Our PCB Assembly Quality Control Process
- Incoming material inspection: 100% screening of components against BOM lists and IPC-A-610 standards, combining X-ray detection, high-magnification visual inspection, and electrical testing (LCR measurement). We verify component values, specifications, and integrity to eliminate oxidation, damage, or counterfeit parts before warehouse storage, laying a solid foundation for PCB assembly Thailand quality.
- In-process inspection: Conducts fixed-point checks every 2 hours at printing, mounting, and soldering stages, paired with random sampling reviews. MES system synchronously logs all data, including solder paste thickness, component placement accuracy, and soldering parameters, triggering real-time alerts for anomalies to enable immediate correction and prevent batch defects.
- Finished product testing: Integrates ICT (circuit continuity testing), FCT (functional performance verification), and X-ray tomography. This covers 100% of hidden soldering defects (e.g., voids, cold joints) and validates product performance against design requirements, ensuring consistency for high-precision Thailand PCB assembly applications.
- Traceability system: Full-lot tracking from raw materials to delivery via unique batch codes. Records include component supplier info, production station, testing data, and operator details, enabling rapid root-cause analysis for any issues. This meets strict compliance requirements for medical, automotive, and aerospace industries, reinforcing accountability.

Case Studies of Our Medical PCB Assembly Thailand
Project Background: A Thai-based medical device company specializing in portable diagnostic equipment sought a reliable Thai PCB assembly partner for its newly developed blood analyzer. The analyzer was designed for primary healthcare facilities and mobile clinics. Project requirements included strict adherence to ISO 13485 standards, material biocompatibility (to avoid adverse reactions upon contact with the human body), and compliance with the Thai Food and Drug Administration (TFDA) medical device regulations.
Project Requirements: Precision assembly of 01005 size micro-components (core sensors and connectors), a yield rate of over 99.95% to ensure clinical reliability, a 15-day delivery time for 5000 units (to meet the deadline for a Southeast Asian medical exhibition), and batch-level comprehensive traceability for TFDA submission, including component origin and production parameters.
Challenges: Shortage of locally available FDA-certified medical-grade connectors and micro-sensors, requiring 2-3 weeks for international procurement; tight delivery schedule conflicting with traditional prototyping cycles; ensuring solder joint void rate (≤3%) and impedance stability (±5%) to prevent signal interference during clinical use.
Solution: We leveraged our global supply chain to source FDA-certified components from pre-certified European suppliers, completing delivery within 72 hours. 24-hour prototype production was initiated for design verification, combined with MES-driven process control to monitor solder paste thickness (0.12-0.15mm) and placement accuracy (±0.02mm). Free DFM analysis was provided to optimize component layout, avoid heat concentration areas, and improve impedance consistency.
Project Results: A yield rate of 99.98% was achieved (only 10 defective units out of 5000), with delivery completed 3 days ahead of schedule (total 12 days). Clinical trials confirmed 100% signal stability and no biocompatibility issues; TFDA traceability documentation was approved on the first submission. The client expanded the scope of cooperation, designating us as the exclusive Thai PCB assembly supplier for two new product lines (portable ultrasound equipment and blood glucose meters).
