Title Proper : EPOXY RESIN SYSTEMS FOR LIGHT EMITTING DIODE
Note : This document is digital این مدرک بصورت الکترونیکی می باشد
Abstract : The objective of this project was to study the epoxy resins used inLED technology. Three epoxy resins were chosen in the experiment:D.E.R.-331 was a bisphenol A type epoxy resin, Eporite-5630 was abisphenol A type epoxy resin modified with an antioxidant, andERL-4221 was a cyclo-aliphatic epoxy resin. The curing agent wasMHHPA and the catalyst was TBAB. Thermal, mechanical, electrical,and optical properties of the cured D.E.R--331, Eporite-5630, andERL-422 1 were studied. It was found that ERL-4221 had outstanding UVresistance. But other properties of the cured ERL-4221 system weredecreased due to the internal stress generated during the curing process.D.E.R--33 1 showed better thermal stability, but the aromatic groups in themain chains caused photo-oxidation. Eporite-5630 has the advantages ofD.E.R.0331 and better W resistance........-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
