FAQ
Q1: What does electronic assembly include?
A1: It’s a comprehensive service covering three core areas: PCB assembly (SMT/THT/mixed technology), cable harness assembly (shielded/unshielded/coaxial), and box build assembly (integrating PCBs, harnesses, enclosures into finished products). It delivers end-to-end solutions from components to ready-to-ship goods.
Q2: Can China 365PCB handle both small prototypes and large-scale production?
A2: Yes, we support all volume ranges. Prototypes (1–10 units) take 3–7 days for R&D validation; low volume (10–1000 units) takes 5–12 days for pre-production; high volume (1000+ units) uses automated lines for 10–20 day turnaround – no need to switch suppliers as your project scales.
Q3: What quality controls are implemented in your electronic assembly process?
A3: We use multi-layer testing: AOI for SMT placement defects, X-ray for hidden BGA/QFN solder joints, ICT for circuit continuity, and functional testing for product performance. All processes follow IPC-A-610 standards, ensuring 99.9% defect-free assemblies.
Q4: Are your electronic assembly services RoHS compliant?
A4: Absolutely. All components (resistors, connectors, cables) are RoHS-compliant to restrict hazardous substances, and assembly processes (solder paste, cleaning) follow RoHS guidelines. We provide compliance certificates upon request for your audit needs.
Q5: What industries do you serve with electronic assembly?
A5: We serve consumer electronics (smartphones), medical devices (diagnostic gear), automotive (ECUs), industrial automation (PLCs), aerospace & defense (avionics), and telecommunications (5G base stations). Each industry gets tailored solutions (e.g., sterile finishes for medical, high-temperature parts for automotive).
