How to choose PCBA copy board software
    The quality of the copying software mainly depends on the completeness of the functions. It is best to do all the work in the copying software, so that the efficiency is high, including the placement of components that support PROTEL99SE is the best, and the 99SE component library is very good. Rich, can be downloaded on the Internet. This is also a very critical matter. The era of manual PCBA copying of components has passed, because there are hundreds of elements in many BGP component packages, and it is too expensive to build components manually.
 
     For the stability and reliability of the circuit, it is generally necessary to connect a large piece of copper to the power supply or ground when designing the circuit, so as to reduce the noise and interference of the circuit. Therefore, it involves the problem of copper paving on the network. For complex circuit boards, many of the copper layers are connected and many are isolated. If this problem is not solved well, copper paving cannot be achieved, so here must be Define the network to lay copper ("the same network is connected, but different networks are isolated"). Simply filling everything with copper will cause a short circuit. This is also a key issue for measuring copy board software.

      After choosing the software with perfect functions, in order to ensure the perfect effect, for the copying of double-layer boards and multi-layer boards, you should also have rich experience and skilled skills technically. Since the same double-layer or multilayer PCBA board has holes in the same position, but the circuit connection is different, then when drawing the wiring rules of the original board in the copying software, stack the top-level PCB file that has been copied from the double-layer board. On the scanned image of the other layer, the vias of the two overlapped, and then set the top line and silk screen to not display, and trace the line of the other layer according to the position of the via. In this way, the exported PCBA file contains the two sides of the double panel. material.
 
   The same applies to multi-layer boards, except that the surface layer needs to be polished with sandpaper after drawing the surface PCB file to expose the inner wiring rules, and then copy it out with the same technique with the help of copying software.
 
At present, the most commonly used copy board software on the market is PROTEL99SE, and the other is quickpcb 2005 V3.0 and various versions of color copy board software.
 
    Among them, Protel99SE was originally used in the EDA design software under the Windows9X/2000/NT operating system. It adopts the design library management mode and can be designed for networking. It has strong data exchange capabilities and openness and 3D simulation functions. It is a 32-bit The design software can complete circuit schematic design, printed circuit board design and programmable logic device design, etc., and can design 32 signal layers, 16 power-ground layers and 16 machined layers.
 
     All the operations of quickpcb 2005 V3.0 software conform to the operating habits of most designers, which can greatly improve the efficiency of board copying and relieve the operator from the pain of detection. The one-time pass rate of the copy board can also be further guaranteed.
 
Features:
Place pads, holes, lines, arcs, vias, components, FILL, POLYGON, text;
Attribute setting and grid setting of each element;
The CTRL key automatically captures the grid and the center of the element;
SHIFT key to select, select, cut, copy, delete, rotate, mirror and repeat functions; the quality of the copy software mainly depends on whether the function is complete, it is best to do all the work in the copy software , Such efficiency is high, including component placement support PROTEL99SE is the best, 99SE component library is very rich, which can be downloaded on the Internet. This is also a very critical thing. The era of manual PCB copying of components has passed, because there are hundreds of elements in many BGP component packages, and it is too costly to build components manually.
