From initial concept to finished product, creating a PCB involves multiple stages of design, verification, and manufacturing. At AI Connects Engineering, we handle the complete workflow in-house.
Stage 1: Schematic Design
Every project begins with schematic capture—translating requirements into an electronic circuit:
- Component selection based on availability, cost, and performance
- Power supply architecture and regulation
- Signal routing and interface design
- Protection circuits and safety features
Design Review
Before moving to layout, we conduct thorough design review covering functionality, component availability, and manufacturability.
Stage 2: PCB Layout
The layout stage transforms the schematic into a physical board design:
- Layer Stack-up: Determining number of layers and copper weights
- Component Placement: Optimising for signal integrity and thermal management
- Routing: Connecting components while maintaining impedance requirements
- DFM: Ensuring design is manufacturable with standard processes
Stage 3: Fabrication
We work with trusted fabrication partners for bare boards:
- Standard FR-4 for general applications
- High-Tg materials for elevated temperatures
- Rogers and RF substrates for high-frequency designs
- Flexible and rigid-flex constructions
Stage 4: Assembly
Our assembly services handle boards from simple to complex:
- SMT assembly with fine-pitch and BGA capability
- Through-hole assembly and hand soldering
- Conformal coating for environmental protection
- Box build and system integration
Stage 5: Testing
Every assembled board undergoes rigorous testing:
- Visual inspection and AOI
- In-circuit testing (ICT)
- Functional testing
- Burn-in testing for reliability-critical applications
