Why choose us?
Why choose Kilandu? Because one factory in Bao'an, Shenzhen covers the whole path from Gerber and BOM to tested boards: 4 automatic Yamaha SMT lines and 3 automatic DIP lines, 150 million component placements a month, ISO 9001 and IPC-A-610 Class 2/3 quality, and turnkey component sourcing for customers in Europe, Russia and the Americas. These are the eight reasons they stay with us.
Advanced production equipment
Kilandu runs 4 fully automatic Yamaha YS24 + YS12 SMT lines and 3 automatic plug-in lines with lead-free wave soldering at our Shenzhen plant, with a monthly placement capacity of 150 million components. Automated optical inspection (AOI) and functional testing sit in the same flow, so high-mix and high-volume orders share one stable process.
Rich industry experience
Kilandu's team of 150+ people includes more than 20 engineers and quality specialists who have delivered turnkey PCBA for industrial control, EV charging and energy storage, automotive infotainment, medical devices, IoT, instrumentation and smart home projects across Europe, Russia and the Americas.
Strict quality control system
Every Kilandu order runs through an ISO 9001 quality system with IPC-A-610 Class 2/3 acceptance criteria. Incoming components are checked against the BOM and approved-vendor list, and each batch ships with traceable inspection records covering solder paste, reflow profile, AOI and final functional test.
Efficient testing process
Assemblies are validated with automated optical inspection (AOI) and functional testing on customer-specific test fixtures before packing, and failed units go back through documented rework and retest. RoHS/REACH-compliant processes and test records are issued with every shipment, so incoming inspection at your end stays fast.
Optimized cost control
Turnkey sourcing, 4 SMT lines and 3 DIP lines under one roof remove the margin stacking of a multi-vendor supply chain. Kilandu shares the BOM cost breakdown, flags long-lead and single-source parts early, and proposes pin-to-pin alternatives before production starts.
Efficient supply chain management
Kilandu buys from authorised and franchised distributors, so components are traceable and counterfeit risk is controlled. Long-term agreements cover passives, connectors, MCUs and power devices, and our Shenzhen location gives fast access to China's component market and short lead times from BOM release to first article.
Social responsibility and sustainable development
Kilandu builds with lead-free wave soldering and RoHS/REACH-compliant materials and operates under Shenzhen's environmental, health and safety regulations. On request we supply material declarations, RoHS/REACH statements and packaging data, so European customers can complete their own compliance and sustainability reporting.
Perfect after-sales service system
Kilandu (Shenzhen Jintianlei Innovation Technology Co., Ltd.) provides 7x24 online support and long-term technical follow-up after shipment. Questions are answered by the engineering team that built the boards, and traceable QC records for each batch let us trace any issue back to the exact process step.
Application
Kilandu (Shenzhen Jintianlei Innovation Technology Co., Ltd.) supplies turnkey PCBA to 3,000+ OEM customers across eight application areas: medical devices, automotive infotainment, smart home, energy storage, VFD, industrial equipment, IoT and AI hardware.
