The hole is too small to change the pads too big, all fixed network definition screw holes pad to ground or protect land.

Board has heavy devices or larger edge connectors and other devices should also force plus fixed screw holes, if there is a need to put in place a number of test pads, plus the best on the schematic. For large board, should be more in the middle of fixing screw holes. If the board space allows you can put some similar experiments on board wiring board area. Six Steps PCB copy board : according to the situation and then make appropriate adjustments and then the entire device is locked Prior arrangement with the mechanical dimensions related devices and locking devices, and accounted for a large position devices and circuits core components, and then a small external components. Note : the layout of parts, the mechanical structure should be from heat, electromagnetic interference, and other aspects to facilitate future wiring considered. Tip: automatic selection, use Shift + X or Y and Ctrl + X or Y to expand and tighten selected X, Y direction component. Upon completion of a simple layout, use automatic alignment neatly expand or tighten a package similar elements. Use automatic selection method can quickly gather a similar package of components, and then rotate, expand and organize into groups, you can move to the desired position on the board. New interactive layout options include automatic selection and automatic alignment. Use the mouse to select a component, press and hold the left mouse button, dragging the component to reach the destination, release the button, the element is fixed.

The key layout is the layout, most designers in the form of a manual layout. If automatic layout, run 'Tools' below 'Auto Place', use this command, you need to have enough patience. Protel99 enables automatic layout, you can also manually layout. PCB Design Step five: location arranged circuit board copy board part of the package, also known as the parts layout

Of course, you can artificially generated netlist directly in the PCB, and specify the parts package. Therefore, schematic design, the parts of the package may be forgotten, can be modified or supplemented in accordance with the design part of the package in the case of the introduction of the network table. In the schematic design process, ERC check the package does not involve the issue of the part. This step is a very important aspect, automatic routing PCB netlist is the soul, but also the impression of schematic design and design of the interface circuit boards, only after the network table is loaded to the circuit wiring version. PCB design of the four steps : Open all use to copy board PCB library files, transferred netlist file and modify parts package Note: Before drawing board to the frame, be sure to set the current layer Keep Out layer, which prohibits the wiring layer. Available for 3mm screws 6.5 ~ 8mm outside diameter and 3.2 ~ 3.5mm diameter pads can be transferred from another board or PCB izard in the standard plate. To be placed in a fixed place to put the pad hole of appropriate size. Ģ, the printed circuit board planned, primarily determines the frame board, including the size of circuit boards and the like. Most parameters can use the system default values, and these parameters after setting meet personal habits, do not go after the modification. PCB Design Step three: Set PCB design environment and draw printed circuit board version of the middle frame with hollow etc.ġ, the first step into the PCB copy board system is set up after the PCB design environment, including setting the grid size and type, the cursor type, version layer parameters, routing parameters and so on. Recommended that the devices themselves drawn into a library dedicated to establish their own PCB design files. PCB Design Step two: draw their own definition of non-standard package library device The inconsistency of some of the schematic and PCB footprint library Pin Pin name changed to the name of the device and PCB footprint library of consistent, especially, such as transistors. Ģ, manually change the network table is defined without pads on their feet and some other components fixed schematic connected to the network and it did not define any physical connection to ground or protect land. can not be schematic design, PCB design system directly into the PCB design system, you can directly access parts packaging, labor generate a netlist. Certainly, in some special cases, such as circuit boards is relatively simple, has had a netlist, etc. Step one PCB design: PCB copy board's early workġ, using schematic design tool to draw schematics, and generates a corresponding netlist.
