Before cloning multilayer PCB board, the designer needs to first determine the multilayer PCB board structure to be used according to the size of the circuitry pattern, the dimension of the circuit board, and the requirements of electromagnetic compatibility (EMC), that is, whether the process is to reverse engineering a 4 layers, a 6 layers,…
Many PCBs are no longer single-function circuits (digital or analog circuits), but rather a mixture of digital and analog circuits. Therefore, it is necessary to consider the mutual interference between them. through the obselete physical PCB sample, we can Optimize PCB Layout by Reverse Engineering PCB, obtain its original Gerber file and layout diagram. Especially…
The Gerber File format is an open 2D binary vector image file format. It is the standard file used by printed circuit board (PCB) industry software to describe the printed circuit board images: copper layers, solder mask, legend, etc. Designer can use this documents and send it to manufacturer for Printed circuit board production, normally…
Although good schematics do not guarantee good Layout, good layout begins with good schematics. As a result of that, when engineer try to Cloning Printed Circuit Board Schematic Diagram, be careful when drawing schematics and must consider the signal flow of the entire circuit. If there is a normally stable signal flow from left to…
PCB Board Layout plays a key role in high-speed circuits, but it is often one of the last steps in the Reverse Engineering High Speed PCB Board layout process. There are many problems with high-speed PCB board layout, through reverse engineering technique we can improve the performance; This paper mainly discusses the layouting problem of…
In below articles we would like to introduce some of the PCB Board drilling tips which can help designer not only decrease the production cost but increase the reliability of PCB Board: The inner diameter of the through hole is required to be 0.2mm (8mil) or more in principle, and the outer diameter is 0.4mm…
Via is one of the important components of a multi-layer PCB. The cost of drilling is usually 30% to 40% of the cost of PCB board manufacturing. From the perspective of PCB Board Via Designing , a via is mainly composed of two parts, one is a drill hole among the different layers, and the…
PCB Board Cloning Process is always related to record the information of components solder on the original PCB board, and then make a 100% perfect clone we can print the same silkscreen notification on the newly made PCB board. but sometimes the original PCB board doesn’t come with the silkscreen on it, in this case…
PCB prototyping means that after the PCB reverse engineering, engineer will conducts small quantity trial production order to the PCB manufacturer. As a matter of fact, There is no specific requirement for the quantity of PCB prototype production. Design engineer should place order to produce PCB prototypes before mass production to verify if PCB schematic…
Design PCB Analog/Digital Circuit starts from dividing its structure into four types of circuits (RF analog signals, interface circuits, common digital circuits, -48V, power supply and other high-power wiring areas) to reduce mutual interference between various types of circuits and improve resistance to interference outside the equipment and reduce external emissions. The long-distance reset line…
