Since the sensitivity of electronic equipment is getting higher and higher, which requires the anti-interference ability of the equipment to become stronger and stronger, Therefore, Reverse Engineering PCB to Reduce Noice and Electromagnetic Inteference has become more difficult. How to improve the anti-interference ability of PCB has become one of the key issues that many…
PCB board manufacturers use a wide variety of solder resist inks, which are essential for manufacturing of PCB boards. Judge quality of PCB Solder resist ink is basically determined by several factors such as viscosity, plasticity and fluidity. In addition, it is necessary to consider whether the formula is scientific and environmentally friendly. ViscosityThe abbreviation…
PCB Reverse Engineering Impedance Matching is a suitable way to match a signal source or transmission line to a load. According to the access method, the impedance matching has two modes: serial and parallel. According to the frequency impedance matching of the signal source, it can be divided into low frequency and high frequency. 1st…
As for open source hardware Circuit board, one of the most important point is the open schematic diagram, through schematic diagram, we can know the input and output of a module, as well as the integrated circuit type applied on it as well as other information related to it. so we have to learn Circuit…
Text Symbol of PCB Schematic Diagram are an important part of the circuit diagram especially when redesign PCB board. In order to further emphasize the nature of the graphical symbols, and also to analyze, understand and explain the convenience of the circuit diagram, the text symbols of the components are marked next to the graphic…
How to Read PCB Schematic Diagram Swiftly, first of all we need to figure out what is a schematic? The schematic diagram, also known as the circuitry diagram, is a drawing that reflects the electrical connections of the various components in the assembled printed circuit board. The circuit diagram consists of some abstract symbols and…
High Quality PCB Board Features include below aspects: After the components are assembled properly onto the PCB board, the electronic device should be easy to use, that is, the electrical connection should meet the requirements; The track width, track thickness and track spacing on the PCB board meet the requirements, so as to avoid heating,…
With the rapid development of the mobile phone, electronics and communications industries, and the continuous growth and rapid growth of the Printed circuit board industry, the requirements for the number of layers, weight, precision, materials, color, and reliability of components are increasing, as a result of that, the importance of Identify Printed Circuit Board Quality…
Today let’s talk about the difference between PCB Reverse Engineering and PCB Design, PCB Board design is just as the name suggests: design the circuit board as required. Circuit board reverse engineering is simply to customize the board according to the provided physical printed circuit board sample. The circuit board design is mainly because the…
When engineers just entered the PCB maintanence industry, the most contacted are all kinds of PCB circuit boards. Attentive engineers can find that most of them Choose Green as PCB Solder Resist Color. Why? Painting is a technical requirement. First, both sides of the PCB are copper layers. In the production of PCB boards, the…
