Electronic Packaging, Thermal & Mechanical Integration
BGA/CSP/QFN, interposers, 2.5D/3D integration, heat paths, cold plates, TIMs, board support, vibration and enclosure interfaces.

Treat electronics as physical hardware: packages, solder joints, substrates, heat paths, mechanical supports, enclosures and environmental loads.
Technical coverage
The Level-2 index stays readable; depth moves into focused Level-3 technical pages with their own diagrams, documents and source assignments.

QFN, BGA & CSP
Leadless and area-array packages, escape routing, solder joints, assembly constraints and inspection implications.
Open technical route →
Flip-Chip & Wafer-Level Packaging
Bumps, redistribution layers, underfill and wafer/package processes that reduce interconnect length.
Open technical route →
Interposers, 2.5D & 3D
Silicon/organic interposers, stacked die, TSVs and dense multi-die integration.
Open technical route →
Thermal Paths & TIMs
Junction-to-case/board heat paths, spreading resistance, thermal interface materials and measurement concepts.
Open technical route →
Heat Sinks & Cold Plates
Air- and liquid-cooled hardware, interface pressure, flow paths and system-level heat rejection.
Open technical route →
Mechanical Support & Vibration
Board supports, stiffeners, fasteners, connectors, modal behavior and survivability under dynamic loads.
Open technical route →Documentation lanes
Public-facing knowledge is separated from internal engineering control and source-library notes.
