Definition
A semiconductor molding or encapsulation system meters and cures polymer around a die, wire-bond, flip-chip, wafer-level, or panel-level assembly while controlling fill, pressure, temperature, voiding, bleed, warpage, and contamination.
Process position
Inputs
- Assembled die and substrate
- Mold compound or encapsulant
- Mold and cure recipe
- Carrier or leadframe
Outputs
- Protected molded assembly
- Cure and pressure record
- Unit for trim, singulation, or test
How it works
- 01Precondition materials and assembly
- 02Load and close mold or dispense cell
- 03Fill under controlled pressure
- 04Cure through defined profile
- 05Demold, clean, and inspect
Role in the production flow
Encapsulation protects fragile interconnects and redistributes mechanical and environmental loads. Flow, cure shrinkage, adhesion, package geometry, moisture history, and the interconnect architecture determine the relevant defect mechanisms.
Packaging equipment that dispenses or transfers protective polymer around assembled semiconductor die and interconnects.
Boundary: The cited manufacturers document the equipment category and its intended uses; this record does not independently validate vendor performance claims or rank products.
Qualification and production boundaries
A qualified flow must specify package architecture, encapsulant lot and condition, fill path, mold and vent design, pressure-vacuum profile, cure, warpage, adhesion, void and flash limits, cleaning, and downstream singulation.
A qualified flow must specify package architecture, encapsulant lot and condition, fill path, mold and vent design, pressure-vacuum profile, cure, warpage, adhesion, void and flash limits, cleaning, and downstream singulation.
Boundary: Actual acceptance limits, recipes, throughput, availability, and ownership economics are product-, process-, site-, and contract-specific.
