Reverse Engineering PCB Wiring Card

Selection of PCB Raw Material when Reverse engineering Pcb wiring card

Reverse engineering Pcb wiring card base material include the organic and non-organic types, and the most important factors of reverse engineering Pcb wiring card raw material is dielectric constant, dissipation constant, thermal expansion parameter and moisture absorption parameters. Among them the dielectric constant will affect the track impedance and signal transmission rate when reverse engineering Pcb wiring card. for the high frequency circuit, the tolerance of dielectric constant is the one factor which should be taken into consideration, so for reverse engineering Pcb wiring card should choose the raw material with low dielectric constant.

2, Reverse engineering Pcb wiring card Procedure

Due to the application of Protel 99se software and its difference with Protel 98, as a result of that, it is necessary to discuss Reverse engineering Pcb wiring card by using Protel 99se.

1>     Since the Protel 99se use PROJECT database model management, so it is necessary to establish a database file to manage all of the Reverse engineering pcb wiring card schematic diagram and Layout;

2>     Schematic diagram from reverse engineering Pcb wiring card: in order to achieve the network connection, before proceed the schematic diagram design, all of the components used on the reverse engineering pcb wiring card must be able to be found from the electronic database, otherwise, designer should design the required components and store these parts into the database in advance. After that, designer just need to use the required components from it when reverse engineering Pcb wiring card, and make the electrical connection according to the schematic diagram;

3>     After the completion of reverse engineering pcb wiring card schematic diagram has been done, it will form a network list which can be used for the pcb wiring card reverse engineering usage.

4>     reverse engineering printed circuit board: a, confirm the pcb wiring card dimension and outline, reverse engineering pcb wiring card and definite its location, required space in the finished product, shape as well as the cooperation with other components.

a; Use the PLACE TRACK order to draw the pcb wiring card outline in the mechanical layer.

b; according to the surface mount technology requirement to make the tooling hole and reference point on the reverse engineering Pcb wiring card;

c; the component layout and placement;
