Quality Control

PCB quality control for reliable manufacturing programs.

YBCPCB explains its quality control workflow for overseas engineers and procurement teams, from incoming inspection to final board review.

Incoming inspection

Materials, copper clad laminate, process supplies and customer files are reviewed before production release.

Inner layer AOI

AOI inspection helps identify open circuits, short circuits and pattern defects before multilayer lamination.

Process inspection

Drilling, plating, solder mask and surface finish stages include checks aligned with the approved production route.

Electrical testing

Finished PCB panels are tested according to netlist and customer requirements to confirm electrical continuity.

Visual inspection

Inspectors review solder mask, silkscreen, surface finish, board outline, contamination and handling marks.

Reliability testing

Project-specific reliability testing can be reviewed for thermal, mechanical, solderability or application requirements.

Inspection Equipment

Quality evidence prepared for buyer review.

Inspection equipment images and production records can support supplier qualification when verified materials are available. The public website keeps these sections factual and avoids unsupported factory claims.

Quality management process FAQ

What files help quality planning?

Gerber files, drill data, IPC class expectations, inspection notes, controlled impedance requirements and application information help define quality checkpoints.

Can inspection documents be reviewed?

Available inspection documents can be reviewed during inquiry and supplier qualification when verified records are prepared.

How does quality control connect with capability review?

Capability review confirms whether layer count, copper weight, thickness, finish and inspection needs can be aligned with the production process.
