Factory & manufacturing process

See how an RFQ becomes a production plan.

Process routes vary by board construction. This page shows the review and manufacturing stages that may apply, together with clearly labeled company-supplied photographs and representative product visuals.

Manufacturing route

The route starts with the actual data.

No single process flow applies to every board. Layer count, material, via structure, copper, impedance, surface finish, testing and volume determine which stages and controls are required.

Data intake

Gerber or ODB++, drill data, fabrication notes, stack-up and quantity are checked for completeness.

CAM and DFM

Manufacturability, copper distribution, drill relationships and required tolerances are reviewed.

Stack-up and material

Construction, laminate, copper, finished thickness and controlled features are aligned.

Inner-layer processing

Imaging, etching and inner-layer inspection are routed according to the construction.

Lamination

Layer build, material behavior and sequential requirements are controlled for the agreed route.

Drilling or laser processing

Mechanical holes, microvias and related preparation are selected from the released data.

Plating and outer layers

Hole-wall and pattern formation controls are applied for the specified copper construction.

Solder mask and finish

Mask, legend and surface finish are produced to the fabrication specification.

Test and inspection

Electrical test and any specified impedance, microsection or other verification are completed.

Release and packing

Final inspection, project records and packing requirements are checked before shipment.

Company-supplied on-site video

Factory in motion.

Three short, silent clips show the production environment, automated panel handling and inspection workstations. They are presented as on-site visual evidence; equipment model, quantity and process scope are confirmed separately during technical review.

Company-supplied photographs

Factory imagery, labeled by source.

These photographs were supplied with the website project as factory imagery. Equipment model, count and calibration records are confirmed separately during technical or supplier review.
