Many friends always worry about printing PCB when they first learn about electronic circuit drawing. Especially friends who like to make their own circuit boards and craft drawings. In order to reduce unnecessary workload, it is necessary to learn more about how to set up PCB printing problems before printing PCB diagrams.
The following is an introduction to the printing PCB drawing setting problem of Protel99se, one of the mainstream PCB drawing software. To make it easier for everyone to understand, take the double panel as an example
When you want to consider printing a PCB circuit diagram, you must first know the basic elements of the circuit diagram-the layer relationship. A double-sided circuit PCB drawing includes at least the following layers of circuit diagrams, the top layer (Toplayer), the bottom layer (bootomlayer), the silk screen layer (topoverlay), the keepout layer, and the composite layer (multilayer).
The following briefly explains the meaning of each layer:
Top layer (Toplayer): The electrical layer of the actual circuit. A circuit board contains at least one electrical layer.
Bottom layer (bootomlayer): The electrical layer of the actual circuit. If it is a double-sided board, it is connected to the top layer through vias.
Silk screen layer (topoverlay): The component symbol mark layer in the circuit board, which is convenient for assembly and search for corresponding devices.
Keepoutlayer: The layer that protects the current electrical layer steps and effective range. It is generally used for PCB size positioning and is very useful when designing irregular-shaped PCBs.
Multilayer: A layer containing pads, vias, and tin on wires of the device.
A single panel should contain at least three layers: bottom layer (bootomlayer) + composite layer (multilayer) + keepout layer (keepoutlayer) to meet the actual plate making needs; double panels should at least be based on the single panel plus the top layer (Toplayer) to form the smallest Plate making requirements.
However, as amateur PCB printing, single-panel design is usually used for printing, while double-panel amateur production is relatively complicated. After opening and making the PCB board drawing, after confirming that the printer is installed, first click the print icon in the menu or switch to the print drawing preview page through File->Print/Preview in the menu.
It is not the desired single-layer drawing printing requirement, so use the printing settings to get useful layers. There are many ways. Here, first take the fastest way as an example to print out the top layer separately. Clicking Tools in the menu will list many printing layers for selection.
The printed drawings of various requirements in the circuit diagram are listed. Below, select the first item Create Final to establish the final electrical layer. This method of establishing the top layer diagram is only suitable for PCB boards with full-chip components. Select Yes in the dialog box that pops up after selecting the first item of the Create Final menu.
Before setting other operation options of the printer, the current page will be printed by default 1:1, and no other printed pages will appear. The above methods are suitable for the printing requirements of document PCB drawings. You can select various printing layers through the Tools menu item to achieve basic printing. The following print setting methods are suitable for amateur circuit board making and other requirements. Protel99se only prints the top layer by default. In order to print the bottom layer and the silk screen layer, you can use the Insert Printout in the Edit menu option to achieve multi-layer printing in any combination.
