What is a Printed Circuit Board (PCB)?
A printed circuit board (PCB) mechanically supports and electrically connects electrical or electronic components using conductive tracks, pads and other features etched from one or more sheet layers of copper laminated onto and/or between sheet layers of a non-conductive substrate. Components are generally soldered onto the PCB to both electrically connect and mechanically fasten them to it. Printed circuit boards (PCBs) are the foundational building block of most modern electronic devices. Whether simple single layered boards used in your garage door opener, to the six layer board in your smart watch, to a 60 layer, very high density and high-speed circuit boards used in super computers and servers, printed circuit boards are the foundation on which all of the other electronic.
This skill is called PCB design and is highly useful. Before you start drawing wires and stuff, you need to know what circuit you want to build. So you need a circuit diagram. I recommend starting with something simple. Like a blinking LED. First, you need to install a PCB design software. You need to transfer your schematic diagram into a drawing of your printed circuit board. Because the software will compare what you are drawing to the schematics file.
And it will help you create the same connections. An important decision here is what footprint you should choose for the components. Through-hole or surface mount? Through-hole components are the easiest to solder. I recommend through-hole for beginners. Surface mount components are smaller, so they take up much less space. But smaller also means it could be harder to solder.
That said, it just takes a bit of practice to get used to surface mount components. So if your up for the challenge, then go for it. Take your time, and make sure it looks good ; Follow the design guidelines for drawing circuit boards. The classic way of sending a board layout to a manufacturer is by creating Gerber files from how to copy contacts from nokia lumia 520 to pc design.
But some ex. It usually takes a bit of time before your PCB is ready. So while you wait, make sure you have all the components you need. You have your circuit board, fresh out of the printer. You have ordered diy how to make a lampshade received the component. Prepare your workbench and get your soldering tools out. Lay out the components and the PCB on your how to print on pcb board. Have your computer with the PCB Design close by so that you can check the orientation and value of components if needed.

Printed circuit boards PCBs are the foundational building block of most modern electronic devices. Whether simple single layered boards used in your garage door opener, to the six layer board in your smart watch, to a 60 layer, very high density and high-speed circuit boards used in super computers and servers, printed circuit boards are the foundation on which all of the other electronic components are assembled onto.
A small subset of these types of circuits are called rigid flex circuits, where one part of the board is rigid — ideal for mounting and connecting components, and one or more parts are flexible, providing the advantages of flexible circuits listed above. A rapidly emerging PCB technology, separate from the ones above, is called printed electronics — typically very simple, very low cost, circuits that reduce electronic packaging expense to the level that electronic solutions can be developed to solve problems never considered before.
They are often used in electronics for wearable applications, or disposable electronic devices — opening many opportunities for creative electrical designers. They consist of electrical components and connectors linked via conductive circuits — usually copper, with the purpose of routing electrical signals and power within and between devices. The advancement and widespread adoption of technology in PCBs has paralleled the rapid advancement in semiconductor packaging technology and has enabled industry professionals to invest in smaller and more efficient electronics.
Founded in , Printed Circuits LLC has since become a ground-breaking printed circuit board manufacturer. Our broad selection of PCB designs, enables us to serve a wide range of industries around the world, including military, medical, aerospace, computer, telecommunications, and instrumentation.
Here we provide a comprehensive overview of printed circuit boards to provide relevant background information for what we do. Compared to traditional wired circuits, PCBs offer a number of advantages. Their small and lightweight design is appropriate for use in many modern devices, while their reliability and ease of maintenance suit them for integration in complex systems.
Additionally, their low cost of production makes them a highly cost-effective option. These qualities are some of the reasons PCBs find application across industries, including within the following markets:.
Medical electronics have significantly benefited from the introduction of PCBs. The thinner and smaller size of flexible and rigid flex PCBs allows for the manufacture of more compact and lightweight medical devices, such as hearing aids, pacemakers, implantable devices, and truly tiny cameras for minimally invasive procedures. Rigid-flex PCBs are a particularly ideal solution when looking to decrease the size of complex medical devices, as they eliminate the need for the flex cables and connectors that take up valuable space in more intricate systems.
Rigid, flexible and rigid flex PCBs are commonly employed in the aerospace industry for instrument panels, dashboards, flight controls, flight management and safety systems. The growing number of advances in aerospace technology have increased the need for smaller, more complex PCBs for use in aircraft, satellites, drones, and other aerospace electronics. Flexible and rigid flex circuits offer exceptional durability and mission survivability due to the elimination of connectors.
This makes them suitable for use in high-vibration applications, while their small and lightweight design reduces the overall equipment weight and, consequently, fuel consumption requirements. For applications where dependability is paramount, they serve as a highly reliable solution. As military technology advances to meet changing customer demand, more equipment integrates advanced computerized technology, requiring both the electrical and mechanical performance that is inherent in flex and rigid flex packaging.
These types of electronic packaging can withstand thousands of pounds of g-force without failure. The use of PCBs in industrial and commercial electronics has revolutionized everything from manufacturing to Supply Chain management — increasing information, automation and efficiency.
In general, they are a reliable means of directing equipment in increasingly automated facilities, enhancing production while decreasing labor costs. Nearly all PCBs are custom designed for their application. The designer uses this software to place all of the circuits and connection points, called vias, throughout the entire board. The software knows how each of the components need to interact with each other, and any specific requirements as well — such as how they need to be soldered to the PCB.
When the designer is done, the software exports two critical components, with which we will build their boards. The first is called gerber files, which are electronic artwork files that show every single circuit in the PCB, where exactly it goes, on every single layer of the board. The gerber files will also contain drill files, showing us where exactly to drill the holes to make all the via connections we discussed earlier. They will also contain soldermask and nomenclature files — which are discussed later, as well as a file that shows us exactly how to cut out the perimeter of their board.
All PCB designers — whether rigid, flexible, or rigid flex — use these files to communicate to PCB manufacturers exactly how they want their boards built. They include one other item that is critical for the PCB fabricator — a fabrication print. The fabrication print carefully details all the requirements of the boards, that are not in the gerber files. The fabrication print for example will detail what materials we are to use building their board, what size drilled holes they would like, any special manufacturing instructions or specifications we need to meet, and miscellaneous information like what color soldermask or nomenclature they would like.
As PCBs are highly customizable, they can be designed and manufactured to various flexibilities, sizes, and configurations to fit almost any application. The primary materials used in the manufacture of PCBs are fiberglass or plastic substrates, copper, solder mask, and nomenclature ink.
Rigid PCBs often use FR4 or polyimide fiberglass, while flexible circuits and rigid-flex flexible layers typically use high-temperature polyimide films. The purpose of the substrate is to provide a non-conductive base upon which the conductive circuits can be constructed and insulated from one another. Polyimide and LCP laminates are typically used in high reliability or high signal speed applications.
Polyester and polyethylene napthalate laminates are primarily chosen for their low cost, and usually are just single layers of circuitry. Due to its high electrical conductivity, copper is the most used conducting material for circuitry in PCBs. The laminates described above, all come with thin sheets of copper foil laminated to one or both sides of the plastic. The thickness and number of layers required are largely dependent upon the application for which the PCB will be used. Soldermask is a liquid, usually an epoxy material, that is applied onto the outerlayers of rigid PCBs.
Soldermask is primarily designed to insulate the copper circuits on outerlayers from oxidation from the environment. Soldermask is also designed to control and retain the flow of solder when the components are assembled to the PCB. Without soldermask, the liquid solder could flow out onto the surface of the PCB, connecting two adjacent circuits and short out the board. The most common color for soldermask is green, but blue, black, red, amber, clear, white and many other colors exist as well.
Once the soldermask layers are completed, identifying information, marks and sometimes bar codes, are printed onto the soldermask.
These marks are called nomenclature, and they will also be defined by files that were included with the other gerber layers. They are printed onto the solder mask to help assure accurate assembly of the PCB. PCBs come in a variety of designs, so it is important to have a thorough understanding of the design process.
Some of the key elements to consider when designing a PCB include:. Selecting the right PCB design to suit these considerations significantly impacts manufacturability, production speed, product yield, operation costs, and lead times. At Printed Circuits, we make it our goal to meet and exceed industry standards and have obtained a wide range of certifications and accreditations to do so, including:.
We have also obtained UL 94 V-0 qualification for rigid-flex and flexible circuits, with the largest listing of UL ratings for rigid flex worldwide. So, your boards can be 94 V-0 certified without additional testing thus expediting the fabrication and delivery of our PCBs. Once complete, the PCB board is ready for components to be assembled to it. Most commonly the components are attached to the PCB by soldering the components directly onto exposed traces — called pads — and holes in the PCB.
Soldering can be done by hand, but more typically is accomplished in very high-speed automated assembly machines. The use of either depends on the size of the components and the configuration of the PCB. SMD is useful for directly mounting small components on the exterior of the PCB, while THT is ideal for mounting large components through large pre-drilled holes in the board.
Although all PCBs have the same fundamental objective, they are available in a wide range of designs and configurations to meet the needs of various applications. Some of the different types available on the market include:. Rigid PCBs are constructed of a rigid fiberglass substrates, making them practical and inexpensive, but inflexible. They are easier and less expensive to manufacture than their more flexible counterparts but much less versatile and hard to fit into unusual geometries or small areas.
Flexible PCBs feature relatively good bending and folding capabilities to fit into confined and oddly shaped spaces. This quality makes them highly versatile and able to be used to package smaller electronic devices. Compared to rigid PCBs, they can offer greater resistance to heat.
They are an excellent choice when ultra-light packaging is a key requirement. Additionally, they are more durable and reliable while retaining great strength and flexibility. Printed circuits boards enable professionals across a diverse set of industries to optimize the performance and production of their electronic systems.
Through careful selection of materials and PCB fabricator, it is possible to create packaging for your electronic device, optimized for its end application. At Printed Circuits LLC, we are a leading manufacturer of flex and rigid flex printed circuit boards.
