MARKET CHALLENGES
Stringent Cost Structures and Manufacturing Complexity
The adoption of SLP technology faces significant hurdles due to the specialized fabrication requirements and high capital expenditure. Unlike conventional copper-clad laminates, Substrate-like PCBs require process steps borrowed from semiconductor manufacturing, such as double-sided patterning and thin dielectric layers. This complexity results in higher per-unit costs, which can be a deterrent for cost-sensitive markets, despite the performance gains offered by the technology.
Other Challenges
Yield Rates and Defect Sensitivity
The manufacturing yield rates for Substrate-like PCBs are currently lower than those for traditional organic boards. The extreme miniaturization of features,sometimes as small as 30 microns,makes the production process extremely sensitive to defect formation, such as particles and alignment errors. This variability impacts the bottom line and necessitates rigorous quality control measures, slowing down the overall mass production scalability.
Material Limitations
The availability of advanced stacking dielectric films and high-performance ABF (Ajinomoto Build-up Film) materials is often a bottleneck, as these are patented and produced predominantly by a few key suppliers.
