LPKF NEXAR Ablate 5000

Redefining RDL Ablation for Glass Core Substrates

The LPKF NEXAR Ablate 5000 brings a fundamentally new approach to RDL removal on glass. Its highly selective, ultra-short pulse Tensor Ablation process cleanly removes redistribution layers and dielectrics without damaging the glass core preventing SeWaRe-induced splitting and preserving full mechanical integrity at panel level. Material-optimized optics and real-time process control make it the complete solution for glass-safe singulation and edge preparation in advanced packaging.

LPKF NEXAR Ablate 5000 – Precision RDL Ablation Without Yield Loss

The LPKF NEXAR Ablate 5000 is the dedicated production system for glass core substrate singulation and edge preparation in advanced packaging. It uses Tensor Ablation, a proprietary ultra-short pulse laser process to selectively remove copper RDL and build-up dielectrics such as ABF while leaving the glass substrate completely intact. Where conventional ablation methods introduce microdamage, thermal stress, and hidden SeWaRe defects that split glass internally, NEXAR Ablate 5000 stops SeWaRe at its source. The result is clean, defect-free edges, robust substrates, and significantly higher yield across panel-level fan-out, glass core packages, and high-density interposers.

 
Process advantages through Tensor Ablation


Damage-free integrity: No microcracks, fracture planes, or SeWaRe; full strength retained.

Clean edge quality: Minimal HAZ, no redeposition; micron-level precision.

Low thermal stress: No heat diffusion, eliminating CTE stress and thermal damage.

High selectivity: Precise removal across metals, polymers, and glass.

 

 
Simple operation and high automation


Automated handling: Fully automated loading, alignment, processing, and cassette return.

Monitoring & inspection: Real-time control with inline defect detection.

Stable performance: High uptime, predictive maintenance, and recipe-based scaling to HVM.

Scalable throughput: High-speed scanning with throughput scaling by panel size and ablation area.

NEXAR Ablate 5000 – Redefining RDL Ablation on Glass

The most efficient solution for damage‑free glass core singulation

The LPKF NEXAR Ablate 5000 brings Tensor Ablation into production, delivering selective RDL and dielectric removal with zero substrate microdamage. By preventing the SeWaRe effect at its source, the system enables clean, defect‑free edges and preserves the full mechanical integrity of glass cores throughout downstream processing. Whether used for glass core substrates, panel‑level fan‑out, or high‑density glass interposers, NEXAR Ablate 5000 combines ultra‑short pulse laser technology, high material selectivity, and real‑time process monitoring to provide reliable, high‑yield RDL ablation for advanced packaging.
