This article summarizes the experiences of several experts and lists ten golden rules for PCB design, hoping to … Read more
1. Working Principle The working principle of a circuit board is to use an insulating material to separate the surface copper foil conductive layer, allowing current to flow along a pre-designed route through various components to perform functions such as work, amplification, attenuation, modulation, demodulation, and encoding. Figure 1: Circuit Board 2. Components The circuit … Read more
Click Blue Text Follow us~ Today, I share an experience summary on PCB process design, hoping to inspire industry colleagues. 1 PCB Basic Technology 1.1 PCB Size and Shape The welding processing dimensions of the PCB material shape are width (200mm～250mm) * length (250mm～300mm). For PCBs with a long edge less than 125mm or a … Read more
Whether engineers or PCB manufacturers, they inevitably encounter PCB failures. The occurrence of these failures may lead to delays in product delivery, damage to the manufacturer’s reputation, and increased time and monetary costs. (Most importantly, it costs money.) Today, we mainly discuss PCB failure modes and solutions. (It is recommended to save for later viewing, … Read more
Despite the increasing integration of semiconductors and the availability of off-the-shelf systems on chip for many applications, there are still many use cases where electronic products require custom PCBs. In one-time development, even a standard PCB can play a very important role. A PCB is the physical platform for design and the most flexible component … Read more
Many people studying electronics often encounter the technical terms Printed Circuit Board (PCB) and Integrated Circuit (IC), but they frequently confuse these two concepts and even misuse them in reports, leading to criticism. The root cause lies in insufficient understanding of PCBs and integrated circuits. Therefore, today we will clarify the differences between PCBs and … Read more
The diversity of PCBs in materials, layers, and processes caters to different electronic products and their specific needs, resulting in a wide classification. Below, we summarize some common differentiation methods to briefly introduce the classification of PCBs and their manufacturing processes. Let’s analyze it from three aspects. Materials Organic Materials ① Phenolic Resin: Phenolic resin, … Read more
Today, we will discuss the key points to consider when designing a PCB from a soldering perspective. 1. Factors Affecting PCB Soldering Quality From PCB design to the completion of soldering all components, achieving a high-quality circuit board requires the control of various aspects including PCB engineers, soldering processes, and soldering workers. The main influencing … Read more
PCB Printed Circuit Board Main Points 01 What is PCB? PCB (Printed Circuit Board) refers to a printed board that forms connections between points and prints components on a common substrate according to a predetermined design. It serves as a support for electronic components and as a carrier for their electrical interconnections. Classification 1. According … Read more
