TURNKEY PCBASSEMBLY PROCESS?
Getting familiar with the process can help you understand what to expect and how it works.
1. Design Review and File PreparationBefore production begins, we conduct Design for Manufacturing (DFM) checks to ensure the PCB is optimized for efficient and cost-effective assembly. We require essential design files, including Gerber, ODB++, BOM, NC drill, and pick-and-place files. A thorough design review helps detect manufacturability issues early, avoiding costly delays.
2. Component Sourcing and ProcurementWe handle component sourcing by selecting parts based on the BOM, balancing cost, availability, and lead time. Standard components speed up production, while hard-to-find parts may extend timelines. Our trusted supplier network ensures quality parts at competitive prices, helping reduce procurement risks and costs.
3. Material PreparationBefore assembly, we inspect and verify all components and materials to prevent defects. This includes checking for damage, ensuring part compatibility, and verifying inventory levels. Proper preparation ensures smooth production, reduces rework, and enhances final PCB quality by eliminating material-related issues.
4. PCB FabricationOnce materials are ready, we begin PCB fabrication, which includes layer stacking, etching, drilling, solder masking, and surface finishing. We also perform quality control checks throughout the process to detect structural or electrical defects. This step ensures the PCB meets design requirements before assembly.
5. Assembly (SMT & Through-Hole)During assembly, we use Surface Mount Technology (SMT) for high-speed, automated component placement. Through-hole assembly is used for components requiring stronger mechanical bonds. Both methods involve soldering, quality inspections, and reflow processes to ensure secure connections and structural integrity.
6. Inspection and TestingTo maintain high standards, we conduct multiple inspection and testing methods, including AOI, X-ray, ICT, flying probe, and functional testing. These tests identify potential defects before shipment, ensuring reliability, electrical performance, and compliance with industry quality standards.
7. ProgrammingFor PCBs requiring embedded software or firmware, we program microcontrollers, FPGAs, and other ICs to perform their intended functions. Common applications include smart devices, medical equipment, and industrial automation, ensuring seamless integration and device functionality.
8. Conformal CoatingTo protect the PCB from moisture, dust, and extreme conditions, we apply a thin conformal coating after assembly. This enhances durability, reduces environmental damage, and extends the PCB’s operational lifespan, especially for harsh environments or mission-critical applications.
9. Final Inspection and PackagingBefore shipping, we perform a final quality check to ensure the PCB is defect-free, fully functional, and meets customer specifications. Boards are packaged in antistatic bags, vacuum-sealed, and moisture-protected to prevent damage in transit, ensuring safe and reliable delivery.
What is the Cost of Turnkey PCB Assembly?
The cost of turnkey PCB assembly varies significantly based on several factors. For a rough estimate, the cost of manufacturing a printed circuit prototype ranges from $10 to $50, depending on size, material, and production labor costs. Assembly costs per square inch can range from $0.02 to $0.05, influenced by necessary assembly labor, labor rates, assembly time, overhead manufacturing expenses, and board design complexity.
