Design Your Own PCBSolderless breadboards are great for building and testing a circuit because they are reusable and don't require soldering. Designers will be able to easily create temporary prototypes and experiment with circuit design. Moving forward in the next phase of design, designers use prototyping boards where connections are soldered into place, creating a solid and more permanent connection.
However, if you want a real proof of concept or finish-quality look, you'll want to design your own printed circuit board (PCB). Designing your own PCB is easier and less expensive than you might think. Some major benefits to using PCBs are that they can be more easily mass produced and you get consistency. Not only that, but the component and circuit density can be increased greatly. And, personally, I like to be able add my own logo to my designs.
