Engineering file review
Gerber files, drill data, outline, layer stack, material, finish and special notes are checked for manufacturing readiness.
Manufacturing Process
PCB manufacturing workflow from engineering review to final inspection.
YBCPCB presents a factory-oriented process for professional PCB buyers who need clear production steps, inspection checkpoints and file preparation guidance before sending a manufacturing inquiry.
Inner layer process
Inner copper layers are imaged, developed and etched before inspection and lamination preparation for multilayer PCB projects.
Lamination
Core, prepreg and copper foil are stacked and pressed according to the approved layer structure and board thickness requirement.
Drilling
Through holes, vias and slots are drilled according to the drill file, with tool selection reviewed against board thickness and copper weight.
Plating
Hole walls and outer copper are plated to build electrical connection between layers and prepare the panel for outer layer imaging.
Outer layer imaging
Photo imaging, developing and etching create the outer copper circuitry before solder mask and finish operations.
AOI inspection
Automated optical inspection checks copper features for opens, shorts, spacing issues and pattern defects during production.
Surface finishing
HASL, Lead Free HASL, ENIG, OSP or Immersion Silver is selected according to assembly method and application requirements.
Final inspection
Electrical testing, visual inspection, dimensional checks and packing review are completed before shipment preparation.
Factory Evidence
Manufacturing visual sections prepared for real factory media.
These sections reserve professional placements for verified factory photos, production equipment, inspection equipment and PCB samples.
Factory photos
Production floor and panel handling images can be added when verified media is available.
Production equipment
Imaging, drilling, plating, lamination and routing equipment sections support factory credibility.
Inspection equipment
AOI, electrical testing and visual inspection areas show process control for PCB buyers.
PCB samples
Representative boards can help buyers understand multilayer, HDI, flexible and rigid-flex capabilities.
| Workflow stage | Manufacturing focus | Buyer review point |
|---|---|---|
| File review | Gerber, drill, outline, stackup, material and finish notes | Confirm complete manufacturing data before production planning. |
| Build process | Inner layer, lamination, drilling, plating, imaging and solder mask | Match process route to layer count, copper weight and board thickness. |
| Inspection | AOI, electrical test, visual inspection and final documentation | Align quality checkpoints with application and delivery requirements. |
