Equipment for PCBA Manufacturing
At FS Circuits, we’ve invested heavily in the best equipment to enable us to deliver top-notch quality PCB assembly services:
- 8 SMT Production Lines – With the capability to hold components as small as 0201 (01005) and fine-pitch BGA packages with a minimum of 0.15mm mounting
- 2 THT Production Lines – For conventional through-hole component assembly
- 10-Zone Reflow Soldering System – To allow precise temperature control for the optimal soldering result
- 3D SPI, X-Ray, and AOI Equipment – For thorough inspection and quality control
- Wave Soldering Machines – For efficient through-hole assembly
- Automated and Semi-Automated Testing Systems – For end-to-end functional testing
Our turnkey PCB assembly service simplifies your electronics manufacturing process by providing a complete solution from design to finished product. This approach eliminates the need to coordinate multiple vendors, saving you time, reducing costs, and ensuring consistent quality throughout the production process.
For each project, we assign a dedicated project manager who oversees every aspect from order placement to production, testing, and shipping. This ensures clear communication and accountability throughout the manufacturing process.
- Superior Material Stability: Our PCB materials demonstrate high dimensional stability, with board curvature under 0.75%, minimizing deformation and warping. Enhanced copper adhesion ensures no layer draping or delamination under high temperatures.
- Enhanced Copper Plating: We exceed IPC Class 2 standards with via copper thickness ranging between 18-20μm, reducing the risk of copper shedding in high-current scenarios.
- High-Quality Soldermask: Our solder resistance meets the stringent 8-30μm standard, offering strong adhesion and minimizing soldering defects, ensuring high PCB reliability.
- Advanced Surface Treatment: We strictly control surface treatment within IPC standards to prevent issues like black nickel or abnormal nickel thickness during operation.
- Premium Component Sourcing: We use original components and premium brands, like ABC-ATEC inductors, to ensure longevity and stable performance, outperforming domestic brands.
- Precision Assembly: With industry-leading SMT technology, we ensure accurate placement and soldering, reducing BGA soldering risks and ensuring high product yield.
- Stringent Quality Control: Our thorough inspection processes, including AOI and X-ray, guarantee that all products meet or exceed customer specifications.
- Robust Packaging: We utilize custom anti-static, moisture-proof packaging to ensure safe delivery, with multiple safeguards against shock and compression damage.
