In the process of PCB manufacturing and soldering, the issue of solder balls or solder ball blockage in solder mask vias is a common yet troublesome problem. Solder balls not only affect the aesthetic quality of the product but can also lead to circuit shorts, severely impacting the reliability and lifespan of the product. Today, … Read more
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

PCB design is based on the circuit schematic to achieve the functions required by the circuit designer. This article summarizes several common issues in PCB circuit design for reference, hoping that engineers can continuously improve in their circuit designs, achieving excellent circuit performance and heat dissipation, effectively saving production costs. 1. Overlapping Pads 1. The … 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
