Turnkey PCBA Manufacturing & SMT Assembly in China

About Kilandu

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 infotainment, medical devices, IoT, instrumentation and smart home across Europe, Russia and the Americas.

How components and a bare board become a tested assembly: paste printing, placement, reflow, through-hole and mixed-technology work, and the control at each stage.

PCBA assembly

How the electrical design becomes a physical board: layer count, base material, copper weight, trace and gap, surface finish — and what is reviewed first.

PCB manufacturing

What happens to a bare board before assembly: drilling, plating, etching, solder mask, surface finish and profiling, then electrical test.

PCB processing

Kilandu PCBA and SMT assembly factory in Shenzhen, China

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.

Why choose us?

Why choose Kilandu? Because one factory in Bao'an, Shenzhen covers the whole path from Gerber and BOM to tested boards — fabrication, sourcing, assembly, test and box build under one roof, with the same team accountable from first quote to repeat order. These are the eight reasons they stay with us.

Advanced production equipment

How the SMT and DIP equipment set is matched to the product: placement accuracy, fine-pitch printing and reflow profiling, and what each machine is for.

Rich industry experience

What a broad project history changes in practice: the failure modes already seen, the questions asked earlier, and why sector range shortens the learning curve.

Strict quality control system

The control points where quality is actually decided: incoming material checks, in-process inspection, the acceptance class and the batch records.

Efficient testing process

The test stages a board passes through, how fixtures and specification are agreed, and the discipline applied to rework before a board is retested.

Optimized cost control

Where PCBA cost actually sits, which levers genuinely move it, and what we will not do to reach a lower number — an open breakdown rather than a negotiated rate.

Efficient supply chain management

How components are sourced and held: authorised channels, traceability, agreements and inventory, and the plan when a part goes short or obsolete.

Social responsibility and sustainable development

Where a manufacturer's obligations start and the brand owner's continue: WEEE, packaging and battery duties, material declarations, and people and safety practice.

Perfect after-sales service system

What happens after a shipment leaves: how a problem is reported, who answers, how a replacement batch is scheduled, and why the batch records make it possible.

Application

Eight application areas, each with 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.

Frequently Asked Questions

What is turnkey PCBA manufacturing?+

Turnkey PCBA means a single supplier handles everything for you: PCB fabrication, SMT and through-hole assembly, component sourcing, functional testing, conformal coating and final box build. You send the Gerber files and BOM, and we deliver tested, ready-to-use boards.

Which industries do you serve?+

We mainly serve industrial electronics, industrial automation, control systems, EV charging, medical devices, automotive infotainment, IoT, instrumentation and consumer electronics manufacturers that need reliable OEM/ODM PCBA.

Do you support both prototyping and mass production?+

Yes. We support low-volume prototyping, NPI trials and high-volume mass production under one quality system, so your design can scale from sample to shipment without changing suppliers.

What certifications does your factory hold?+

Kilandu holds IATF 16949:2016 (IATF No. 0596984, IATF USI L3A259), ISO 9001:2015 (cert. CN27125Q0392R0S), ISO 13485:2016 (cert. 35825MDQMS0021R0S) and ISO 14001:2015 (cert. CN27125E0142R0S) management-system certifications, plus UL listing (File No. E352816). Production follows IPC-A-610 Class 2/3 acceptance criteria with RoHS and REACH compliant processes, and every batch ships with traceable inspection records and test reports.

Can you source components globally?+

Yes. We source components from authorised global channels, support full BOM sourcing, and can advise on equivalent or alternative parts when originals are long-lead or allocated, with your approval.

What is your typical PCBA lead time?+

Prototypes usually ship within 1 to 2 weeks, while mass production lead time depends on BOM and order quantity and is confirmed after a formal quotation. Urgent orders can be prioritised on request.
