PCB and Assembly Manufacturer – QFPCB
Founded in 2009, QFPCB has grown to become one of the largest and most experienced PCB manufacturers in China. We are proud to provide you with high-quality PCB services that meet your unique needs. With more than a decade of experience in developing, manufacturing, assembling and testing custom printed circuit boards, we are now able to provide a full range of services, from rapid PCB prototyping, circuit board manufacturing, PCB assembly to component sourcing services, all with guaranteed quality and affordable prices.
We have three large factories, one for rapid PCB prototyping, one for PCB assembly, and another for large-scale PCB production, all with full manufacturing capabilities and experienced engineers and technicians. Fully compliant with ISO 9001:2015 quality management system, UL certified, and committed to complying with the most stringent manufacturing and assembly standards.
Your Trusted PCB Assembly Partner
QFPCB provides reliable PCB assembly services, catering to both quick-turn prototypes and high-volume production runs. There are no minimum quantity restrictions, and prototype assembly can be completed as quickly as within 24 hours. We adhere to RoHS and ISO standards in our production process.
For new product introductions, rapid prototyping needs, and high-volume PCB assembly, we deliver full turnkey solutions. Our factory is equipped with advanced machinery that meets nearly all industry standards. We provide SMT assembly, through-hole assembly, and mixed assembly, and are capable of assembling rigid, flexible, and rigid-flex PCBs.
Furthermore, our team can assist you with component replacements to address obsolete or unavailable parts. We also conduct DFM reviews to ensure continuous product improvement.
Component Sourcing for PCB Assembly
You may choose to provide the components yourself, particularly if you need proprietary parts for devices specific to your brand or protected by a patent.
However, for many projects, clients entrust our experienced assembly teams with component procurement. At QFPCB, we accommodate both approaches—whether it’s a prototype or a full production run. We frequently work under strict non-disclosure agreements when using client-supplied components, but we are equally adept at planning and sourcing the optimal component selection for your needs.
If you prefer the latter, we can negotiate bulk pricing agreements within your budget parameters. With over a decade of industry experience, we maintain strong connections within the dynamic technology supply chain, ensuring efficient procurement processes.
Flexible Volume PCB Assembly Service
Our PCB assembly services go above and beyond what the average PCB assembly company will do. We offer a variety of flexible circuit board assembly services for the different stages of your product development, including:
- Prototype PCB Assembly: See how well your PCB design works before generating a large order. Our quality prototype PCB assembly allows us to deliver a quick prototype, so you can identify any potential challenges in your design fast and optimize the quality of your final boards.
- Low-Volume, High Mix PCB Assembly: If you require a number of different boards for specialized applications, QFPCB is your company.
- High-Volume PCB Assembly: We are equally as skilled at cranking out large PCB assembly orders as we are at delivering small ones.
- Consigned & Partial PCB Assembly: Our consigned PCB assembly services meet IPC Class 2 or IPC class 3 standards, are ISO 9001:2015-certified and are RoHS-compliant.
- Full Turnkey PCB Assembly: Also ISO 9001:2015-certified and RoHS-compliant, our turnkey PCB assembly allows us to take care of your entire project from start to finish, so you can step in and start taking advantage of the finished product right away.
From SMD to through-hole and mixed PCB assembly projects, we do it all, including free Valor DFM/DFA checks and function testing to verify the quality of your boards, with no minimum cost requirements or added tooling charges when you reorder.
Our PCB Assembly Process
- Order Confirmation: Our team will confirm your order details and ensure all necessary files are present.
- Stencil Creation (Optional): If your project requires it, we will manufacture a SMT stencil.
- Machine Programming: Utilizing the BOM and Centroid file, we program our machines before your materials arrive. Any discrepancies within the files will be addressed promptly.
- Kit Audit: Upon receiving all materials, our team conducts a thorough inventory check. We will address any discrepancies or raise further questions at this stage. Please note, all inquiries must be resolved before assembly can commence.
- Lead Time Commencement: To allow sufficient time for the kit audit, the assembly lead time begins the next business day if all materials arrive before 12 PM PST. Materials received after this time will be processed the following business day.
- SMT Assembly: Automated equipment precisely places SMT components onto the board. The initial board undergoes a rigorous QA check to ensure accurate part placement and polarity. As boards exit the reflow oven, they undergo visual and AOI scrutiny.
- BGA Verification: We X-ray BGA components to guarantee precise placement and identify any solder bridges.
- Cleaning: If applicable, boards undergo a thorough cleaning process after SMT assembly.
- Thru-Hole Component Insertion: Depending on your project’s quantity and design, thru-hole components are either manually inserted and soldered or placed using a selective soldering machine.
- Secondary Cleaning: Following thru-hole assembly, boards may undergo another cleaning cycle if necessary.
- Final Quality Inspection: A comprehensive final inspection ensures the quality and functionality of your assembled boards.
- Packaging and Shipping: We carefully package your completed circuit board assemblies and any remaining materials for shipment. You will receive a tracking number via email to monitor your package’s journey.
