Introduction
The pcb design course is now more than ever at the heart of the industrial activities of the most advanced countries, and the software is one element that makes the difference from the competitive point of view. More and more everyday objects have an electronic component inside, which makes them smarter and more performing.
If you also want to work or just simply understand the pcb industry, here is a free pcb design course online. Knowledge is practical and comprehensive, with zero-based quick start.
Preparation of pcb design course
PCB board design needs to provide information:
- Schematic diagram: a complete electronic document format that can generate the correct netlist
- Mechanical size: provide the identification of the specific position and direction of the positioning device, and the identification of the specific height limit position area;
- BOM list: mainly to confirm and check the specified package information of the equipment on the schematic diagram;
- Wiring guide: description of specific requirements for specific signals, as well as design requirements such as impedance and lamination.
What you should know about pcb design course——pcb design flow
Prepare necessary information
Including the preparation of component libraries and schematic diagrams. Before continuing the pcb design, you must first prepare the component library of the schematic SCH and the component library of the pcb. This is the place that must be emphasized in the pcb design courses online. When making the library of the schematic diagram, pay attention to whether the pins are connected to the output/output pcb board and check the library.
PCB structure design
Draw the pcb surface in the pcb design environment according to the determined board size and various mechanical positioning, and place the required connectors, buttons/switches, digital tubes, indicators, inputs, and output according to the positioning requirements. Special attention should be paid to the actual size of the components, the relative position and the size of the space between the components, and the surface on which the device is placed to ensure the electrical performance of the circuit board. This is the second point emphasized by pcb design classes. This is the second step of the pcb design course.
PCB layout
- The pcb layout is the most critical step of the pcb design course online. Make sure the schematic diagram is correct before layout (the advanced pcb design course reminds you that this is very important)
- The layout should pay attention to the placed surface equipment and the placement method of the equipment to ensure the feasibility and convenience of installation.
- The layout is white and the device is placed on the circuit board. At this point, if all the above preparations are completed, you can generate the netlist on the schematic, and then import the netlist on the PCB.
Wiring
The printed circuit board design courses remind you that wiring is the most important process in the entire pcb design. This will directly affect the performance of the pcb. In the pcb design process, wiring generally has three levels of division: the first is connection, which is the most basic requirement of pcb design. The second is the satisfaction of electrical performance. This is a measure of the eligibility of printed circuit boards. The third is beautiful. If your wiring is connected, then there is no place to affect the electrical performance. This is the fourth step of the PCB Design Course.
Add teardrops
In the circuit board design, in order to make the pad stronger and prevent breakage between the pad and the wire when making the mechanical board, a transition zone copper film is usually set between the pad and the wire, which is shaped like a teardrop, so it is usually called a teardrop. . The purpose of setting the teardrop is to avoid the contact point between the wire and the pad or the wire and the guide hole when the circuit board is subjected to a large external force.
Examination
The first check is to look at the Keepout layer, the top layer, the bottom layer topoverlay and the bottom overlay.
Electrical rules check: through holes (0 through holes-very incredible; 0.8 boundary line), whether there is a disconnected netlist, minimum spacing (10mil), short circuit (analyze each parameter one by one)
Power cord and ground wire check-interference. (The filter capacitor should be close to the chip)
Reload the network flag to check if the netlist has been modified-it works.
Check the wiring of the core equipment to ensure accuracy.
Recipients
The advanced pcb design course online was developed precisely with the aim of providing the necessary tools for the design of printed circuit board design courses and their requirements and is aimed not only at those who design, but at anyone involved with the design, development, and manufacturing of the PCBs at any level, from sales to management, to sourcing rather than quality. This is the last step of the PCB Design Course.
Conclusion
The above is a free pcb design course. With a simple pcb design course, it could be interested in making circuit board. The pcb design courses turn out to be very interesting when it follows you step by step from the beginning to the end, touching on interesting topics such as ground planes, the necessary steps for the automatic assembly of components and panelization up to in-depth lessons on decoupling capacitors, on electronic component packages and on vias.

Below You, Will Find The Answers To The Most Common Questions When Asked To Join PCB Design Course
Why do I have to learn how to design a printed circuit board? I get along so well with breadboards and breadboards.
Breadboards and breadboards are great tools for making circuit prototypes. To make something more stable over time and easily replicable, you need to design a printed circuit board.
Why should I invest in a course when I use free design tools? On Youtube, there are several video tutorials?
The advanced pcb design course online classes are well done but you do not have a clear map of which steps are necessary for the design and above all you do not know why you have to do them in a certain order.
Are special skills required to start the course?
No, the course is explained step-by-step and is suitable even if you do not have particular experience in electronics. It can help you to have already done some experiments with the main components (resistors, capacitors, diodes, transistors).
To learn how to design a printed circuit, is it enough to use free CAD? Should I invest in paid software?
Claim. To learn how to design printed circuit boards, free CADs are fine. You’ve probably heard of paid software used in professional environments, in companies. These softwares have advanced features such as the ability to build component databases or have tools and controls for routing high-frequency circuits. If you’ve never designed a printed circuit board before, you first need to become familiar with designing 2-layer and then 4-layer circuits. Free CADs are more than enough for this. Only later will you be able to start designing more complex circuits and using paid CAD.
During the pcb design course, I also learn how to make a printed circuit in my laboratory or in my home?
No. A clear map of how to design is provided in the printed circuit board design course. We do not recommend physically making a pcb first of all because you have to deal with corrosive and difficult to dispose of acids. Also, doing short research, you find several companies that charge affordable prices for making prototypes. Of course, it depends on the urgency with which you want to have the printed circuits available: in three/four weeks you can receive 10 2-layer pcbs with maximum dimensions of 100x100mm for just over €10 including transport costs. Finally, if you want to work in electronics, you must be familiar with the processes that are used. All companies (both the smallest and the most important ones) deliver the final production files to an external company that takes care of physically making the printed circuit.
How much is it worth pcb design course fee to you to know how to design a working circuit without having to cross your fingers when you connect the power supply and do the first tests?
In fact, the simple pcb path allows you to acquire all the knowledge to design 2 and 4 layer medium complexity printed circuits.
These two types of pcbs allow the creation of medium complexity circuits such as sensors, automation controls, battery chargers. It is a type of circuit that is commonly designed in the industrial field.
Obviously, watching a few videos is not enough to become an expert in 2 and 4 layer pcb design. With pcb design classes, you only gain knowledge. Then you have to get your hands dirty and do a lot, a lot of practice.
