Introduction – Understanding Round PCBs In modern electronic product design, PCBs (Printed Circuit Boards) have evolved from their original simple rectangular form to encompass a variety of shapes and structures.

Electroplating via filling is a key technology in the field of modern high-density electronic packaging. It not only greatly enhances the design flexibility and performance of PCB boards, but also

RF pcbs are core components in electronic devices, and their performance stability directly affects the overall operational effectiveness of the device. However, in complex electromagnetic environments, RF circuit boards are

IntroductionAs electronic devices increasingly move toward higher density, higher performance, and smaller form factors, the manufacturing requirements for printed circuit boards (PCBs) are also increasing. As the foundation of electronic

What is a PCB teardrop? A PCB teardrop is an additional copper pad, either straight or circular, located at the connection point between a pad or via and a trace,

EMI coating is a thin film made from materials that shield electromagnetic interference signals, capable of blocking the propagation of electromagnetic waves. EMI coating is typically made from conductive materials

A graphics card circuit board, also known as a graphics card motherboard or graphics card PCB, is a circuit board used to transmit signals from the graphics processing unit (GPU).

On a graphics card pcb, the power supply section is just as critical as the graphics processing unit (GPU). If the GPU is the ‘brain’ of the graphics card, then

Definition and Function of Solder Mask Material in PCB Design In the printed circuit board (PCB) manufacturing process, solder mask is a crucial protective coating. It’s typically green, hence the

What is coverlay in fpc?FPC coverlay is polymer film made from materials such as polyimide (PI), primarily used to protect and insulate the external circuits of flexible PCB. FPC coverlay

PCB overmolding is a technique that involves coating printed circuit boards (PCBs) with protective polymer resin. This process is designed to protect PCBs from external factors such as humidity, dirt,

PCB warping is a common quality issue in surface mount technology (SMT) processing, severely affecting the performance and reliability of electronic products. This phenomenon is not caused by a single
