PCB Design & Manufacturing Services | PCB Prototyping & Assembly

Phase 01

Schematic Design & System Architecture

Our schematic development is driven by a methodical, constraint-aware engineering process, ensuring that the design is electrically correct, scalable, and layout-ready from the outset.

Project Setup

Define project structure, libraries, naming conventions, and version control baseline. This ensures traceability and consistency across the design lifecycle.

Symbol Definition & Library Management

Use verified symbols from controlled libraries or create new ones with strict pin mapping validation. Library integrity is maintained to avoid downstream mismatches.

Component Association & Annotation

Assign footprints, annotate designators, and validate symbol-to-footprint linkage. This step ensures seamless transition into PCB layout without ambiguity.

Schematic Wiring

Implement circuit connectivity with clear hierarchy, net labeling, and organized signal flow for maximum readability.

Net Definition & Connectivity Structuring

Define global and local nets with proper naming conventions. Critical nets (power, clocks, high-speed lines) are explicitly controlled for layout intent.

Electrical Rules Check (ERC)

Run systematic ERC to detect connectivity issues, missing drivers, pin conflicts, and logical inconsistencies. All violations are resolved or formally justified.

Design Documentation & Review

Embed engineering notes, assumptions, and constraints directly into the schematic. Internal review checkpoints ensure design completeness before layout handoff.

Outcome

A fully validated, layout-ready schematic with aligned libraries, clean connectivity, and zero ambiguity for PCB implementation.

Phase 02

PCB Design & Layout Engineering

We execute PCB design with a focus on signal integrity, power integrity, EMI/EMC performance, and manufacturability. Every board is engineered to perform reliably in real-world conditions—not just in CAD.

STEP 01

Layout Setup

Import schematic, define board stack-up, layer configuration, and design rules aligned with fabrication capabilities and electrical requirements.

STEP 02

Board Outline & Constraints

Establish mechanical outline, mounting constraints, keep-outs, and interface locations. Electrical constraints such as impedance, clearance, and creepage are defined upfront.

STEP 03

Footprint Validation & Placement

Verify footprints against datasheets and manufacturing tolerances. Placement strategy is planned based on functional blocks, signal flow, and thermal behaviour.

STEP 04

Routing Execution

Controlled impedance for high-speed lines, short return paths and proper grounding, separation of noisy and sensitive domains, and current-carrying trace sizing based on load.

STEP 05

Silkscreen & Assembly Layer

Add clear component markings, polarity indicators, and assembly references to support manufacturing and debugging.

STEP 06

Design Rules Check (DRC)

Run comprehensive DRC covering spacing, width, via constraints, and fabrication limits. All violations are resolved with manufacturability in mind.

STEP 07

Manufacturing Data Generation

Export Gerber/ODB++, drill files, pick-and-place, and assembly drawings. Outputs are validated for fabrication and assembly readiness.

Phase 03

Prototyping, Testing & Validation

This phase ensures that the design transitions from theory to verified, field-ready hardware through structured validation and iterative refinement.

01

Prototype Build Setup

Coordinate with fabrication and assembly vendors. Validate fabrication outputs, BOM alignment, and component availability.

02

Assembly & Quality Verification

Ensure assembly quality through visual inspection, polarity checks, solder integrity, and critical component verification.

03

Bring-Up Procedure

Execute controlled power-up sequence including power rail validation, current consumption checks, interface initialization, and clock/signal verification.

Power rail validation

Current consumption checks

Interface initialization

Clock & signal verification

04

Functional Testing

Validate system behaviour against design intent across peripheral functionality, signal integrity, thermal performance, and load testing.

Peripheral functionality

Signal integrity observations

Thermal performance

Load testing

05

Iteration & Debug Cycle

Identify design gaps, implement corrective actions, and refine the design. Changes are tracked and validated systematically.

06

Design Validation Review

Perform final validation against requirements, including edge cases and operating limits.

07

Pre-Production Readiness

Freeze design for manufacturing with validated documentation, ensuring smooth transition to volume production.
