How to select PCB copy software

The quality of the board reading software mainly depends on whether the functions are complete. It is better to do all the work in the board reading software so that the effICiency is high. It is best to support PROTEL99SE in the placement of components. The 99SE component library is very rich and can be downloaded from the Internet. This is also a very important thing. The era of making components by hand for PCB writing is over, because there are hundreds of elements in many BGP component packages, and it is too expensive to build components by hand. In order to ensure the stability and reliability of the circuit, a large piece of copper sheet should be connected to the power supply or ground when designing the circuit, which can reduce the noise and interference of the circuit.

Therefore, the problem of copper laying on the network is involved. For complex circuit boards, there are many connections and many isolations on the copper laying. If this problem is not solved properly, copper laying cannot be realized. So we must define a network to lay copper ("the same network is connected, but different networks are isolated"). SIMply filling all the copper sheets will cause short circuit. This is also a key issue in measuring board copying software. After selecting the software with perfect functions, in order to ensure the perfect effect, the copy board of double-layer board and Multilayer board should also have rich experience and skilLED skills in technology. As the holes of the same double-layer or multi-layer PCB are in the same position, but the circuit connections are different, when the wiring rules of the original board are described in the board copying software, the PCB files of the top layer that have been copied from the double-layer board are stacked on the scanning image of the other layer, and the vias of the two layers are overlapped, and then the top layer circuit and the silk screen are set not to be displayed. The circuit of the other layer is described according to the vias position, so that, The exported PCB file contains the data on both sides of the double-sided board. Similarly, multilayer boards only need to be sanded off the surface layer with sandpaper after the surface layer PCB file drawing is drawn, so that the inner layer routing rules are exposed, and then copied out with the same skills with the help of board copying software. At present, PROTEL99SE is the most commonly used board reading software in the MARKet, and quickpcb 2005 V3.0 and various versions of color board reading software are also used.

Among them, Protel99SE was originally an EDA design software applied to the Windows9X/2000/NT operating system. Using the design library management mode, it can carry out networking design. It has strong data exchange capability, openness and 3D simulation function. It is a 32-bit design software, which can complete circuit schematIC design, Printed Circuit Board Design and programmable logic device design. It can design 32 signal layers, 16 power supplies - strata and 16 machined layers. All operations of quickpcb 2005 V3.0 software conform to the operating habits of most designers, which can greatly improve the efficiency of PCB board copying and relieve the operators from the pain of detection. The one-time qualification rate of the board can also be further guaranteed.
