturer of advanced materials used in high-frequency PCB applications, particularly those that require excellent electrical and mechanical performance. Their copper foils are essential components in high-performance PCBs, especially in high-frequency and high-speed designs. Rogers’ copper foils are designed to maintain signal integrity and offer superior performance in applications where conventional copper may not be ideal.
Flexible printed circuit boards (PCBs) are a cornerstone of modern electronics, found in devices like smartphones, cameras, and electric vehicles. Unlike traditional rigid PCBs made from FR4 (flame retardant material), flexible PCBs utilize polymer substrates such as polyimide, resulting in their signature amber or orange appearance
Motor driver ICs handle high currents and dissipate substantial heat, so efficient PCB design is essential to ensure proper heat dissipation and reliable performance. Below are some best practices for designing a robust PCB for motor driver ICs.
Flexible PCBs (printed circuit boards) provide the ability to bend and conform to various shapes, making them an essential technology for space-constrained and dynamic applications. A 2-layer flex PCB contains a flexible dielectric layer sandwiched between two conductive copper layers. Designing these PCBs requires unique considerations, including material selection, layout techniques, manufacturability, and reliability.
Flexible printed circuit boards (flexible PCBs or flex circuits) are made from flexible insulating materials such as polyimide film. Unlike traditional rigid PCBs, flexible PCBs can bend and twist while maintaining electrical connectivity, making them ideal for space-constrained and dynamic applications.
Surface mount technology is a method of assembling electronic components onto a printed circuit board (PCB). Unlike traditional through-hole technology, where the leads of the component are inserted through holes in the PCB, SMT involves mounting the component directly onto the surface of the PCB. SMT offers advantages such as smaller size, higher manufacturing efficiency, and compatibility with automated assembly processes.
The application of solder paste is one of the most crucial processes in the SMT assembly. This process requires careful attention and a high level of precision. This is because the main goal is to apply solder in the proper location and adequately. Therefore, it is important to carefully coat each pad using the appropriate amount of solder.
