PCB manufacturing is not as simple as general injection molding or fabrication. Complex PCB require even more expertise.
A PCB is made through many complicated steps. Every step, from preparing the copper pieces to laminating, must be done carefully. So it’s not easy to start that kind of business, even with enough money. You need the right knowledge, skilled experts, and very accurate tools.
For this reason, when you choose a PCB manufacturer, you must consider a few factors. Not every factory can produce complex boards. These projects need the right machinery, proper investment, and technical knowledge.
Understanding Complex PCB Manufacturing
Complex PCBs are not like regular ones. If you open older electronics, you can find single-layer boards with THT components. Their connections are pretty simple, and those boards need lots of pins.
However, modern electronics depend on SMDs. These components are smaller, so you can fit many on a single board. For modern electronics, a single-layer PCB can’t meet demand. As a result, the PCB industry has adopted multi-layer and complex PCBs. How can you identify a complex PCB? Here are some common examples.
HDI, or high-density PCBs, typically use very fine copper traces. They need tiny holes called microvias. These PCBs are multilayered and usually have 8, 12, 16, or more layers. These boards also require layer alignment, lamination, and drilling.
Flexible PCBs can bend without damage. They are specially designed for repeated movement. You can see their use in foldable devices, like foldable mobiles or tablets. Rigid-flex PCBs are also in this list. They combine rigid and flexible sections on a single board.
If your industry is about telecommunications, you might need high-frequency PCBs. They are used in RF and communication devices. These boards require careful signal routing to maintain signal quality. At the same time, these boards need fine-pitch SMDs, BGAs, and micro-BGAs.
Overall, complex PCB manufacturing requires advanced equipment and precise circuit design. To ensure the final quality, strict quality control is always needed.
De beste PCB-fabrikanten voor complexe printplaten
Choosing the right manufacturers for your project can be tricky. Especially if you are a beginner, it can take time to find a reliable factory. The following five pcb manufacturers for complex boards are the best of the best in the market.
#1 UETPCB: In-House PCB Production Facility
UETPCB is a China-based PCB manufacturer. The company has experience in manufacturing all types of PCBs. They handle not only simple projects but also complex, project-based manufacturing. You only need to explain what you want to make, how it should work, and where you will use it. UETPCB can handle the rest, from design to manufacturing and assembly.
UETPCB began in 2005 as an SMT factory. In 2012, it acquired its own PCB factory. Later, it expanded into international markets. Today, UETPCB operates a vast manufacturing facility covering more than 5,000 square meters.
UETPCB manufactures a wide range of PCBs. They specialize in multi-layer PCBs, HDI, flexible, and rigid-flex PCBs. They can create 8, 12, 16, or more layers. They also provide SMT, THT, and BGA assembly services. If you need high-Q components or other types, UETPCB can help you with proper component sourcing.
Besides manufacturing, UETPCB offers PCB design, R&D support, and technical support. The company also provides pre- and after-sales support. Overall, UETPCB is an excellent choice for low-, medium-, and large-scale production. They produce PCBs for all industries, especially for automotive, electronics, medical, and telecommunications.
#2 Sierra Circuit
Sierra Circuits is a USA-based PCB manufacturer. The company produces various types of complex PCBs. They produce rigid-flex, ultra-HDI, and other advanced circuits. The company also provides PCB assembly, component sourcing, and other testing services.
The company mainly serves a wide range of industries. Its core markets are automotive, aerospace, telecommunications, and electronics.
SC is a good choice for complex and custom PCB manufacturing. However, its prices are much higher than those of China-based factories. Shipping, tariffs, and other costs can also increase the final price. Besides, SC is not suitable for low- to medium-volume orders.
#3 PCBWay
PCBWay is another China-based PCB manufacturer. One of its main benefits is its online ordering system. You can upload your PCB design, get a quotation, and place an order easily.
For example, you can order 10 simple PCBs for around $5. The company also offers custom PCB manufacturing at affordable prices. Based on the specifications mentioned, it supports up to 14 layers and a 2.4 mm board thickness.
However, it may offer limited project-based manufacturing, R&D, and technical support. PCBWay is mainly suitable for simple and medium-complexity PCB projects. It is also a good option for customers looking for affordable prices and short lead times.
#4 JLCPCB
JLCPCB is another China-based PCB manufacturer. Its services are quite similar to PCBWay. You can upload your PCB design online, review the specifications, and place an order.
One of its biggest advantages is its affordable pricing. For example, you can order five PCBs for around $2. The company also supports complex PCB manufacturing. You can select up to 32 board layers and thicknesses greater than 2.4.
However, JLCPCB may not be the best choice for complete project-based manufacturing. If your project requires extensive R&D and ongoing support, UETPCB may be a better option.
#5 OKI Circuit
OKI Circuit Technology is a Japan-based PCB manufacturer. The company is known for high-end and complex PCB manufacturing. Similar to other manufacturers, OKI produces a wide range of complex PCBs. It also offers a range of PCB manufacturing services.
However, its advanced manufacturing services may cost more. If you are looking for affordable PCB production, it may be less suitable. Complete project-based manufacturing may also involve technical challenges.
Expert Advice
Carefully vet a complex PCB manufacturer before you choose them. As mentioned, not all suppliers can make complex PCB. Some suppliers claim to be factories, but they source PCBs from other companies. The main problem is a lack of expertise. This creates communication delays, especially for after-sales support.
- Check the machinery available in the factory. What is the maximum PCB layer count they can handle? How many machines and employees are available?
- Check which quality standard the factory follows. Make sure they have proper quality-checking devices, a control process, and relevant certificates.
- Find out whether the manufacturer has its own engineering team. Check their expertise and R&D facilities.
- Confirm their production capacity and estimated lead time. Make sure they can actually handle your required quantity.
- Finally, compare the total costs carefully. Working directly with a manufacturer typically helps reduce hidden third-party costs.
