Turnkey PCB Services: Design, Fabrication & Assembly (PCBA)
End-to-end circuit board engineering — from schematic capture and multi-layer layout to rapid prototype fabrication, component assembly (PCBA), and hardware bench testing.
Complete Hardware Lifecycle: Schematic to Assembled Board
Tamizh Tech provides turnkey Printed Circuit Board (PCB) services tailored for robotics controllers, embedded systems, industrial telemetry, and IoT hardware developers.
Instead of coordinating between separate design houses, board fabricators, and manual assembly technicians, our turnkey workflow covers schematic capture, multi-layer routing, Design for Manufacturing (DFM) verification, bare board fabrication, SMT/THT component assembly, and hardware power rail testing.
Turnkey PCBA Workflow
Single-source coordination from circuit schematic to assembled, tested boards.
Prototype to Small-Batch Runs
Supporting quick-turn 1-10 prototype boards to 100+ unit pilot production.
Hardware Bring-Up & Testing
Visual inspection, power rail continuity verification, and basic firmware flashing.
What We Provide
Practical, in-house technical capabilities backed by proven hardware methodologies and quality control.
Schematic Capture & Component Selection
Designing clean circuit schematics, selecting reliable in-production components, and generating verified Bills of Materials (BOM).
Multi-Layer PCB Layout & Routing
1-layer, 2-layer, and 4-layer PCB routing with proper ground planes, trace width calculation for high current, and noise isolation.
Design Rule Checking (DRC & DFM)
Validating minimum trace clearance, drill hole aspect ratios, annular rings, and solder mask expansion prior to fabrication.
Bare Board Fabrication
High-quality FR-4 glass epoxy fabrication with solder mask, crisp silkscreen legend, and Lead-Free HASL or ENIG gold finishes.
Surface Mount & Through-Hole Assembly (PCBA)
SMT solder paste stencil printing, reflow soldering, hand placement of fine-pitch ICs, and durable through-hole terminal soldering.
Bench Inspection & Hardware Bring-Up
Microscopic solder joint inspection, short-circuit continuity checks, DC power rail verification, and initial firmware loading.
PCB Specifications & Capabilities
Verified manufacturing specifications supported for prototype and small-batch orders:
Substrate & Layers
Standard FR-4 glass epoxy substrate available in 1-layer, 2-layer, and 4-layer configurations with controlled dielectric thickness.
Surface Finishes
Lead-Free HASL (Hot Air Solder Leveling) for standard boards, and ENIG (Electroless Nickel Immersion Gold) for fine-pitch surface-mount ICs.
Solder Mask & Legend
High-contrast solder masks (Standard Green, Matte Black, Blue, Red) with legible component silkscreen reference designators.

Bare Board Fabrication
Precision substrate etching, via plating, solder masking, surface finishing, and flying probe testing.
Component Assembly (PCBA)
SMT stencil printing, component placement, reflow soldering, and manual through-hole connector soldering.
Hardware Bring-Up & Dispatch
Microscopic joint inspection, DC power rail validation, safe anti-static packaging, and tracked shipping.
