Our Quality Control Process for Mexico PCB Assembly
- Incoming Material Inspection (IMI): We inspect all incoming materials for source defects. Components are verified for authenticity, solderability and specification compliance. PCB boards undergo pad integrity, oxidation and impedance checks, with all materials cross-checked against BOM lists to ensure no defective parts enter production and support stable Mexico PCBA processes.
- First Article Inspection (FAI): We inspect the first unit of each batch before mass production. Aligned with IPC-A-610 standards, we verify solder quality, component placement and process parameters. All data is documented to confirm design consistency and avoid batch errors for efficient PCB assembly in Mexico.
- In-Process Inspection (IPQC): We implement real-time monitoring and random sampling during production. For SMT, we control stencil alignment (±0.1mm) and reflow slope (≤3°C/sec); for THT, we check soldering time (≤3s) and fill rate (≥95%). Humidity (40%-60% RH) and ESD protection (≤100V) are checked regularly to detect deviations early.
- Finished Product Testing (FQT): We perform visual, electrical and reliability tests to qualify products. IPC-A-610 Level 2/3 visual inspection, ICT and FCT are conducted. Medical and automotive products get additional -40°C~85°C thermal cycle and vibration tests to meet high-reliability demands of PCB assembly service in Mexico.
- Rework & Re-inspection: Unqualified products are marked and isolated immediately. Our certified technicians analyze causes and execute targeted rework. Post-rework products undergo FQT again, with data recorded to ensure only qualified products move forward and complete the quality loop.
- Full-Lifecycle Traceability: We use MES systems to record component batches, production details and test results. Each Mexico PCBA product gets a unique code for rapid issue localization, full tracking and continuous improvement support, aligning with ISO 9001 and industry compliance.
