Certifications and compliance

Certificate numbers are published so your sourcing and audit teams can verify them directly.

Certificate numbers, issuing bodies and validity dates are published on the quality assurance page.

Kilandu holds IATF 16949:2016 (IATF No. 0596984; IATF USI L3A259; ZA-FCAV No. 2600270/R0S) issued by Beijing Zhong An Zhi Huan Certification Center Co., Ltd., ISO 9001:2015 (cert. CN27125Q0392R0S) and ISO 14001:2015 (cert. CN27125E0142R0S) issued by Guangdong ZQ Certification Service Co., Ltd. (CNAS C271-M), and UL File No. E352816 for assemblies covered by that file. Automotive work runs under the IATF 16949 certificate with IPC-A-610 Class 2 or Class 3 acceptance as agreed per project, and every lot ships with lot and serial-level traceability.

Automotive PCBA is manufactured under an IATF 16949 certified automotive quality management system. Certificate numbers and scope are published on the quality assurance page.

The IATF 16949 certificate covers the manufacturing of printed circuit board assemblies (PCBA) and excludes product design under clause 8.3, so design authority stays with your engineering team while process control, traceability and change management are audited to the automotive standard.

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.

2

Reflow and wave soldering

Lead-free reflow for SMT, plus our DIP lines with lead-free wave soldering for the through-hole parts.

3

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.

4

Functional test and traceability

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

What automotive work demands of the process

The three things a car programme asks for that a general industrial build does not.

An IATF 16949 quality system in day-to-day production

Automotive work is expected to run inside a registered quality management system rather than alongside one. The process plan, the control plan and the reaction plan exist for the programme, and a deviation is handled through a documented route rather than a verbal one. Our quality system is certified to IATF 16949:2016, and the records it produces are the ones issued with an automotive build rather than a separate set written for the occasion.

Traceability that survives a field return

A part that reaches a vehicle has to be answerable years later. Each automotive build carries lot-level material records, the process record for the work order and the inspection and test results for that batch, so a field return can be matched back to the material and to the process window it was built in. Where the customer's own serial scheme applies, the code on the unit is tied to that record rather than kept in a separate system.

Change control across a production life

Once a programme is in production, changes are the risk. A component substitution, a process adjustment or a tooling replacement is proposed, reviewed against the customer's approval route and recorded before it is run, so the approved configuration and the built configuration stay the same thing. Where a change is forced by a supplier end-of-life notice, it is raised early enough to be planned rather than discovered at the line.

From NPI to volume without a second qualification

Why prototype, pre-production and series builds run on one set of lines.

Automotive programmes usually start with a small number of boards and grow. Splitting the early builds and the series builds across different suppliers is what turns a ramp into a re-qualification, because the process window, the fixtures and the inspection data from the prototype are not the ones the volume build uses. Here the same SMT and through-hole lines, the same inspection regime and the same record structure run from the first prototype through pre-production to series volume.

Prototype and pre-production runs

Early builds follow the same route as production: stencil and paste parameters agreed, SPI + AOI + X-ray in process, ICT + FCT on the electrical side, and the results kept against the work order. That gives the programme a record of how the design behaved before volume, which is what a ramp decision is actually based on.

Mixed SMT and through-hole content

Automotive boards frequently carry fine-pitch controllers next to connectors, relays and other heavy through-hole parts. Both are soldered in the same factory and the same work order, so the sequence - reflow for the surface-mount side, wave or selective soldering for the through-hole content - is planned as one route rather than handed between two suppliers.

What a volume ask changes, and what it does not

Where a programme moves to higher volume, the capacity question is answered with the lines already used for the early builds. Volume changes the material plan and the fixture count, not the process or the record structure; the line list and capacity figures are on the factory capabilities page.
