PCB edge plating is a process that involves coating or plating conductive materials (usually copper) on the sides of the PCB along its height. Typically, ENIG surface treatment is used for plating at Jiepei. The purpose of edge plating is twofold. First, it provides reliable electrical connections. When the edge of the PCB needs to … Read more
Today, let’s discuss the color differences in PCB materials. Various types of boards produced by different manufacturers often exhibit subtle differences in color. These differences are not only related to the properties of the materials but may also reflect variations in their production processes and application fields. Differences in Color of Different Types of Boards … Read more
Silkscreen design is an essential factor in PCB design. The silkscreen on a PCB typically includes: component silkscreen and designators, board name, version number, anti-static symbols, barcode silkscreen, company logo, and other identifiers. Next, let’s take a look at the requirements for silkscreen design in PCB design. 1. Silkscreen Design Requirements The height-to-width ratio of … Read more
PCB Circuit Advanced Schematic Design The advanced design of PCB schematics requires integration of engineering practices, signal integrity, design specifications, and advanced tool functionalities. 1.Modular and Hierarchical Design Modular Segmentation: Divide complex circuits into independent modules based on functionality (such as power supply, MCU, communication interfaces) for easier reuse and maintenance. Hierarchical Schematics: Use hierarchical … Read more
Recently, a long-time friend reached out to me on social media, expressing a hint of helplessness: “Do you have any PCB design work available? I want to take on some side jobs on weekends to supplement my household income.” This friend has been in the electronics industry for many years. Although he is in a … Read more

When the PCB returns to the red horizontal line above, it marks the true start of the market trend. The return process is also the process of a second pullback. Will the second pullback bottom out at 3220 points or 3180? It depends on where the PCB lands when it returns to the red horizontal … Read more
Introduction: In the previous article, we introduced the manufacturing process of PCBs, but we would like to delve deeper into the aspects of via copper thickness and the aspect ratio of PCB vias. Definition of PCB Copper Thickness The thickness of copper in a circuit is measured in ounces (oz). So, why is thickness expressed … Read more
