1. What Do PCB Colors Represent? The color of a PCB generally refers to the color of the solder mask that is most visually apparent when you receive a PCB board. The color of the PCB surface is the color of the solder mask. The dye used for PCB boards is a type of hardened … Read more
In everyday life, we find that many PCBs in electronic products or devices are green. Do you know why? I believe there are several main reasons: 1. History and Tradition (The Core Reason) Military Origins: In the early stages of PCB development (mid-20th century), the U.S. military was the largest user and standard setter for … Read more
1. Check User Files The files brought by the user must first undergo routine checks: 1. Check if the disk files are intact; 2. Check if the file is infected with a virus; if there is a virus, it must be removed first; 3. If it is a Gerber file, check if there is a … Read more
Solder Mask: solder mask refers to the part of the board that is to be coated with green oil; because it is a negative output, the part that actually has the solder mask does not get green oil but is instead coated with tin, appearing silver-white!Paste Mask: paste mask is used during machine placement and … Read more
Solder Mask Layer The solder mask refers to the areas on the board where green oil is applied; since it is a negative output, the areas with solder mask actually do not have green oil but are instead coated with tin, appearing silver-white! Paste Mask Layer The paste mask is used during machine placement and … Read more
Definition of PCB Layers: Solder mask layer: solder mask, refers to the part of the board where green oil is applied; since it is a negative output, the part with solder mask actually does not have green oil but is plated with tin, appearing silver-white! Paste mask layer: paste mask, is used during machine placement, … Read more

1. Concept of PCBPCB (Printed Circuit Board), known in Chinese as 印制电路板, is an important electronic component that serves as a support for electronic components and provides electrical connections between them. It is called a “printed” circuit board because it is made using electronic printing technology.2. Role and Function of PCB in Various Electronic Devices1. … Read more
This article will explain the composition of PCBs in detail, as well as some commonly used terms in the PCB field, a brief assembly method, and an overview of the PCB design process. 01Birth of PCBBefore the advent of PCBs, circuits were composed of point-to-point wiring, which had low reliability. As circuits aged, wire breakage … Read more
