At Avecas, our Assembly & Advanced Packaging services cover the full spectrum—from traditional wire bond through heterogeneous chiplet integration. We support consumer, automotive, HPC, and IoT devices from NPI through high-volume production.
End-to-End Package Support
From package selection and substrate design to final assembly and test, Avecas manages the full flow—reducing handoff risk between design and manufacturing.
Advanced Technology Readiness
We support 2.5D/3D-IC, FOWLP, and chiplet integration alongside established wire bond and flip-chip flows.
Automotive & High-Reliability Focus
AEC-Q100/Q101 compliant package qualification, JEDEC reliability testing, and PPAP documentation for automotive customers.
Feel free to email us on below email address, we will be happy to answer your queries.
AEC-Q100/Q101-capable qualification, JEDEC reliability testing, and full PPAP traceability for high-reliability programmes.
Our packaging capabilities span wire bond, flip-chip, fan-out, 2.5D/3D, and SiP—all under one roof. We coordinate with fab, substrate, and OSAT partners to deliver a seamless package solution.
Turnkey wire bond assembly for QFP, BGA, LGA, and CSP packages with fine-pitch capability, multi-tier stacked-die, and MCM configurations.
Fan-Out Wafer-Level Packaging (FOWLP/eWLB) for thin, compact, high-I/O devices including mobile SoCs, RF modules, and wearables.
HBM interposer, silicon bridge, and chiplet-based SiP assembly for AI, HPC, and data-centre chips requiring 2.5D/3D integration.
Multi-die SiP and Package-on-Package (PoP) integration with passive embedding, substrate stack-up coordination, and qualification.





Avecas operates as a turnkey OSAT partner, taking responsibility for the complete back-end flow so design teams can stay focused on silicon. From package selection and substrate design through die attach, interconnect, moulding, and singulation, every step is engineered to protect yield, reliability, and time-to-market.
Our portfolio spans the full assembly spectrum: fine-pitch wire bond for QFN, QFP, BGA, LGA, and CSP; copper-pillar and solder-bump flip-chip; Fan-Out Wafer-Level Packaging (FOWLP/eWLB) for thin, high-I/O devices; and advanced 2.5D/3D-IC builds with HBM stacks, silicon interposers, and silicon bridges. Chiplet-based System-in-Package and Package-on-Package integration support heterogeneous architectures for AI, HPC, and data-centre silicon.
Every programme is backed by AEC-Q100/Q101-capable qualification, JEDEC moisture-sensitivity and reliability testing, and full PPAP documentation with material declarations and lot traceability. Warpage, thermal, and mechanical-stress management are designed in from the start for large-body and multi-die packages, with SI/PI and thermal modelling at the co-design stage.
We plug in at any stage, from package feasibility studies to full NPI-to-HVM ownership, and coordinate a qualified fab, substrate, and OSAT partner network on your behalf.
The result is one team that carries your device from first build to volume production with consistent quality and predictable execution.
Assembly and packaging questions are common for teams evaluating outsourced OSAT or evaluating package options for a new device. Here are answers to the most frequent questions.
Avecas provides end-to-end OSAT services covering wire bond (QFP, BGA, LGA, CSP), flip-chip, Fan-Out Wafer-Level Packaging (FOWLP/eWLB), 2.5D/3D-IC with HBM interposers and silicon bridges, chiplet integration, System-in-Package (SiP), and Package-on-Package (PoP). We coordinate substrate design, die attach, interconnect, moulding, and singulation through to final test.
We support fine-pitch wire bond down to advanced bond pad pitches, flip-chip with copper-pillar and solder bumps, fan-out RDL, and high-I/O 2.5D interposer routing. Package families include QFN, QFP, BGA, LGA, CSP, WLCSP, FOWLP, and multi-die SiP/PoP stacks.
Yes. We run AEC-Q100/Q101-capable package qualification, JEDEC reliability testing (MSL, thermal cycle, HTSL), and PPAP documentation for automotive and industrial customers, with material declarations and traceability across the assembly flow.
Yes. We assemble 2.5D/3D-IC with HBM stacks, silicon interposers, silicon bridges, and chiplet-based architectures for AI, HPC, and data-centre silicon, including known-good-die handling, fine-bump flip-chip, and warpage/thermal management for large bodies.
We manage new-product introduction from package selection and substrate design through prototype builds, reliability qualification, and yield ramp into high-volume manufacturing across our fab, substrate, and OSAT partner network.
