01
Incoming Material
Verify incoming PCBs, electronic components, and production materials against approved specifications, BOM requirements, and supplier records before entering manufacturing.
Quality Control
Quality Control from PCB Process to Final PCBA Release
Quality control is built into each production checkpoint. We review PCB fabrication outputs, incoming materials, assembly process quality, test readiness, functional performance, and delivery documentation before products move forward.
- PCB Process Inspection
- AOI / Electrical Test
- Incoming Material Control
- SMT / THT Process Control
- ICT / FCT Support
- Traceability Reports
PCB Flow Chart
PCB Manufacturing Quality Checkpoints
Based on the PCB process flow, each key manufacturing stage can be checked for image quality, etching quality, lamination stability, drilling accuracy, plating quality, solder mask condition, final finish, routing, electrical performance, and final inspection readiness.
01
02
PCB Fabrication
Control PCB manufacturing quality through layer alignment, drilling, copper thickness, surface finish, and electrical performance verification to ensure reliable board production.
03
Assembly Process
Monitor SMT and THT assembly processes to maintain component placement accuracy, soldering quality, and stable production performance.
04
Inspection
Perform automated and visual inspections to identify assembly defects, solder issues, component errors, and process deviations during manufacturing.
05
Testing
Validate PCB functionality and electrical performance through appropriate testing methods to confirm product reliability before shipment.
06
Records & Traceability
Maintain complete manufacturing records, inspection data, test results, and material information to support product traceability and quality control.
07
Final Quality Review
Complete final quality review, documentation confirmation, packaging checks, and shipment approval before products are released for delivery.
08
Continuous Improvement
Analyze quality data, identify root causes, and optimize manufacturing processes to improve yield, consistency, and long-term product quality.

Any Questions?
Start Your PCB Assembly Project
How is quality controlled during production?
Quality control covers incoming materials, bare PCB inspection, SMT and THT assembly, testing, final inspection, and packing. Key requirements are confirmed before production and checked at the relevant stages.
Which inspection and testing methods are used?
The inspection plan depends on the board design, component packages, product function, and quality requirements. It may include SPI, AOI, X-ray, ICT, functional testing, and final visual inspection.
What happens if a quality issue is found?
We review the affected materials, process records, and inspection results before production continues. If corrective action or your confirmation is required, we will discuss it with you first.
What quality records can be provided?
Depending on the agreed requirements, records may include incoming inspection results, AOI data, X-ray images, ICT or functional test results, final inspection records, and batch traceability information.
