What is bare PCB?
Bare PCB, or bare board, refers to an untreated, unpopulated printed circuit board (PCB). Bare boards are generally used in the prototype and production of electronic products. They provide a platform for soldering components into place on the PCB. The bare boards are made from insulating materials and have copper tracks etched on them, which act as electrical connections between different parts of the board. A bare PCB board can also be used to test electronics concepts or debug circuits.
An experienced engineer or technician can use a bare board to test new circuit designs or troubleshoot existing ones. That is because bare boards are cheaper and faster to produce than fully populated PCBs, allowing for quick experimentation and development of products. Furthermore, bare boards are also more efficient than pre-manufactured components, as the user has complete control over bare board design and bare PCB layout. That allows for shorter production runs, which can lead to cost savings on production. Bare PCBs also provide a more reliable platform than that pre-manufactured components and are less prone to failure.
In Viasion, we produce reliable bare boards for various industries such as industry, consumer electronics, telecommunications, power & energy, medical, aerospace, automotive, military and medical.

The manufacturing process of bare PCB
Manufacturing a bare printed circuit board (PCB) requires many steps, from designing the circuit layout to PCB assembly and testing.
The process usually involves chemical etching, drilling, plating, and soldering. The bare printed circuit board starts with the design of the circuit layout. That is generally done using computer-aided design (CAD) software, where the components and connections are laid out on a bare board.
Once the circuit design is complete, it is sent to a bare PCB board manufacturer who will produce the bare board. The bare printed circuit board is manufactured by etching away unwanted copper from a laminate board. This process requires several steps, including applying a resist layer that prevents the etching of the copper, exposing and developing a pattern on the board using light or other imaging techniques, etching away unwanted copper, and then removing the resist layer.
After this process is complete, drilling is done to create holes for components like integrated circuits (ICs). Finally, the bare PCB is plated with a thin metal layer to protect it and make it more durable.

Frequently Asked Questions
As mentioned above, a bare PCB, or a bare board, is an unpopulated printed circuit board (PCB).
A bare PCB (Printed Circuit Board) is a circuit board with only the bare essentials, such as the copper tracks, connection points and components. It is usually used to create an electronic device prototype or test out circuit designs. In addition, it can be used as an input device in Raspberry Pi by making electrical connections between the bare PCB and other external devices. The bare PCB can then be controlled manually or by using software like Python code to give instructions for controlling specific functions within Raspberry Pi. That will enable users to create custom input devices that work with Raspberry Pi’s GPIO pins for different applications.
A bare PCB product such as a Raspberry Pi must pass Electrostatic Discharge (ESD) testing to achieve a CE mark. ESD testing evaluates the voltage and current that can be safely discharged onto the bare PCB without compromising the device’s performance or causing any damage. The bare PCB must withstand electrical discharges up to a certain level before the ESD testing succeeds. Bare PCBs must be thoroughly tested for ESD, as these products can be vulnerable to electrostatic events and surges in electrical current, which could damage the device or lead to safety concerns.
Since we only produce custom bare boards, every bare PCB boards are different in material, stackup, layers, surface finishes, so it is really impossible quote a bare PCB price without PCB files. Please send Gerber files to our sales team for a free bare board quote immediately.

When selecting a bare PCB, it is essential to consider factors such as size, number of layers, copper thickness and pour, material type and substrate thickness. In addition, one should also consider other features such as trace widths, hole sizes, solder mask type and colour, silk screen quality, plating types and finishes, etc. While bare PCBs are often designed to be used in various applications, it is crucial to ensure that the chosen bare PCB meets the project’s specific requirements. By understanding these components and their specifications, one can make an informed decision when selecting the best bare PCB for their project.
Simply put, the bare PCB design process begins with determining what type of board is needed (single-sided, double-sided or multi-layered) and what components will be used. Once these items are determined, a bare PCB layout is created. This design includes a copper layer that acts as a circuit board trace path for current to flow when power is applied and holes around the board’s edges for mounting components. Any bare PCB designers should know all these basic requirements.
The fabrication process for bare PCBs typically involves the main steps below:
A substrate material like FR-4 is cut to size and prepped with a chemical etch resist.
The etch resist is applied to the substrate to create the desired circuit trace pattern.
The substrate is etched using a chemical reaction to remove any copper not protected by the etch resist.
After etching, the bare PCB is cleaned with an alkaline solution and then covered with a protective coating to prevent oxidation.
The shelf life of bare Printed Circuit Boards (PCBs) varies depending on the material and construction design used in the boards. Generally, bare PCBs have a shelf life of up to 3 years if stored in a cool, dry place away from direct sunlight and with little dust or other particulates exposure. The exact lifespan will depend on the materials used and the manufacturing process, but bare PCBs are generally expected to last many years.
Yes, we supply all kinds of bare led printed circuit board, such as FR4 boards, aluminum bare boards, metal core bare boards, ceramic bare boards etc.
In Viasion, we make sure all our bare boards are are tested. The bare board testing we are doing now including: dedicated fixture bare board testing, flying probe bare board testing and universal bare board testing.
A bare PCB is a circuit board without any electronic components, while a populated PCB is a circuit board with all PCB parts assembled. Here at Viasion, we produce bare PCBs and assemble bare boards with electronic components.
