In the manufacturing process of electronic products, PCB and PCBA are two indispensable links. PCB is the carrier of electronic components, while PCBA is the finished product after the assembly of components on the PCB. Although closely related, there are many differences in various aspects. This article will detail these differences. 1. Differences in Structure … Read more
As a support for electronic components and a provider of electrical connections, printed circuit boards (PCBs) play a crucial role in the electronics industry. Based on different classification criteria, PCBs can be divided into various types. So, do you know what types of PCBs exist? What are their differences? 1. Structural Classification Single-sided board: The … Read more
Source: PCB Consulting A Detailed Analysis of PCB Manufacturing Processes with Illustrations. 1. Cutting (CUT) Cutting is the process of slicing the raw copper-clad board into boards that can be made on the production line. First, let’s understand a few concepts: (1) UNIT: A UNIT refers to the unit graphics designed by PCB design engineers. … Read more
There are two methods for manufacturing multilayer boards: the electroplated via method and the high-density lamination method, both of which achieve circuit board structures through different combinations of processes. Currently, the most commonly used method is the electroplated via method, which has developed and improved over more than half a century. In terms of equipment, … Read more
In integrated circuit application design, after completing the project schematic design, PCB layout design is necessary. PCB design is a crucial step. The quality of the design results directly affects the overall functionality of the design. Therefore, a reasonable and efficient PCB layout is essential for the successful debugging of chip circuit design. In this … Read more
With the increasing integration of semiconductors, major electronic systems now feature complete system-on-chip designs and custom PCBs. It can be said that even an ordinary PCB can play a significant role, which sets high standards for engineers. 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
