Nagase ChemteX epoxy sheet encapsulant for hollow packages

Nagase ChemteX · Material properties and interface engineering

Purpose: Hollow/microstructured packages need intended cavities preserved while checking coverage and interface integrity.
Technical approach: Nagase ChemteX offers controlled-flow epoxy sheets and functional multilayer structures for complex/fine geometries.
Scope of use: The supplier targets hollow high-frequency devices, with roll, sheet and varnish forms; confirm grade and forming/cure process.
Limitations and open questions: These evaluation considerations are compiled by BLNKK from public information. They are not supplier guarantees or a mandatory submission checklist.
Scope and limitations
Do not assume interchangeability with transfer-mold EMC or universal void elimination. Thickness, flow/cure and cavity tolerances are unspecified; distinguish designed cavities from coverage defects.
What to prepare
BLNKK suggests preparing geometry/cavities, interfaces, supply form, thickness and forming history, with coverage, interface and reliability comparisons.
Confirm with the supplier
Confirm grade, flow/cure, equipment/process conditions, cavity preservation and adhesion evidence before representative-geometry trials.
Public evidence: The named page documents these capabilities but provides no full formulation or process window.
