Electronics enthusiasts and designers everywhere often take delight in planning and fabricating their own printed circuit boards (PCBs). PCBs are professional-quality circuit boards that serve as the hearts and brains of electronics devices. The pathways between components such as resistors, transistors, and integrated circuits (ICs) are imprinted on the board with a conductive material.

Some people choose to make their own printed circuit boards. Such PCBs, while useful for prototyping and experimentation, can be difficult and time-consuming to produce on one's own. The board must be plotted out, etched, and submerged in a chemical bath in order to achieve the desired amount of conductivity.

What's more, the etchings of such homegrown PCBs are usually performed by hand, allowing for careless human error. Anyone who has worked with electronics before knows that the slightest mistake in a circuit--whether through a gap in the flow or through a solder bridge--can mean the end of a functional circuit. This is why those working in electronics virtually always prefer the precision of machine-made PCBs.

Finding Cheap and Free PCBs

There are several internet-based companies that will take your software-designed PCB plans and manufacture them into a real, functional circuit board. Keep an eye out for special deals from these companies, as they will frequently offer bulk discounts. It is even possible to receive some PCB designs for free when you order circuit boards from some manufacturers.
