For you to make a custom printed circuit board, it is important to put your circuit together in a circuit maker software that has the capacity to make simulations. This is helpful in the sense that you can simulate your circuit and ensure that it is working. There are some great circuit simulation programs that even check for any possible circuit or component flaws.
After all the circuit simulations are well done, and it is clear that the custom PCB will function as expected, the next step is to put the components of the custom circuit together in a breadboard. This step is important in ensuring that your circuit works well in the real world. Another important trick is to use development boards to test the practical circuit. This is especially important where microcontroller programming is needed. With the development boards, you may not even need the breadboard to test every part of your circuit since the development board has the female and / or male headers and all that you need is the jumpers.
Having tested your circuit, it is time to make a more permanent custom PCB. This step helps to make sure that the working circuit is kept in the same working state for years. There are two major ways that this custom PCB can be achieved; making a custom PCB at home or sending the custom PCB designs to a PCB manufacturing company to do the job for you. A couple of years ago, a homemade custom PCB was the only option because sending out a custom PCB to the PCB manufacturers of that time was unreasonably expensive. Only big companies could afford a professional custom PCB manufacturing. Today, making custom PCBs has been made so easy that you do not have to get your hands dirty with do-it-yourself, homemade custom PCBs. Through a website like wellpcb.com, you just need to upload your custom PCB design Gerber files and make payment, then sit back for a week or two and you will have your boards ready.
