Introduction to PCB Microsections PCB microsections are a crucial technique used in the analysis and quality control of printed circuit boards (PCBs). This process involves cutting a small, representative sample of a PCB and examining it under a microscope to assess the quality of the board’s construction, identify potential defects, […]

What is Selective Soldering? Selective soldering, also known as Selsoldering, is a process used in electronics manufacturing to solder specific components onto printed circuit boards (PCBs). Unlike wave soldering, which solders all components simultaneously, selective soldering targets individual components or groups of components, allowing for greater precision and flexibility in […]

Introduction to IPC-A-600 Standards IPC-A-600 is the industry standard for establishing acceptability requirements for printed circuit boards (PCBs). Developed by the Association Connecting Electronics Industries (IPC), this standard provides visual quality acceptability requirements and illustrations for PCBs. It covers various aspects of PCB manufacturing, including materials, workmanship, solderability, and surface […]

Introduction to ASU PCB ASU PCB, or Advanced Substrate Unicorn Printed Circuit Board, is a cutting-edge technology that has revolutionized the electronics industry in China. This innovative PCB design offers superior performance, reliability, and cost-effectiveness compared to traditional PCB technologies. In this article, we will explore the various aspects of […]

What are Blind-Buried-Vias? Blind and buried vias are two types of interconnects used in printed circuit board (PCB) design. These vias provide electrical connections between different layers of a multi-layer PCB, allowing for more complex and compact designs. Unlike through-hole vias, which span the entire thickness of the board, blind […]

What is Surface-mount technology (SMT)? Surface-mount technology is a method of assembling electronic components directly onto the surface of a printed circuit board. Unlike through-hole technology (THT), where component leads are inserted into holes drilled in the PCB and soldered on the opposite side, SMT components are placed and soldered […]

Introduction to Solder Paste Solder paste is a crucial component in the electronics assembly process, especially for Surface-mount technology (SMT). It is a mixture of tiny solder particles suspended in a flux medium, which helps to establish electrical and mechanical connections between electronic components and printed circuit boards (PCBs). Choosing […]

What is PCB Assembly? PCB assembly is the process of assembling electronic components onto a printed circuit board (PCB) to create a functional electronic device. The PCB is a flat board made of insulating materials, such as fiberglass or plastic, with conductive pathways etched onto its surface. These pathways, known […]
