LOW CTE ELECTRICALLY INSULATING EPOXY
A dual or single-component, solvent-free product, ATE-26522 is an electrically insulating resin for protection of silicon die and electronic components. Adhesion to metals, ceramics and FR4 type substrates along with its thermal and chemical stability ensure good protection against environmental factors.
The consistency of the ATE-26522 is well suited for micro-dispensers and the reheology allows for good wetting of surfaces in contact with the resin. It also provides good adhesion to substrates. It is thixotropic, fast curing system offers high strength and thermal shock resistance form approximately -40ºC to 150ºC.
METHOD OF USE
The ATE-26522 resin can be supplied premixed and frozen, ready to use. It can be supplied in syringes designed to fit on the micro-dispenser, which has the advantage of avoiding handling operations which encourage the entrainment of air bubbles. When the product is supplied in pots (bulk), the resin should preferable be degassed for 15 minutes under a vacuum of less than 1mm of mercury.
As with most resin products, crystallization of the A side component can happen while in storage and can be returned to its original state without any performance and or quality loss by heating to 60ºC for 1-2 hours.
