1. The core advantages and key defects of immersion silver technology   Immersion Silver(ImAg)By chemically depositing a 0.1-0.4 μm dense silver layer on the copper surface, the PCB performance is significantly improved: welding strength is increased by more than 30%, contact resistance...

Ceramic PCB is a circuit board with ceramic material as the substrate, which plays a special role in electronic products. Compared with the common FR-4 material circuit board, ceramic PCB has more outstanding performance in thermal conductivity, insulation, high temperature resistance, etc., and is...

In the PCB (printed circuit board) manufacturing process,the surface treatment process directly affects its reliability, welding performance and service life. Different application scenarios have different requirements for surface treatment, so it is crucial to choose the right process. This article...

When you pick up a PCB, the first visual impact often comes from its bright colors: the classic green solder mask, the eye-catching white silk screen characters, or the dirt-resistant black coating on industrial equipment. These colors are not only a choice of design aesthetics, but also a functiona...

In PCB design, vias are key structures for interconnecting multi-layer circuits. Based on their penetration range and manufacturing process, vias are mainly divided into three types: through vias, blind vias, and buried vias. This article will systematically analyze their technical features and appl...

PCBs are usually composed of several layers with different functions, which work together to provide a guarantee for the stable operation of electronic products. Among them, the copper layer, soldermask layer and legend layer are the most critical parts, each of which plays a unique role and has a...

In the field of modern electronics, printed circuit boards (PCBs) connect the various electronic components in electronic devices and undertake the important tasks of signal transmission and circuit function realisation. Lithography is a critical and fundamental process in the PCB manufacturing proc...
