Technical Support: 199-6293-0018 In the modern electronics manufacturing field, Printed Circuit Boards (PCB) are the core for connecting electronic components, achieving electrical connections and signal transmission. However, the issue of PCB warping has always been a challenge in the manufacturing process, as it not only affects the physical integrity of the product but may also … Read more
To achieve high-density wiring, shorten signal transmission paths, and enhance signal integrity, the via in pad is introduced. However, the design of vias in pads presents challenges for soldering. Since the vias are located within the pads, some solder may flow into the vias during the soldering process, leading to insufficient solder on the pads, … Read more
The main purpose of PCB Surface Finish is to protect the underlying copper layer from oxidation to ensure good soldering and electrical conductivity, and to continuously protect the solder joints from further oxidation after soldering. Below is a brief introduction to the advantages and disadvantages of common PCB surface treatment processes. 1. Bare Copper Board … Read more
The switching node of a switching regulator or power converter circuit is a critical conduction path that requires special attention during PCB layout. This circuit node connects one or more power semiconductor switches (such as MOSFETs or diodes) to magnetic energy storage devices (such as inductors or transformer windings). Its switching signals contain rapidly switching … Read more

What Is Impedance? Isn’t It The Same As Resistance? Regarding impedance (Impedance), I have found that many newcomers to this concept often confuse it with resistance (Resistance). This confusion may arise because both terms contain the character for “resistance” in Chinese, and both units are expressed in Ω. Additionally, impedance and resistance are related to … Read more
