The main parasitic components generated by circuit board wiring are resistance, capacitance and inductance. In the process of the PCB Board Circuit Diagram Reverse Engineering , all parasitic components have the opportunity to interfere with the circuit performance. When a system mixes digital and analog components, careful reverse engineering PCB card is the key to…
Printed Circuit Board Copper Plating is another important method for PCB board surface treatment: In this process, all surface areas and drill holes are plated with copper, and some resist is poured on the unneeded copper surface, and then an etching resist metal is plated. Even for a medium-sized printed circuit board, this requires an…
Growing a metal build-up layer on the circuit board tracks and through holes can electroplate the circuit, which is described as PCB Board Circuitry Pattern Electroplating: In this process, only the places where the circuit patterns and through holes are designed accept the generation of the copper layer and the metal plating of the etching…
The precise technology required by electronic products and the strict requirements of environmental and safety adaptability have promoted considerable progress in PCB Circuit Board Electroplating Practice and specify the printed circuit board electroplating necessity. This is clearly reflected in the technology of manufacturing high-complexity and high-resolution multilayer circuit boards. In electroplating, through the development of…
The interconnection of various modules in electronic equipment often requires the use of a printed circuit board socket with spring contacts and a printed circuit board with connecting contacts designed to match it. These contacts should have a high degree of wear resistance and very low contact resistance to illustrate the Necessity of Printed Circuit…
On the printed circuit board, copper is used to interconnect the components on the substrate. Although it is a good conductor material for forming the pattern of the conductive path of the printed circuit board, it will also be exposed to the air for a long time. It is easy to lose luster due to…
Reverse Engineering Amplifier Mixed Signal PCB Board Layout Design can use partition design method to reduce the mutual interference between digital and analog signals; Before redesigning PCB board layout for better emc performance, we must understand the two basic principles of electromagnetic compatibility (EMC): The first principle is to minimize the area of the current…
Relayout Printed Circuit Board Gerber File must follow some rules strictly in order to ensure the out of standing performance of PCB Board than original one, because the purpose of re-route multilayer pcb board layout design is to improve the original PCB functionality; Because the impact interference generated by the transient current on the line…
When we are processing Reverse Engineering High Speed Circuit Board Drilling Drawing, the seemingly simple through holes (vias) often bring a large error effect to the redesign of printed circuit board layout. The adverse effects caused by the effect can be tried in the design: 1. From the consideration of cost and signal quality, choose…
Reverse Engineering PCB Board Gerber Through Hole File will normally comes with some Side Effect, the most obvious one is the Parasitic inductance of vias; Similarly, the parasitic inductance and the parasitic inductance of the via hole. In the reverse engineering of high-speed digital circuit board, the harm caused by the parasitic inductance of the…
