What is the difference between full turnkey and partial turnkey PCB assembly?

In Full Turnkey PCB assembly, the vendor handles 100% of the process—from procuring every resistor, capacitor, and IC to final assembly, testing, and packaging. You only provide the Gerber design files and BOM. In Partial Turnkey (Consignment), you supply specialized, proprietary, or hard-to-find components yourself, while the manufacturer sources standard passives, fabricates the bare boards, and performs assembly and testing.

What are the key benefits of turnkey PCB assembly?

The three primary benefits of turnkey PCB assembly are: (1) Single Point of Contact: No need to coordinate between separate board fabricators, parts distributors, and assembly houses; (2) Faster Lead Times: Streamlined integrated workflows remove waiting gaps between different supply chain vendors; and (3) Lower Risk: The manufacturer verifies component compatibility, lifecycle status (NRND/EOL), and netlists early to catch design or sourcing issues before mass production.

PCB design is the engineering process of taking a circuit schematic and translating it into a physical board layout. It involves component placement, routing conductive copper traces across multiple layers, establishing continuous ground planes, observing design rule clearances (DRC), and generating RS-274X Gerber and drill files for manufacturing.

What is PCB fabrication?

PCB fabrication is the manufacturing process of producing bare, unpopulated circuit boards. It involves laminating FR-4 copper-clad substrate, photolithographic imaging, chemical copper etching, CNC drilling of via and component holes, copper plating, solder mask application, surface finishing (HASL or ENIG), and electrical flying-probe testing.

What is PCB assembly (PCBA)?

PCB assembly (PCBA) is the process of mounting and soldering active and passive electronic components (microcontrollers, resistors, capacitors, connectors) onto a bare fabricated PCB. It uses laser-cut solder paste stencils, automated high-speed surface-mount (SMT) pick-and-place machines, multi-zone reflow ovens, and manual through-hole (THT) soldering.

Do you provide PCB prototypes?

Yes. Tamizh Tech specializes in rapid prototype PCB fabrication and assembly, supporting quantities from 1 to 10 boards so engineers, startups, and college researchers can validate hardware before volume manufacturing.

Do you provide PCB assembly?

Yes. We offer turnkey PCB Assembly (PCBA) as well as consigned assembly where the customer provides components. Our assembly covers SMT packages down to 0402, QFNs, and robust through-hole terminal blocks.

Can you design a PCB from a schematic or breadboard circuit?

Yes. You can supply a circuit diagram, breadboard prototype photos, or simulation schematic. Our Coimbatore engineering team captures the schematic in professional EDA software, selects production-grade SMD parts, and designs the complete layout.

Can you work from existing Gerber files?

Yes. If your PCB layout is already complete, submit standard RS-274X Gerber files and Excellon drill files. We run automated and manual Design for Manufacturing (DFM) verification before initiating bare-board fabrication.

What PCB layers do you support?

We support 1-layer, 2-layer, and 4-layer standard FR-4 circuit boards for rapid prototyping and production, with controlled dielectric thickness and dedicated internal ground and power planes.

What PCB board dimensions can be manufactured?

We support board dimensions up to 400mm × 500mm, with the majority of robotics and IoT projects measuring between 25mm × 35mm (wearable/sensor nodes) and 100mm × 150mm (multi-motor robotics controllers). Custom milled polygon and circular outlines are supported via mechanical DXF files.

Do you source components?

Yes. In our turnkey PCBA service, Tamizh Tech sources authentic electronic components directly from authorized distributors (Mouser, Element14, DigiKey, LCSC) with complete BOM lifecycle verification.

Do you provide SMT assembly?

Yes. We provide automated Surface Mount Technology (SMT) assembly utilizing precision solder paste stencils, pick-and-place component placement, and profiled reflow soldering.

Do you provide THT assembly?

Yes. We provide manual and selective Through-Hole Technology (THT) soldering for heavy connectors, screw terminals, high-wattage power inductors, and relays requiring strong mechanical retention.

What files are required for a PCB quotation?

For layout design: circuit schematic (PDF, KiCad, or Altium), preliminary BOM, and physical board outline dimensions. For fabrication and assembly: standard RS-274X Gerber ZIP, Excellon drill file (.drl), Bill of Materials (.xlsx/.csv) with Manufacturer Part Numbers (MPNs), and Pick-and-Place centroid file (.csv).

How long does PCB prototyping take?

Typical turnaround time is 5 to 8 working days for bare board fabrication, and 8 to 12 working days for turnkey PCB assembly, depending on component availability and layer stackup. Fast-track options are evaluated per project.

What is the difference between 'PCB printing' and industrial PCB fabrication?

Colloquially, users often search for 'PCB printing' when referring to circuit board production. Unlike printing ink on paper, industrial PCB fabrication involves photolithographic chemical etching of copper-clad FR-4 laminates, CNC drilling, solder mask thermal curing, and automated SMT component soldering to withstand mechanical vibration and electrical thermal loads.

Service Overview

Complete Hardware Lifecycle: Schematic to Assembled Board

Turnkey PCB assembly is an end-to-end manufacturing service where a single provider manages every step of creating a printed circuit board, including design file review, component procurement, bare board fabrication, surface mount (SMT) and through-hole assembly, testing, and final delivery.

Tamizh Tech provides turnkey Printed Circuit Board (PCB) services tailored for robotics controllers, embedded systems, industrial telemetry, and IoT hardware developers in Coimbatore and across Tamil Nadu.

Instead of coordinating between separate design houses, board fabricators, and manual assembly technicians, our turnkey workflow covers component sourcing, bare board fabrication, SMT & THT assembly, and comprehensive inspection (AOI, X-ray, ICT). We support both Full Turnkey (where we handle 100% of procurement and production) and Partial Turnkey / Consignment (where you provide custom ICs and we source the rest).

A common search query among developers is 'PCB printing'. In engineering practice, PCB printing refers to industrial circuit board fabrication—a multi-step chemical etching, photolithographic imaging, CNC drilling, and solder mask curing process on FR-4 laminates rather than office paper printing. We deliver industry-grade, IPC-compliant fabricated and assembled circuit boards built for harsh environments.

We also assist engineering teams in optimizing physical board dimensions (length × width), component density, and layer stackups. Whether you are packaging a micro sensor node (25mm × 35mm), an ESP32/STM32 controller (50mm × 70mm), or a high-current motor driver (80mm × 100mm), our engineers ensure proper mounting hole keep-outs, connector clearances, and thermal dissipation paths before releasing Gerber files.
