What we build

The assembly services you can buy from one factory.

SMT placement machine loading components at Kilandu Shenzhen PCBA factory
  • 01

    SMT assembly

    01005 chips up to BGA and QFN on our high-speed SMT lines, with AOI on every board.

  • 02

    Through-hole (DIP) assembly

    our DIP lines with lead-free wave soldering for axial and radial parts, plus hand soldering for odd-form components.

  • 03

    Box build and cable assembly

    Cables, enclosures and mechanical assembly, so the shipment arrives ready for your line rather than for your bench.

  • 04

    Turnkey (full BOM) projects

    Component sourcing from LCSC and global distributors with BOM matching and shortage alerts, so you receive a board rather than a kit.

  • 05

    Prototype and NPI

    Small quantities to validate the design and the process, with engineering support before you commit to volume.

How we build it

From solder paste to tested board, inside our own factory in Shenzhen.

1

SMT assembly

01005 chips up to BGA and QFN placed on our high-speed SMT lines and reflowed with lead-free paste.

SPI, AOI, X-ray and ICT

3D SPI verifies solder paste volume before placement, AOI inspects every board after reflow, X-ray covers BGA and hidden joints, and in-circuit test runs on fixtures built to your netlist.

Functional test against your own specification, with traceable inspection records issued for every batch.

Frequently Asked Questions

Quick answers to what buyers ask us most about this product family.

What PCBA services does Kilandu offer?

SMT, through-hole (DIP), box build, and full turnkey assembly from prototype to volume.

Do you source components?

Yes - managed sourcing from LCSC and global distributors, with BOM matching and shortage alerts.

What quality standard do you assemble to?

IPC-A-610 Class 2/3 with SPI/AOI/X-ray/ICT/FCT.

What component types and package sizes can you place?

Fine-pitch devices down to 01005 and 0.25 mm pitch, including QFN, BGA, connectors and odd-form parts. Boards from 1 to 24 layers are supported, and mixed-technology assemblies that combine fine-pitch SMT with heavy through-hole parts are handled on the same lines.

What inspection is built into the process?

Solder paste volume is verified by 3D SPI before placement, automated optical inspection runs after reflow, and X-ray is used where joints are hidden, such as BGA and QFN. Final functional test is applied where the customer specifies it, and lot-level traceability links the finished assembly to the material and process records.

Can you build a complete product rather than just the board?

Yes. Box build and final assembly are available, covering enclosure assembly, cable and harness fitting, connector and label application, and the functional test that confirms the finished unit. That lets a customer take delivery of a tested product rather than a board that still needs integration work.
