PCB Assembly Capability
As a leading PCB assembly manufacturer, WellCircuits offers comprehensive high-end PCB assembly and rapid turnaround services. We not only produce bare boards—unpopulated PCBs that serve as the starting point for the assembly process—but also efficiently source components and complete the assembly for you.
Printed circuit board assembly is the process of connecting the electronic components with the wirings of printed circuit boards. The traces or conductive pathways engraved in the laminated copper sheets of PCBs are used within a non-conductive substrate in order to form the assembly. Attaching the electronic components with the printed circuit boards is the concluding action before using the fully operational electronic device.
At WellCircuits, we offer a one-stop solution for high-end PCB manufacturing and rapid assembly services. This approach not only saves the downtime caused by transportation but also allows you to have better control over the quality of your PCBs, with all processes completed in one place. Since 2006, our experienced team has carried decades of PCB assembly expertise, deeply understanding how to realize your designs without delays or quality flaws. Ensuring 100% satisfaction with every project is our relentless pursuit. WellCircuits manages the entire process from procurement to testing and delivery, ensuring seamless integration and quality at every step.
File Requirements For Assembly
We offer SMT (surface-mount technology) and through-hole PCB assembly services, including the assembly of hole components and through hole components, suitable for both prototype and bulk orders, and can meet IPC Class II or III standards according to your requirements. Soldering quality is strictly controlled to meet industry standards, ensuring reliable solder joints and electrical performance. We provide one-stop assembly and consignment assembly capabilities, covering various types of circuit boards, including rigid PCBs, flexible PCBs, rigid-flex PCBs, RF PCBs, HDI PCBs, multilayer PCBs, and complex circuit boards. Among these, one-stop assembly accounts for the majority of our orders, as we manage the entire production process. In turnkey solutions, the assembly house procures all the materials and components needed for manufacturing, while in consignment projects, the client supplies all the materials. Our optimized production processes and use of automated machines ensure efficiency, consistency, and high-quality outputs. Assembly drawings are essential for accurate assembly, and Gerber files are required for precise PCB fabrication and assembly. The solder mask is a key PCB layer in the manufacturing process, and box build assembly integrates mechanical components for complete electromechanical solutions. Our manufacturing process includes rigorous quality control, with final inspection before delivery to guarantee defect-free products. We offer a range of assembly techniques, including manual soldering, hand soldering, and selective soldering, to suit different production needs.
Our assembly capabilities cover reflow soldering using a reflow oven, solder paste printing, precise solder paste deposits with liquid flux, and the use of surface mount pads for SMT components. We monitor for solder bridges and utilize automatic optical inspection to verify placement and detect defects, while also managing flux residues post-soldering. For through-hole assembly, we handle component leads, ensure proper solder joints on the pcb board, and use processes such as solder wave and the wave soldering process for THT components. We are equipped to assemble fine pitch components and support box build assembly with integration of mechanical components. Below is a detailed list of our capabilities.
Component Sourcing
At WellCircuits, we recognize that reliable component sourcing is the backbone of a successful pcb assembly process. Our dedicated sourcing team leverages long-standing partnerships with leading authorized distributors—including Digi-Key, Mouser Electronics, Arrow Electronics, and Avnet—to secure high-quality electronic components for every project. Whether your design calls for standard surface mount components, fine pitch BGAs, or other leadless package parts, we ensure that all the components required for your printed circuit board assembly are procured efficiently and cost-effectively.
The process begins with a thorough review of your bill of materials (BOM). Our internal online procurement system is directly linked to trusted suppliers and OEM channels, allowing us to quickly quote, source, and order even the most challenging or hard-to-find parts. In cases where certain items are unavailable, our team will proactively suggest suitable alternatives, always seeking your approval before proceeding. For customers who prefer to supply their own parts, we offer flexible consigned assembly options, while our turnkey assembly service covers the entire component sourcing and assembly process from start to finish.
Quality assurance is integral to our component sourcing workflow. Every batch of incoming components undergoes rigorous inspection, including automated optical inspection (AOI) and solder paste inspection (SPI), to detect any defects or inconsistencies before assembly begins. Components are stored in a controlled environment to preserve their integrity, ensuring optimal performance during the assembly process.
Our advanced facility is equipped with state-of-the-art automated equipment, such as high-speed pick and place machines, precision reflow ovens, and wave soldering systems, supporting both surface mount assembly and through hole assembly. This enables us to handle everything from quick-turn pcb prototypes to mass production runs, while maintaining tight control over quality and lead times.
To guarantee the reliability of your assembled boards, we employ a comprehensive suite of test methods, including functional testing, flying probe testing, and x-ray inspection. For projects requiring additional protection, we offer conformal coating and other specialized finishing services, safeguarding your circuit boards against environmental stresses.
By entrusting your component sourcing and pcb assembly services to WellCircuits, you benefit from a streamlined supply chain, reduced risk of delays, and the assurance that every part of your project meets the highest standards of quality and performance. Our expertise in component sourcing, pcb fabrication, and the entire assembly process makes us the ideal partner for OEMs in industries where precision, reliability, and speed are paramount.
Whether you require a small batch of flexible pcbs for prototyping or a large-scale production of complex multilayer boards, WellCircuits delivers a tailored, efficient assembly process that supports your innovation and growth.
