China PCBA PCB Assembly Pain Points from Customers
- Quality Control Issues
- Supply Chain Management
- Soldering Process Challenges
- Production Efficiency & Lead Time
- Information & Data Management
- After-sales Service Response
| Category | Specific Issues |
|---|---|
| 1. Quality Control Issues | – Component misalignment, soldering defects, open or short circuits at solder joints – Unstable raw material quality reduces overall product reliability – Manual operation errors lead to batch-level quality problems |
| 2. Supply Chain Management | – Material shortages and delivery delays affect production schedules – Raw material price fluctuations make cost control difficult – Over-reliance on a single supplier creates supply chain vulnerability |
| 3. Soldering Process Challenges | – High failure rate in BGA component soldering – Fine-pitch pads in high-density layouts are hard to solder – Inaccurate temperature control leads to thermal stress failures |
| 4. Production Efficiency & Lead Time | – Traditional manufacturing methods are inefficient and slow – Manual paneling, dispensing, and other steps are time-consuming and error-prone – Lack of lean production mindset leads to wasted resources |
| 5. Information & Data Management | – Complex production processes with poor traceability – Slow data collection makes real-time monitoring difficult – Troubleshooting takes time due to limited traceability |
| 6. After-sales Service Response | – Long and complicated after-sales processes – Difficult to locate problems due to weak data tracking – Lack of a closed-loop system reduces problem resolution efficiency |

Quality and Certifications
- Certified & Compliant Standards: ISO 9001, ISO 13485, IATF 16949, AS9100D Certified, and UL, REACH, RoHS Compliant
- 100% Flying Probe Test – Verifies electrical connectivity for prototype or low-volume PCBs without needing a fixture.
- 100% AOI (Automated Optical Inspection) – Full inspection of components and solder joints for placement accuracy, polarity, bridging, tombstoning, and missing parts.
- X-RAY Alignment Inspection – Checks hidden solder joints (e.g., BGA, QFN) for misalignment, voids, and bridging.
- Impedance Testing – Ensures controlled impedance traces meet design specifications, critical for high-speed signal transmission.
- ICT (In-Circuit Test) – Detects manufacturing defects such as shorts, opens, component values, and soldering faults.
- Functional Test (FCT) – Simulates real working conditions to verify the entire assembled board functions as intended.
- SPI (Solder Paste Inspection) – Measures solder paste volume, height, area, and alignment before placement.
- First Article Inspection (FAI) – Confirms all components are correctly placed and values are within tolerance before mass production.
- Aging Test / Burn-in Test – Stresses the assembled boards under high temperature/load to identify early failures.
- ESD Testing – Ensures boards are protected against electrostatic discharge during and after assembly.
- Visual Inspection – Manual quality check for cosmetic and mechanical issues not easily captured by machines.
- Continuity and Short Circuit Test – Verifies that there are no unwanted connections and all circuits are properly closed.

FAQs
- Q: What is the minimum stencil thickness you can make?
A: 0.06mm, 0.08mm, 0.10mm, 0.12mm. - Q: What is the recommended warming time, mixing time, and storage temperature for solder paste?
A: The solder paste should be warmed to room temperature for about 4 hours before use. It needs to be mixed or stirred thoroughly for approximately 3 minutes to ensure uniform consistency. For storage, the solder paste should be kept refrigerated at a temperature between 2°C and 10°C to maintain its quality and shelf life.
