Nowadays, there are countless large and small PCB manufacturers in China, which, on one hand, reflects the stable development of China’s economy. On the other hand, it can be seen that the prospects of the PCB industry are good, especially with the breakthrough of artificial intelligence technology in the future. As well as the […]

The process of printing a circuit board, from a bare board to displaying a circuit pattern, is a relatively complex process of physical and chemical reactions. This article analyzes the final step-etching processing. Currently, the typical process for, printed circuit board (PCB) manufacturing, is “graphic plating”. That is, firstly, a layer of lead-tin resist is […]
PCB Materials are getting more and more expensive. April. 2021 Source: Elektronik PRAXIS The circuit board is mainly composed of copper, resin, and glass fiber. These ingredients are becoming scarcer and therefore more expensive. What is going on, what can you do now? The printed circuit board industry has only a few suppliers for each […]
Preface Rigid-flex board is a new type of printed circuit board that has both the durability of rigid PCB and the adaptability of flexible PCB. Among all types of PCBs, the combination of rigid and flexible is the strongest resistance to harsh application environments. Favored by manufacturers of medical and military equipment, Chinese companies are […]
PCB products, whether rigid PCB, flexible PCB, rigid-flex PCB, multi-layer PCB, and module substrates for IC package substrates, make a significant contribution to high-end electronic equipment. PCB industry plays an important role in electronic interconnection technology. This article makes the following analysis on the current development trend of PCB technology: 1. Development towards the road […]
Our customers could define the prepreg thickness and type in fabrication spec. If we do not have prepreg with the required thickness or types, we will make a very small change(by Engineering Query) to meet the layer stack-up and impedance requirements. Today our customer(Poland) told me that he is designing an 8 layer PCB that […]
When someone works on a multilayer PCB project, they have to calculate a stack-up for that PCB. Some of them may have some questions about how to choose material for layer stack-up of multilayer PCB. For example, using Isola 370HR for a 4L project assumed the finished board thickness is 1.6mm+/-10%, we can choose cores […]
PCB is the short name by Printed Circuit Board. PCB mechanically supports and electrically connects electronic components or electrical components using conductive tracks, pads, and other features etched from one or more sheet layers of copper laminated onto and/or between sheet layers of a non-conductive substrate. (From Wikipedia) There are several types of PCBs such […]
A lot of people like to judge the good and bad of the board based on the color of the PCB, in fact, the color of the PCB is not directly related to its performance. The function of the solder mask is to prevent the electrical components cause wrong welding during the welding process, and […]
Directional coupler, a passive device used in radio technology.The application of directional coupler as below: 1) For power synthesis systems. In the multi-carrier frequency synthesis system, a directional coupler with 3dB is usually used. (generally called 3dB bridge) 2) For receiver’s anti-interference measurement or stray measurement. In the FR test and measurement system, if the […]
