IXEPLAS Inorganic ION Capture Agent

IXEPLAS is a high-performance ION Capture Agent independently developed by Toagosei. Compared with conventional IXE, it offers greater ion-capture capacity and superior heat resistance. It effectively improves the long-term reliability of encapsulation materials and is also suitable for advanced semiconductor packaging and other applications with stringent ion-contamination control requirements, providing more stable and reliable performance for electronic devices.

Features

· A submicron material suitable for circuit-board encapsulation fillers and narrow-gap sealing. 
· Fine particles provide a larger specific surface area and excellent performance at low addition levels.
· Excellent capture of copper and silver ions; suitable for encapsulating copper bonding wires and silver wiring.
· A dual ion-exchange type that provides effective ion capture over a wide pH range.
· Low impurity content, with virtually no adverse effect on encapsulation materials.
· Contains no RoHS-restricted substances.

Mechanism

Finer particle size, lower addition level, higher efficiency.

Thanks to its ultrafine particle size, IXEPLAS delivers excellent ion-capture performance at a lower addition level than IXE.

Applications

· IC encapsulation materials (EMC, liquid encapsulants, underfill materials, and die-attach materials)
· FPC adhesives
· Solar-cell components (backsheets and encapsulation resins)
· Resist inks

Application Examples

● Suppression of copper-wire migration

· IXEPLAS provides excellent copper-ion capture and effectively suppresses copper-ion migration.
· Ideally suited for encapsulating copper bonding wires and copper wiring.
· Can also be used to suppress ion migration in silver wiring.

Test Conditions

· Epoxy acrylate + urethane acrylate resin: 98 parts; IXEPLAS-A1: 1.0 part
· Wiring width: 50 μm; wiring spacing: 50 μm
· Damp-heat bias test (85°C, 85% relative humidity (RH), 50 V; test durations: 500 and 1,000 hours)

● Corrosion-suppression test for aluminum wiring

· Adding IXEPLAS to encapsulation resin effectively suppresses wiring corrosion and improves package reliability.
· Because IXEPLAS has a fine particle size, only a small addition is required to deliver excellent performance.

Rate of Increase in Aluminum-Wire Resistance

· Adding IXEPLAS to encapsulation resin effectively suppresses wiring corrosion and improves package reliability.
· Because IXEPLAS has a fine particle size, only a small addition is required to deliver excellent performance.

Test Conditions

· Adding IXEPLAS to encapsulation resin effectively suppresses wiring corrosion and improves package reliability.
· Because IXEPLAS has a fine particle size, only a small addition is required to deliver excellent performance.
