Single Side Board Proofing Design Process
Jul 05, 2017

Single Side Board features:

The so-called Single Side Board, that is, on the most basic PCB, all the parts in one side, and the wires are all concentrated on the other side. Because the wires only appear on one side, we call this kind of PCB called Single Side Board. Because the Single Side Board in the design of the line there are many strict restrictions (because only one side, the wiring can not cross and must be around the path), so now has not used, are generally used in the early circuit boards;

Single Side Board wiring diagram to the main network printing, that is, printed on the copper surface of the resistance agent, after etching and then anti-solder mark on the mark, and finally to punching processing parts to complete the hole and shape. In addition, a small number of diverse production of products, the use of photoresist to form a pattern of photography.

According to the figure we can see some things, but the figure is not entirely accurate, so the picture can only be used as a reference, the following we have to look at the design process is what it looks like.

1, prepared part:

At the beginning of the PCB layout, we should first complete the schematic design, get a correct schematic, which is the basis of Single Side Board proofing design. Through the schematic we can get a link to the properties of each device network table, in addition, according to the device parameters, we can find the relevant component data and the establishment of all components of the package. In addition, the need for structural parts with the board and frame size and the location of the installation, the location of functional excuses.

2, the specific operation part:

First of all need to import all the packages and network tables into the framework of the establishment of the PCB file. During the import process, some component packaging errors may be suggested. Please follow the error message to rectify the error.

3, fixed structure related devices:

You want to be fixed, such as LED, buttons, deck, LCD, infrared transmitter and other devices. Move these devices to the corresponding installation location, and select the lock in the property to prevent misuse.

4, the general layout:

The purpose of the general layout is to determine the location of the various functional modules, in the PCB design, the general default is:

In addition to the devices that need to be mounted on the surface, all patch devices are placed on one side of the plug-in device, typically the bottom;
