PCB design · Assembly · Manufacturing — Pune, India
Electronics. Engineered.
PCB design, electronics assembly and product manufacturing under one roof. From your first prototype to production-ready hardware.
- ESP32-S3 module — Wi-Fi + Bluetooth LE, 8 MB flash, 8 MB PSRAM
- USB-C — native USB for flashing and debugging
01 / Capabilities
One workshop, from schematic to shipped board.
Design, fabrication, assembly and firmware happen in the same place, by the same team. That keeps decisions close to the people who build the hardware.
01 — PCB DESIGN
PCB Design
Schematic capture, component selection and 2 to 6-layer layout, checked against how the board will actually be fabricated and assembled. You get Gerbers, BOM and pick-and-place files ready for production.
PCB design services 02 — PCB ASSEMBLYPCB Assembly
SMT and through-hole assembly on our own pick-and-place line: stencil, placement, reflow and inspection. Use parts we source or supply your own kit.
PCB assembly services 03 — MANUFACTURINGElectronics Manufacturing
Bare PCBs, assembly, 3D-printed and CNC-machined enclosure parts, laser marking and packing — one order and one point of contact.
Manufacturing services 04 — PRODUCT DEVELOPMENTProduct Development
From an idea to a working device: architecture, PCB, firmware and enclosure, iterated until it is ready to build in quantity.
Product development 05 — PROTOTYPINGPrototyping
Prototype boards and assemblies to prove a design before committing to a batch, with fabrication typically in 3 to 5 days.
Electronics prototyping 06 — EMBEDDEDEmbedded Electronics
ESP32 and ESP32-S3 based hardware with firmware written, flashed and tested in-house — the platform we build our own products on.
Firmware & embedded02 / Shop
Boards and parts, ready to ship from Pune.
The ESP32 boards we build our own products on, and the components we stock for production. Prices include 18% GST and are confirmed by our server at checkout.

03 / How we build
The production workflow, end to end.
Each stage can be ordered on its own. Most projects use several, and none of them needs to leave the building.
PCB design
Schematic, layout and a design-for-manufacture review before any files are released.
Component sourcing
We source parts against your BOM, or you supply a kit. Common passives, LEDs and regulators are held in stock.
PCB fabrication
2, 4 and 6-layer FR4 boards with ENIG or HASL finish. Files are reviewed before production.
SMT assembly
Solder-paste stencil, placement on NeoDen N9 and YY1 pick-and-place machines, then reflow.
Through-hole assembly
Connectors, headers and other through-hole parts are hand soldered after SMT.
Firmware integration
Firmware written and flashed in-house for ESP32 and ESP32-S3 based designs.
Testing & inspection
Boards are inspected after reflow. Functional testing is scoped with you in the quote.
Prototype to small batch
The same line builds a single prototype and the batches that follow it.
04 / Why CktHub
Fewer hand-offs between design and production.
Most hardware delays happen between vendors: a layout one shop can't assemble, a BOM another can't source. We keep those steps in one place.
One point of contact
Design, fabrication, assembly and enclosure questions go to the same engineers, on one WhatsApp thread.
Less coordination
Layouts are checked against our own assembly process, so files don't bounce between a design house and a factory.
Prototype to production
Your first prototype and your next batch are built on the same line, with the same files.
Engineering-led
We build and ship our own ESP32-based products, so customer boards go through the same process and checks as ours.
Custom hardware
When an off-the-shelf module doesn't fit, we design the board around your requirement instead.
Published pricing
PCB, assembly, 3D print, laser and CNC rates are on our instant quote page, not hidden behind a sales call.
05 / Questions
What customers ask before they send files.
What is PCB assembly?
PCB assembly (PCBA) is mounting and soldering components onto a bare printed circuit board. Surface-mount parts are placed onto solder paste by a pick-and-place machine and soldered in a reflow oven; through-hole parts are inserted and soldered afterwards. The result is a working circuit board. More on PCB assembly
Does CktHub provide PCB design services?
Yes. We design PCBs in-house: schematic capture, component selection, 2 to 6-layer layout, and the Gerbers, BOM and pick-and-place files needed to build the board. PCB design services
Can CktHub manufacture prototype PCBs?
Yes. We supply 2, 4 and 6-layer FR4 boards with ENIG or HASL finish, typically in 3 to 5 days, and can assemble them as well. The instant quote page gives an estimate before you send files.
Does CktHub support small-batch production?
Yes. Boards are assembled on our own NeoDen pick-and-place line in Pune, so the process that builds your prototype also builds the next batch.
What information is needed for a PCB assembly quotation?
Board quantity; whether parts are on one or both sides; the number of SMT parts, fine-pitch and BGA parts and through-hole pins per board; the number of unique BOM lines; whether you need a stencil; and who supplies the components. For production, send Gerbers with paste layers, a BOM (designator, value, footprint, MPN, quantity) and a pick-and-place / centroid file.
Can customers provide their own components?
Yes. You can supply a kit of components, or we source them for you; sourced parts are quoted after we check your BOM.
What is the process for developing a custom electronic product?
We start from your requirements, define the electronics architecture, design the PCB, build and test a prototype, write and flash the firmware, iterate, and then move to small-batch production — with fabrication, assembly and enclosure parts made in the same workshop. Product development
