Confirm ABF Substrate Manufacturing Feasibility
JETFGO provides engineering and manufacturing support for ABF IC package substrate projects requiring ultra-fine routing, high-density build-up structures and advanced semiconductor interconnection. ABF, or Ajinomoto Build-up Film, is a build-up dielectric material widely used in advanced semiconductor package substrates. It enables laser microvia formation and fine copper circuit fabrication for high-density interconnections between semiconductor packages and system-level printed circuit boards. Our listed ABF substrate capability includes any-layer structures up to 10 layers, laser microvias from 50 μm, fine line / space in the 10–30 μm class and SAP / mSAP processing, subject to material, stack-up, package size and engineering review. ABF package substrate technology is relevant to high-performance processors, AI accelerators, semiconductor systems, networking devices and other advanced packages requiring high I/O density and compact interconnect structures. Each ABF IC substrate project is reviewed individually by our engineering team to confirm materials, build-up structure, feature size, process capability, inspection requirements and production feasibility before quotation.
