3
PCB Design Architectures

Explore microvias, stacked vias, and via-in-pad technologies in UHDI PCB design.

4
Practical Experience

Take a facility tour to identify UHDI-specific boards and manufacturing techniques, and study real-world case studies of UHDI designs.

MODULE 2: UHDI Materials and Advanced Stack-Up Design
Materials for UHDI Boards

- High-frequency materials: Rogers, Taconic, and Isola - Ultra-thin copper foils and flexible laminates

Stack-up Design Techniques

- Use of embedded components and integrated passives - Multilayer stack-ups with controlled impedance - Managing signal integrity challenges in UHDI

Thermal Management and Design Tools

- Use of copper pillars for heat dissipation - Graphene and other advanced thermal materials - CAD software with UHDI-specific templates (Altium, Mentor Graphics)

MODULE 3: UHDI Manufacturing Technologies
1
Microvia Formation

Advanced laser drilling (UV and COâ‚‚ hybrid systems), stacked and staggered via configurations, and via-in-pad techniques for increased density.

2
Copper Via Fill Plating

Ultra-thin copper deposition and plating for 1-mil traces and sub-mil spaces.

3
Solder Mask Application

LDI (Laser Direct Imaging) techniques for fine lines and tight tolerances, and techniques to avoid solder mask creep.

4
Advanced Packaging Techniques

Embedded components for system-on-board (SoB) designs, UHDI integration with chip-scale packaging (CSP), and 3D printed circuits and additive manufacturing.

MODULE 4: Quality Control and Reliability Testing for UHDI Boards
Electrical Testing for UHDI Boards

Flying probe testing with ultra-fine pitch capabilities and Time Domain Reflectometry (TDR) for signal integrity validation.

Optical and X-Ray Inspection

AOI setup for 1-mil line and space resolution and X-ray inspection for buried vias and stacked microvias.

Environmental and Thermal Stress Testing

Thermal shock and aging tests, and high-frequency performance tests. IPC Standards for UHDI: IPC-6012 and IPC-2226 standards.

MODULE 5: Process Optimization and Manufacturing Scalability
1
Lean and Six Sigma for UHDI Production

Process streamlining for high yields in UHDI manufacturing and root cause analysis and corrective actions (RCA/CA).

2
OEE and TPM Implementation

Optimizing machine utilization for fine-pitch components and proactive maintenance for laser drilling and plating machines.

3
Yield Optimization

Mitigating common UHDI defects (via voids, misaligned traces) and use of AI and machine learning for predictive maintenance.

4
Blockchain-based Supply Chain Traceability

Tracking raw materials and components with blockchain and counterfeit component mitigation.

MODULE 6: Capstone Project and Certification
1
Project Requirements

Design a functional UHDI PCB with embedded components and microvias, manufacture the board using advanced processes, perform signal integrity tests and AOI inspections, and document design challenges, process improvements, and defect mitigation.

2
