Basic soldering guide on how to solder electronic components to a printed circuit board (PCB). This is a detailed and complete soldering guide for both automated soldering in mass production and manual soldering in PCB rework and repair. How to Solder Electronic Components – Introduction Soldering is basically a technique of joining two metals using a...

At the heart of nearly every electronic product today is a printed circuit board (PCB), which supports and electrically connects the electronic components needed for an electronic device to function. Manufacturing a printed circuit board is a complex process that involves many steps that are different for every project. First, you need to design the board...

RO4000® hydrocarbon ceramic laminates are designed to off er superior high frequency performance and low cost circuit fabrication. The result is a low loss material which can be fabricated using standard epoxy/glass (FR-4) processes off ered at competitive prices. The selection of laminates typically available to designers is signifi cantly reduced once operational frequencies increase...

Printed Circuit Boards (PCBs) are a fundamental component in electrical engineering. They are used to create electronic circuits by arranging components such as transistors and resistors on a copper-based wiring pattern on the surface of an insulator (typically plastic) and then soldering them. PCBs are integral to nearly all electronic devices, providing the necessary pathways for...

Key Points of Millimeter-Wave Applications—Phase Accuracy Affected by Multiple Variables 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). However, for circuits with shorter...

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 be carefully controlled. For...

As high-density interconnect (HDI) designs with larger layer counts become more prevalent, the use of microvias is increasing. In builds with 3+N+3 or larger configurations, sequential lamination now often relies on skipped vias, staggered microvias, and stacked microvias. However, one of the key challenges is that microvias are more susceptible to failure than plated through-holes. The small...

When designing a printed circuit board (PCB), engineers often focus on ensuring the correct impedance structures and electrical performance of the board. However, the physical characteristics, such as PCB thickness, are equally important and can significantly impact the cost, manufacturability, and performance of the final product. While standard PCB thicknesses are widely used, they are more of a...

Designing double-sided PCBs requires careful planning to ensure efficient assembly, high yields, and reliable solder joints. Solder paste application and stencil design play a critical role in achieving these goals. This article explores key considerations for solder paste and stencil design, focusing on double-sided PCBs, component orientation, and advanced techniques for fine-pitch devices. Key Considerations for Double-Sided...
