IoT Electronics Manufacturing Capabilities
Connected products tend to be small, dense and full of radios, sensors and compact electronic components, often moving from prototypes and pilot builds to larger production runs. Our IoT electronics manufacturing capabilities support this journey from early-stage builds through production.
PCB Sourcing for Compact Designs
We source bare boards to your stack-up and layer count through qualified fabrication partners, including the tight, multi-layer boards required for compact IoT devices and custom IoT PCB assembly.
Component & Module Sourcing
Alongside standard components we manage procurement of the wireless modules, sensors and connectors that IoT BOMs depend on, and track availability against your build plan.
SMT Assembly for Dense Boards
Automated SMT lines place fine-pitch parts, modules and passives on compact boards, with through-hole assembly available where connectors or power components require it. This supports IoT PCB assembly for dense, connected devices.
Prototype & Pilot Builds
Prototype and pilot builds let product teams validate hardware, firmware and enclosure fit together before committing to a production run. This provides IoT hardware prototyping services for connected products at the early stages of development.
Low-Volume Production
Low-volume production suits pilot deployments, field trials and first customer shipments, without the minimum order quantities that make early IoT builds difficult to place.
AOI & X-Ray Inspection
Automated optical inspection checks placement and joints across the board, and X-ray inspection reaches the connections under modules and bottom-terminated packages.
Functional Testing
Functional testing is built to your specification, so units are verified against the behaviour you define before they leave the line. Test requirements can be incorporated into the manufacturing process for connected devices.
Conformal Coating
Conformal coating is available where IoT devices are deployed outdoors, in utility cabinets or in other environments where moisture and dust are a risk.
Scaling to Volume
When a pilot turns into a rollout, the same documented process carries the product into larger production runs, supporting the transition from prototype and pilot builds to IoT device manufacturing at scale.
Why IoT Product Teams Choose Karkhana
IoT hardware teams need flexibility during prototyping and pilot production, followed by consistent processes as volumes grow. Karkhana provides IoT device manufacturing from early builds through production, with the same manufacturing partner supporting each stage.

Hardware Startup to Scale
We build prototypes and pilot batches for early-stage teams, then scale the same documented process as the product moves into production. Our IoT hardware prototyping services help teams validate manufacturability before larger production runs.
Wireless Module Assembly
Careful handling and placement of Bluetooth, Wi-Fi, cellular, GPS and other RF modules during SMT assembly.
Sourcing Through Shortages
Qualified supplier networks and active BOM management help keep builds moving when a module or sensor goes long on lead time, supporting continuity from prototype builds through production.
Small Batches Welcome
Pilot runs and low-volume batches are supported alongside larger production requirements, giving IoT product teams a practical path from early builds to wider deployment.
DFM for Miniaturised Boards
Our engineers review dense, miniaturised layouts for manufacturability before build, helping identify potential assembly and yield issues early in the IoT device manufacturing process.
Build Traceability
Documented processes and batch records provide traceability across IoT electronics manufacturing, so a field issue can be traced back to the specific build it came from.
Enclosure & Final Assembly
Wire harnesses, mechanical assembly and enclosure integration support IoT device assembly services, so connected devices can ship as finished products rather than loose boards.
One Point of Contact
A dedicated team coordinates sourcing, production, quality and delivery through one workflow, giving IoT product teams a single manufacturing partner from prototype through production.
Looking for an IoT Manufacturing Partner in India?
Karkhana builds connected products with integrated sourcing, SMT assembly, testing and final device assembly.
IoT Contract Manufacturing Services
Karkhana works as a contract manufacturer for IoT product companies, hardware startups and OEMs developing connected products. We coordinate PCB procurement, component and module sourcing, SMT assembly, inspection, testing and final assembly through one manufacturing workflow. This provides turnkey electronics manufacturing for IoT devices, from prototype and pilot builds through production.
For a small hardware team, this brings sourcing, PCB assembly, testing and device integration together with one manufacturing partner, reducing the need to coordinate multiple vendors while taking a connected product from development to production.
Connected Products We Manufacture
Connectivity now sits inside products across utilities, security, health, mobility and industrial monitoring. Karkhana supports IoT device manufacturing across these applications, from connected electronics and sensing boards to complete devices and assemblies. These are the categories we build most often.
Smart Energy Meters
Connected meters that monitor and transmit energy consumption data.
Smart Locking Solutions
Electronic locking systems with connected access and control features.
Wearable Devices
Compact connected devices that capture, process and transmit user or activity data.
Telematics Units
Connected electronics that collect and transmit vehicle or asset data.
Process Control Systems
Electronic systems that monitor and control industrial processes and equipment.
Home Care Solutions
Connected electronic devices designed for monitoring, assistance and everyday home care.
From IoT Boards to Finished Connected Products
A connected product is rarely just a PCBA. Karkhana provides IoT device assembly services beyond PCB assembly, including wire harness manufacturing, mechanical assembly and enclosure integration, so connected electronics can move from assembled boards to finished products.
Our integrated manufacturing capabilities cover PCB assembly, box build assembly, wire harness manufacturing, mechanical assembly, functional testing, component sourcing and system integration. This gives IoT product companies a streamlined path from individual boards to complete, tested devices.
With these capabilities managed through one manufacturing partner, Karkhana supports turnkey electronics manufacturing for IoT devices, helping simplify vendor coordination and move products from prototype and pilot builds into production.
