PCBA applications: the industries we build for
Kilandu (Shenzhen Jintianlei Innovation Technology Co., Ltd.) is a turnkey PCBA manufacturer in Bao'an, Shenzhen, China, serving OEM customers in Europe, Russia and the Americas. We assemble printed circuit board assemblies across twelve application areas - medical and diagnostic devices, automotive electronics, industrial control, inverters and energy storage, VFD and motor drives, consumer and digital products, connected devices, EV charging, test and measurement, audio equipment, LED lighting and AI hardware - from Gerber and BOM through component sourcing, SMT, DIP, assembly and functional test.

How each application is handled
Medical and diagnostic devices
Kilandu assembles medical device PCBA for patient monitoring, diagnostic instruments, imaging and laboratory equipment. Boards are built with full material traceability and shipped with inspection records, so OEM customers can document their own quality files. Read more: Medical and diagnostic devices.
Automotive electronics
Automotive boards cover body and cabin control, infotainment, telematics, lighting and sensor interfaces. We assemble under an IATF 16949 certified system with IPC-A-610 Class 2/3 acceptance, apply conformal coating where the environment demands it, and run functional test before packing. Read more: Automotive electronics.
Consumer and digital products
Consumer and digital products need control boards, sensor nodes, gateways and connected-appliance electronics. We run mixed-technology builds (SMT plus automatic DIP) with wireless module placement, and support the whole path from prototype quantities to volume production. Read more: Consumer and digital products.
Inverters and energy storage
Inverter and energy storage assemblies include solar inverter control boards, battery management systems, power modules and EV charging modules. These are high-power, thermal-critical boards, so we combine heavy-copper layout capability with lead-free wave soldering and selective soldering. Read more: Inverters and energy storage.
VFD and motor drives
Variable frequency drives, motor controllers and industrial drive units call for high-power layout and IGBT gate drive assembly, with attention to creepage distance and thermal paths. Kilandu builds these boards to IPC-A-610 Class 2/3 and tests them on application-specific fixtures. Read more: VFD and motor drives.
Industrial control and automation
Industrial control PCBA covers PLCs, HMIs, motor drives, measurement and control boards and power monitoring units built for 24/7 operation. We select wide-temperature components, apply conformal coating, and validate with AOI and functional test. Read more: Industrial control and automation.
Connected devices and IoT
IoT PCBA spans wireless modules, sensor boards, edge gateways and smart metering. Because the boards combine RF, sensing and power management, we handle antenna-aware assembly and low-power validation alongside the usual AOI and functional test. Read more: Connected devices and IoT.
AI hardware
AI hardware PCBA includes accelerator boards, GPU and AI module carriers and other high-layer-count computing boards. These builds lean on BGA placement with X-ray inspection, fine-pitch capability and tight control of signal-integrity-sensitive routing. Read more: AI hardware.

Frequently Asked Questions
What industries does Kilandu build PCBA for?
Twelve application areas: medical and diagnostic devices, automotive electronics, industrial control and automation, inverters and energy storage, VFD and motor drives, consumer and digital products, connected devices and IoT, EV charging, test and measurement, audio equipment, LED lighting and AI hardware. All of them run through the same factory in Bao'an, Shenzhen.
Is Kilandu a turnkey PCBA supplier or an assembly-only service?
Turnkey. We source components from the BOM through authorised distribution channels, place and solder them on high-speed SMT and automatic DIP lines, then test and pack the finished assembly. You send the Gerber and BOM; we return tested boards.
What quality standards apply to these assemblies?
Every order runs through an ISO 9001 quality system with IPC-A-610 Class 2/3 acceptance criteria, and processes are RoHS and REACH compliant. Traceable inspection records are issued with each shipment.
What is the typical lead time?
For most applications, 2 to 5 weeks from the point the BOM and Gerber are confirmed and components are released, depending on material lead times, board complexity and whether tooling or test fixtures have to be built first.
Do you handle both prototype runs and volume production?
Yes. Buyers usually start with prototype or pilot quantities to validate the design and our process, then ramp to volume on the same lines, which keeps the process, materials and test method unchanged between the two stages.
Can you support both high-mix low-volume and high-volume orders?
Yes. The application areas above include customers running many low-volume variants and customers running single high-volume products. Because component sourcing, SMT, DIP, assembly and test all sit under one roof, we can schedule mixed demand without handing the job to a third party.
Can one supplier cover several product lines for us?
Yes. Customers with a mixed portfolio use Kilandu as a single source for fabrication, component sourcing, SMT, DIP, box build and test. That removes the coordination overhead of running several suppliers and keeps traceability in one production record.
How do I know which application page applies to my product?
Start from the product rather than the industry. A control board for a charging station is an EV charger board whether the end customer is an energy company or an equipment builder. If the classification is unclear, send the Gerber and BOM and we will tell you which process route and acceptance class we would quote.
Specialist and capability pages
Where the question is about a board capability rather than a sector - a fine-pitch package, a controlled-impedance stack, a coating - these pages cover it:
- High-density PCBA with BGA - 0.3 mm ball pitch, 01005 and fine-pitch QFN placement with 3D X-ray verification
- RF PCBA assembly - controlled impedance, low-loss laminate handling and RF shielding
- Conformal coating - acrylic, polyurethane and silicone coating with masking planned from the drawing
- Heavy copper PCB - thick-copper and metal-core constructions for high-current and thermal boards
- SMT assembly - the placement, reflow and inspection process itself, line by line
- DIP and through-hole assembly - wave and selective soldering for mixed-technology boards
Not sure which page applies to you?
Send the Gerber and BOM with a note on where the board is used and the environment it must survive. We will tell you which standard and process apply, and quote against it. Request a PCBA quote.
