Engineered for mass production of leadframe packages, the TOWA Y1E4120 Transfer Molding System executes robust transfer molding to encapsulate semiconductor dies. The cured epoxy layer shields delicate chip circuitry from humidity, particle pollution and mechanical damage throughout subsequent assembly and application.
Fine-tuned clamping force and resin injection control suppress voids and excess flash. Fast mold change capability reduces downtime, matching the needs of packaging facilities running mixed device types and continuous high-volume manufacturing.
