PCB Circuit Card Copying Setting

In the process of PCB Circuit Card Copying, USB, DDR/DDR2, PCI-X, PCI-E and RocketIO et. gadget tools is dome to become the effective tools for engineer to march into the new design market without any questions, and these gadgets have already presented the general situation, specific description or other difficulties engineers will probably encounter, and simulation process as well as how to create the restriction for Pcb reverse engineering pre-preparation process. It can provide the descriptive documents together with the program which has provided the designer a advanced chance to master the new technology.

Normally, it can switch the data through a single route cross talk channel, and this single direction cross-talk channel can lay-up to 1-, 2-, 4-, 8-, 16- and 32- width installation. Each channel can carry a bit of data, as a result of that, databus can handle the data width from 8 bits to 256 bits, and through using certain type of error detection skill to retain the data integrity through PCB reverse engineering technique.

However, due the high speed data transmission rate, it will directly lead to other copying issue. The clock recovery under the high frequency has become heavy burden of the whole system, since the clock will be required to lock the input datastream in a relative fast speed, and decrease the trembling from all of the cycles for the sake of more circuit stability through Pcb board reverse engineering inspection, and the power supply noise can also bring other problems on the whole process, this type of noise add up the possibility of severe trembling and make the opening of layout become more and more difficult. Besides, how to reduce the shared model noise has become another challenge, and solve the IC footprint, cable and connector loss effect.
