Thermoset ME-430 Board Level Encapsulant Where to Buy
Product Information
LORD Thermoset ME-430 encapsulant is a one-component, semiconductor grade epoxy designed for the encapsulation of Chip-on-Board (COB) devices. It is composed of 100% solids and formulated with high purity resins, fillers and additives to provide the ionic purity levels required for use in high-end microelectronic applications.
Thermoset ME-430 encapsulant offers good adhesion to both laminate and ceramic substrates, and can be used in demanding high-end, consumer printed circuit board and semiconductor applications.
Shelf Life
Shelf life is six months from date of manufacture when stored at -40°C in original, unopened container. Syringe must be maintained at -40°C in a vertical (upright) position with the dispense tip facing down. Do not store syringe on its side (horizontally).
This material is shipped and stored frozen. Consult handling instructions** for thawing.
