“Noise problem!” – This is the problem that every PCB Board engineer will hear. In order to solve the noise problem, it often takes several hours to carry out laboratory tests in order to find out the culprit, but in the end, it is found that the noise is caused by improper PCB layout of…
Reverse Engineering Circuit Board to Reduce Noise & Electromagnetic Inteference can be carried out through below practical aspects: The printed circuit board is divided by frequency and current switching characteristics, and the noise component is farther away from the non-noise component. Single-panel and dual-panel single-point power supply and single-point grounding, power supply track, and grounding…
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…
