What is PCB fabrication & assembly?

Our PCB fabrication and assembly service is a one-stop solution for engineers needing to manufacture electronic devices, which includes PCB fabrication, component sourcing, and final assembly. Traditionally, these services are often separated, making it difficult for engineers to organise as blank PCBs have to be shipped to an assembly service while simultaneously needing to source components suitable for use in automation equipment (such as pick and place). By combining all these processes into a single service, engineers can spend more time on product development while our software-driven solutions intelligently orchestrate the entire supply chain to produce fully populated, high-quality circuits.

Our PCB fabrication & assembly services start with the manufacture of PCBs. Customer designs are checked for potential design errors that may conflict with our manufacturing processes. Once designs have been confirmed, manufacturing files are produced that include CNC drill files and transparent plots for layer imaging. Using a series of different manufacturing steps, layers are drilled, plated, imaged, and then laminated to create traces and vias. The final step in PCB fabrication involves the application of solder masks, component legends, and surface finishes such as HASL and gold.

Once the PCB has been fabricated, it is sent to our assembly facilities which use pick-and-place machines to place components automatically. Depending on the component being placed, these fully automated machines can use multiple placement heads to position up to 15 components per second. After all the parts have been placed, the PCB is then sent through a reflow oven which solders all components simultaneously. During this stage, it is essential that the heat of the reflow oven is separated into zones with varying temperatures so as not to damage components, the PCB, and ensure high-quality solder joints.

Finally, PCBs undergo automatic optical inspection (AOI) to guarantee the quality of solder joints, the position of components, and to identify any potential damage during manufacture. The high speed of AOI enables boards to be rapidly imaged and checked without needing to rely on human labour, thus reducing costs and increasing production rates.

How does digital manufacturing work?

It’s no secret that PCB fabrication, component sourcing, and assembly can be tricky to get right, especially if an assembly service has specific PCB requirements, or won’t accept certain types of component reels. Worse, trying to source components from numerous distributors and coordinate different orders can be a nightmare for both engineers and PCB assembly services alike.

To help engineers with this, Ponoko has developed an entirely digital manufacturing service that separates design engineers from manufacturing processes, including part ordering and sourcing. In addition to this, our digital manufacturing also connects our assembly sites with distributors over a single network that provides real-time communication and order placement. The moment a PCB is ready for manufacture, the component list is checked against our partnered distributors, and the best price is obtained while simultaneously organising the entire order process.

In addition to logistics management, our digital manufacturing services also provide tools for engineers to get rapid quotations. This removes the need for engineers to get numerous quotes for complex supply chains that can often take weeks.

How much does PCBA assembly cost?

Due to the countless options and variations associated with PCBs, there is no one single answer for their cost. However, the four main factors that affect the price of PCB assembly services include the size of the PCB, the number of layers used, the total number of components being assembled, and whether there are any components that cannot use automation processes.

For example, basic 2-layer PCBs that use a handful of commonly used SMD components will be very cheap, but larger PCBs with more than four layers and hundreds of SMD components will be more expensive. In addition, engineers should also try to avoid components that are not compatible with automation processes (such as some connectors and wires), as these require manual soldering, which is a time-consuming process (and thus faces significant labour costs).

Hardware quality, at software speed

The two largest factors that affect manufacturing processes are quality and speed, and increasing one usually results in the loss of the other. However, thanks to our digital manufacturing capabilities, we are able to offer industry-leading quality assembled PCBs, approaching software speeds. As our digital manufacturing process utilises software to orchestrate PCB fabrication with component sourcing and assembly, quotation times and logistics are massively reduced, while logistical optimisation ensures continuous production.

But to really demonstrate confidence in our software-driven manufacturing services, all assembled PCBs come with a 365-day guarantee which provides engineers with a level of protection rarely seen from other manufacturers. In addition to this guarantee, we have manufactured over 2 million products for over 35,000 customers, and with a precision part rate of 99.3%, there is a reason why ambitious engineers choose Ponoko.

What is PCBA used for?

The importance of electronics in daily life sees PCB fabrication and assembly used in every industry across the planet. Whether it is desktop PCs, kitchen appliances, medical devices, or IoT sensors, wherever electronics are found, PCBA is almost guaranteed to be used. The automated nature of PCBA makes it extremely economical, and the development of automatic optical inspection and probe testing enables most quality controls to be done by computer, further making PCBA highly efficient.

And unlike many other manufacturing processes, PCBA is used for both prototyping and mass production because the manufacturing process is identical. Of course, prototypes can be hand soldered, but the move towards extremely small SMT parts such as BGA and MLF makes hand soldering impractical and time-consuming. Thus, engineers opt for PCBA, even if only a handful of boards are needed.

With regards to some of the most popular industries, the IoT and computer industries are the most involved with PCBA as they are, by nature, entirely electronic. The medical industry has also come to rely on electronics thanks to the developments in sensor technologies, and the automotive industry has become mostly dependent on electronics for engine control, safety monitoring devices, and the introduction of EVs.

Smart IoT sensors

The automated nature of PCB fabrication and assembly services makes it perfect for the mass production of low-cost miniature devices. One such example are smart IoT devices used in smart city applications, whereby thousands of sensors are used to gather environmental data, provide control over infrastructure, and learn from their surroundings. These types of devices often consist of a single PCB meaning that they can mostly be manufactured using a PCB fabrication and assembly service (besides mounting into an enclosure which often uses injection moulding).

Automotive modules

The adoption of electronics in modern automotive vehicles has become so great that modern cars are now more electronic than mechanical. In fact, this couldn’t be truer with the introduction of EVs, which rely heavily on power converters, energy storage technologies, and complex computational devices that can monitor conditions around them via cameras in real-time. The complexity of these devices and the need for accuracy makes PCB fabrication and assembly services highly applicable, especially when using services that conform to ISO 9001 and ITAR regulations.

Wearable devices

While the wearable industry is still in its infancy, the numerous technologies offered by modern fabrication services allow wearable devices to take advantage of flexible PCBs, flat cable assemblies, and direct chip-to-board bonding. Such technologies are essential for future wearable devices as wearable devices will only be comfortable if they can move and change shape with the wearer, and this is simply not possible with standard FR4-type PCBs (the most common type in the industry). Flexible PCB technologies also help to reduce fatigue and cracking solder joints which normally occurs when PCBs are exposed to mechanical stresses such as bending, vibration, and impacts.

PCB fabrication & assembly FAQs


What is a PCB substrate?

The substrate of a PCB is the electrically insulative material that forms the base of the PCB, which copper traces sit on top of. The most common substrate PCBs use is 1.6mm FR4 fibreglass which consists of glass fibres weaved together and bonded using epoxy. However, this is starting to change with the increasing layer counts, and 4-layer PCBs are quickly becoming the norm (these, again, are 1.6mm but use thinner fibreglass layers to allow for additional copper layers).

As the substrate plays a significant role in the electrical properties of the PCB (such as capacitive and inductive effects), high-speed designs will sometimes be required to use different dielectrics. In some extreme cases, this can require the use of ceramics and other materials that have extremely controlled characteristics. In addition to fibreglass and ceramics, flexible PCB substrates are becoming available, which allow circuits to have a high-degree of flexibility. These substrates are particularly useful in applications exposed to strong mechanical vibrations and shock as they are able to resist fatigue and stress-induced fractures.


What advantages does PCB fabrication and assembly offer?

By far, the biggest advantage of PCB fabrication and assembly services is the entire construction and testing of a circuit board. Instead of needing to source services for each stage of the manufacturing process individually, our PCB fabrication and assembly combines everything into a single streamlined process.

In addition to our digital manufacturing capabilities, our PCB fabrication and assembly services eliminate the need for manual soldering of components which can be extremely difficult if SMT parts such as BGA and MLF are being used. Furthermore, the use of automation to manufacture circuits frees up valuable engineering time that can be better used for programming, testing, and troubleshooting designs.


What are the main types of testing in PCB fabrication and assembly?

When it comes to testing PCBs, numerous options exist for engineers, all of which have their own advantages and disadvantages. During the manufacturing stages, automatic optical inspection (AOI) is used to confirm the build quality of circuits rapidly. While AOI cannot observe a PCB in its entirety (it is possible but expensive), taking images of a PCB at random locations allows a machine to quickly compare what it is observing with a database of what it should see, and from there, can identify anomalies very quickly.


Does Ponoko ship worldwide?

As we heavily leverage cloud-based technologies, we can provide PCBA services to customers worldwide. Our manufacturing facilities are located around the globe, meaning that we can source components locally (thanks to our distribution partners being worldwide), ensuring rapid manufacturing times and quick delivery.


How can designers help the PCB assembly process?

The most important step that engineers need to take when submitting design files is to check that their designs conform to our PCB fabrication and assembly capabilities. As such, designers should pay extra attention to trace widths, trace spacing, and drill sizes. In addition to this, also consider the space between traces and the edge of the PCB, component courtyards, and minimum feature sizes for component legend items.

To help reduce manufacturing times and improve supply chain security, designers should use components that are as generic as possible. For example, SMD capacitors and resistors are manufactured by hundreds of companies worldwide, and the ability for a design to use any of these generic components presents serious economic advantages as well as simplifying the component curation step.
