PRECISION PCB
MANUFACTURING
From engineering data to production reality.
These figures describe the simulated configuration this site is designed around. They are not measured production capability.
Change the configuration. Watch the board.
Each option changes the board's structure. This is a configuration preview, not a DFM verdict — a real manufacturability review needs the actual Gerber data.
A section through the board.
Four layers, 1.60 mm overall. Each layer is listed with its thickness, material and what it is for.

From data to board.
Scroll, and the board beside the list changes with the process: data first, then inner layers, lamination, drilling, plating, outer copper, solder mask, silkscreen, finished board.
ENGINEERING
Gerber · DFM · CAM
Engineering data arrives and is read as a set of manufacturable instructions. Layer count, trace width, spacing, drill and impedance are confirmed here.
MATERIAL
Material selection
Base material and stack-up are chosen against electrical, thermal and cost requirements, then dielectric thickness after lamination is confirmed.
INNER LAYER
Imaging · Etching
Inner layers are coated, exposed, developed and etched to form the inner copper.
LAMINATION
High pressure · High temperature
The stack is bonded under high pressure and temperature. Dielectric thickness is set at this step and does not change afterwards.
DRILLING
Mechanical · Laser
Mechanical drilling for through holes, laser for microvias. Hole position accuracy sets the ceiling for every alignment step that follows.
PLATING
Copper · Surface treatment
Barrel plating connects the layers; surface treatment follows according to the finish specified on the drawing.
AOI
Automated optical inspection
Every panel is compared optically against the CAM data to find opens, shorts and cosmetic defects.
E-TEST
100% electrical testing
A flying probe or fixture tests each board electrically, confirming continuity and isolation across every net.
FINAL QC
Inspection · Packaging
Visual, dimensional and impedance checks; passing boards are vacuum packed with their inspection record.
SHIPMENT
Traceable dispatch
Lot, material and inspection records ship with the boards and trace back to the production parameters.
The model on the right illustrates the stage. It is not a photograph of the real process.
Quality is measured.
Six checks, each answering one question. None of them samples.
Automated Optical Inspection
Every panel is compared against the CAM data; opens, shorts and cosmetic defects are caught before shipment.
100% Electrical Testing
Flying probe or dedicated fixtures test every net for continuity and isolation. No sampling.
Internal Structure Inspection
After lamination, X-ray inspection checks registration and barrel copper — the layers a camera cannot see.
Controlled Impedance
Time-domain reflectometry measures impedance and confirms controlled-impedance nets sit inside tolerance.
Cross Section Analysis
A cross section is measured under a microscope: barrel copper, dielectric thickness and etch profile.
Visual + Dimensional
Final visual, edge, hole and thickness confirmation, and the inspection record that goes with the lot.
The floor, as a system.
Equipment state, engineering progress and inspection results move along one data path.
