Turnkey PCBA Manufacturing & SMT Assembly in China
Kilandu (Shenzhen Jintianlei Innovation Technology Co., Ltd.) is a turnkey PCBA and EMS manufacturer based in Bao'an District, Shenzhen, China. We take projects from Gerber and BOM to tested, ready-to-use boards: PCB fabrication, authorised component sourcing, SMT and through-hole (DIP) assembly, functional testing, conformal coating and final box build.
Our team of 150+ people, including more than 20 engineers and quality specialists, runs four fully automatic Yamaha YS24 + YS12 SMT lines and three automatic DIP lines with lead-free wave soldering, giving a monthly placement capacity of 150 million components. Production follows IPC-A-610 Class 2/3 acceptance under an ISO 9001 quality system, with RoHS/REACH-compliant processes and traceable inspection records for every batch.
We support rapid prototyping, small-batch production and volume manufacturing under one quality system, and supply customers in industrial control, EV charging and energy storage, automotive electronics, medical and diagnostic devices, connected devices, instrumentation and consumer electronics across Europe, Russia and the Americas.
Inside the factory. Fabrication, assembly, test and box build run under one roof, so a change agreed at design review carries through to the shipped unit without a handover between vendors.
How we control quality. Solderability and tin-thickness checks, pull-strength testing on critical joints, reflow profiling for every product, and full functional testing on customer-specific fixtures — see the quality assurance workflow.
What we build. EV charging and energy storage, industrial control, vehicle vision, wearables and medical devices — assembled, tested and box-built under one roof in Bao'an, Shenzhen.

Application
Each application area has its own assembly requirements. What changes from a medical instrument to a motor drive is the process, the acceptance class and the design rules that matter, and the pages below set out what is different about each one.
The Cyber Resilience Act reporting duty has been live since 11 September 2026 and it covers products already in the field. A manufacturer has 24 hours to issue an early warning once it becomes aware of an actively exploited vulnerability.
For industrial board buyers, the bottleneck is not legal interpretation. It is whether the build records needed to answer three specific questions exist and can be retrieved.
TrendForce contract price data updated on 30 October 2026 shows DDR4 modules and components moving up for another month while the DDR5 8GB SO-DIMM held flat. The split reflects wafer capacity leaving mature memory for AI server products rather than a shortage of DDR4 demand.
For buyers of industrial control boards, the exposure sits in the BOM: allocation cuts, end-of-life notices and repricing on parts that were qualified years ago.
Regulation (EU) 2023/1230 applies from 20 January 2027. The harmonised standards list that supports the outgoing Machinery Directive is repealed on the same day, and no replacement list had been published under the new Regulation at the start of November 2026.
For buyers of industrial control boards, the question is whether the assembly supplier can document revision, substitution and test records that the machine builder needs for its technical file.
