Complete PCB solutions contour

From design and DFM to assembly, test and shipment — in one contour.

Design / layout

Engineering support for schematic and layout within the project contour — support scope is agreed per project.

DFM / DFMA

File manufacturability review before launch; review terms are scoped per project.

PCB manufacturing

Rigid multilayer boards, HDI as a capability direction, finishes and materials.

Assembly

SMT / DIP / mixed, BGA context, Turnkey / Kitted / Hybrid modes.

Component purchasing

Purchasing and kitting by BOM for assembly.

Assembly test

SPI, AOI, X-Ray, FCT — as available processes.

Logistics

Packaging and shipment; shipping terms are agreed per project.

Technical consultation

Project support: materials, stack-up, kitting modes.

PCBA assembly

PCB Assembly

PCBA — the core of contract assembly

SMT, through-hole, mixed technology, BGA context and in-line process control.

  • SMT + DIP / mixedSurface-mount and through-hole in one project contour.
  • Turnkey / Kitted / HybridFull, partial kitting, or consignment.
  • ControlSPI → AOI → X-Ray → FCT as available competencies.
  • High-mixFits low/medium volume and NPI alongside series.

PCB Manufacturing

PCB manufacturing

Board types, materials, DFM, prototype→volume path. Layer and line/space limits are confirmed per project.

  • Single / double / multilayer; HDI as a capability direction
  • Rigid-Flex / FPC — on a separate service line
  • Materials: FR-4, high-TG, aluminum, Rogers / Isola / Taconic and others (examples, not exclusive)
  • Surface finishes: ENIG, OSP, immersion silver/tin…
