Nowadays, with a wide range of electronic products, electronic equipment is involved in almost every industry, and a good electronic design concept can make our life easier and enjoyable. PCBA design is based on the circuit diagram to achieve the function what the designers need, mainly refers to the layout of circuit design, and the need of considering the layout of the external connections. So how do you learn PCBA design as a beginner?

PCBA design tutorial for beginners

  • Step 1 of PCB design

Using Schematic design tools to draw schematics and generating the corresponding network table.

  • Step 2 of PCB design

Drawing their own definition of non-standard devices package library, it is suggested to put all of the components you have painted into a proprietary design file of your own PCB library.

  • Step 3 of PCB design

Setting the PCB design environment and drawing the printed circuit board version, containing the middle of the hollow and so on. It is important to note that you must set the current layer to the Keep Out layer before you draw the border of the circuit board, that is, the wiring layer is prohibited.

  • Step 4 of PCB design

After opening all the PCB library files you need to use, switch to the network table file and modify the part package.

  • Step 5 of PCB design

Layout the location of the circuit board and the part of the package, also known as the layout of the parts. Protel99 can be automated or manual layout. The parts layout should be considered comprehensively from the aspects of mechanical structure, heat dissipation, electromagnetic interference, and convenience of future cabling.

Note: when choosing automatic, the use of shift + X or Y and Ctrl + X or Y can expand and shrink of the selected component X, Y direction.

  • Step 6 of PCB design

Adjusting accordingly , then locking all the devices.

  • Step 7 of PCB design

Setting rules of PCB changed board routing, Considering the security distance, the line level and direction, cross hole shape and line width, and so on.

  • Step 8 of PCB design

Automatic wiring and manual adjustment of printed circuit boards.

1, Click the menu command “Auto Route/Setup” to set up the automatic routing function.

2, Click the menu command “Auto Route/All” to start automatic routing.

  • Step 9 of PCB design

Switching to the single layer display mode (click the menu command Tools/Preferences, select the single layer Mode in the dialog box display), pulling the line of each wiring layer tidy and beautiful, and finally canceling the single layer display mode, saving the disk.

  • Step 10 of PCB design

Putting into copper clad area

  • Step 11 of PCB design

Lastly, to do DRC again.

Selecting the Clearance Constraints Max/Min, Width Constraints, Short Circuit Constraints and Un-Routed Nets Constraints items, and pressing Run DRC button, correcting if there is any mistake. Saving all if they are correct.

  • Step 12 of PCB design

Sending Email or copying to the manufacturer, indicating the material and thickness of the board.

Generating the BOM file and exporting it into a format that conforms to the company’s internal requirements.

How to draw a circuit diagram?

  • PCBA Design Layout

Drawing a circuit diagram is not that difficult if you know the basics. Here are some tips and guidelines:

Learn and understand all the common symbols and abbreviations for electronic components to be used on the diagram.

Using a ruler, draw connecting wires as straight lines. Use following symbols: ‘blob’ () at each junction between wires, label components (resistors, capacitors, diodes etc.) with their values, the positive (+) supply should be at the top and the negative (-) supply at the bottom. Negative supply is usually labeled 0V, zero volts.

For complex circuit diagrams, start from left to right. So that signals flow from left to right (inputs and controls should be on the left, outputs on the right).
