Electronic PCB Card Cloning Signal Integrity
Electronic PCB Card Cloning Signal Integrity is a very important topic to be discussed in the process of PCB reverse engineering, we have discussion with tremendous engineers and they are always mumbling and keep on telling you how much dangers the signal integrity in the circuit board copying process and could be especially for the high speed one. They will tell you when the systematic clock surpass 500MHZ, the interconnecting signal on the Electronic PCB card could lead to the postpone on the time frequency route, and these signals postponed will naturally deteriorate the performance of printed circuit board.
And these engineers will also depict to you that these transmitting line can effectively and swiftly introduce the signal oscillation, over-pulse, and down-pulse issues which could severely affect the Electronic pcb card cloning signal integrity, these issues can greatly threaten the noise limitation as well as the monotonous uniformity principle. Much worse, the signal cross talk and electro-magnetic radiation can severely damage the device performance.
And then the digital circuit area and analog area must separated with each other as much as possible, and digital ground and analog ground must be isolated too to connect to the power supply ground finally. All of the ground lines embedded in each segments of the internal circuit must pay attention on the single point grounding rules, to reduce the signal loop area, and close the wave filter circuit.
In the space allowance scenario for signal integrity, all of the blocks better can be separated by the groundling lines, to avoid the signal decoupling interactively. Radio frequency Electronic pcb card Cloning’s key point is to research how to reduce the radiation capability and improve the anti-interference ability, rational layout and schematic design is the premise of stable quality assurance.
