PCBasic is located in Shenzhen, China. It is a professional manufacturer specializing in rapid PCB prototyping, assembly (PCBA), and small-batch production.
We have 9 fully automatic SMT assembly lines and are equipped with advanced devices such as AOI, 3D X-ray inspection and flying probe testing to ensure the high quality of each circuit board.
The following is an introduction to the main PCB manufacturing capabilities of PCBasic. Here you can learn about the types of materials we can process, manufacturing processes, product categories, as well as the dimensional accuracy and process tolerances we can achieve.
Our PCB services are divided into two major types:
This includes small-batch, fast-delivery circuit boards, custom specification standard PCBs, and fast-order PCBs (Gerber file viewing supported). These services are highly suitable for the product prototype verification and pilot runs.
This represents the highest level of manufacturing capability for PCBasic, including full-specification PCBs, high-precision complex multi-layer boards, and mass production.
In some cases, certain special materials or laminated structures may be temporarily out of stock.
If your PCB requirements exceed the following capabilities, please contact our sales representative. We will provide you with professional technical support and customized manufacturing solutions.
Note: In PCBasic, "Standard PCB" refers to a comprehensive service of advanced PCB + rapid prototyping PCB, which can not only achieve high-performance manufacturing but also ensure fast delivery.

Thank you for reviewing the circuit board manufacturing capabilities of PCBasic. When you place an order online, please upload your PCB files in any of the following formats: Gerber, .pcb, .PcbDoc or .cam.
Preferred format: Gerber file (RS-274X/X2 standard).
If you only have the source files of Altium DXP/Altium Designer (.pcb / .PcbDoc), we can also generate Gerber files for you. Our engineering tools support project files of Altium Designer versions 23.x and 10.x. Please try to avoid using versions higher than AD 23.x / 10.x to ensure full compatibility of the files.
You can also send the files directly to your PCBasic sales representative, but we strongly recommend that you place an order and upload the files online through the website. This way, you can enjoy a faster processing speed and complete traceability.
We offer circuit board manufacturing services from prototype to mass production for mission-critical electronic products, ensuring high reliability and consistency. Customers choose PCBasic because we have a fast response, strict tolerance control and a stable quality management system.
Medical customers make up an important part of our customer base. PCBasic strictly adheres to a high-standard quality system, offering short delivery times and competitive prices to meet the manufacturing demands of medical equipment with extremely high repeatability and precision requirements.
Most of our orders come from these industries. PCBasic, with its advantages of rapid quoting, on-time delivery, professional engineering support and high cost-effective manufacturing capabilities, helps customers smoothly expand from small-scale verification to large-scale production.
We support students and electronics enthusiasts - they are the future innovators in technology. PCBasic has become a reliable partner for academic projects, competition projects and maker research and development by offering affordable pricing and stable quality.
If you are engaged in an educational project or team, feel free to send us the project details. We are happy to explore suitable cooperation methods for the educational support program.
