Advanced PCB Technologies and Future Developments

• Register action Layer (RDL) and Flip Chip Ball Grid Array (FCBGA) technology are at the forefront of PCB advancements.
• Advantages include low cost, high density, and up to 20 layers for flip-chip ball grid array package carriers.
• FCBGA technology integrates the Modified Semi-Additive Process (mSAP) for precise control over line width.
• Future developments aim to achieve line widths in the 2 to 3 microns range.
• Selection of PCB materials is crucial, considering thermal, mechanical, and physical properties.
• Dielectric materials must carefully align positive and negative signals to avoid delays.
• Process considerations include designing via hole shapes and ensuring smooth copper surface treatment.
• Surface treatment addresses the skin effect, improving conductivity and signal quality.
• Minimizing thermal resistance is essential through various techniques.
• Emerging technologies pose challenges in PCB production, emphasizing the need for adaptation and talent recruitment.
