Vacuum lamination methods for forming conformally coated articles having a preformed lamination layer conformally coated to or on an object such as an LED array are provided. These vacuum lamination methods utilize a single heating step to heat a middle portion of the preformed lamination layer to a flowable condition prior to the preformed lamination layer being conformally coated over the article, such as the array of light emitting diodes disposed on an inner portion of a first side of a submount wafer.

This invention relates to the use of a thermoplastic elastomer comprising at least one silicone ionomer in the formation of electronic devices.

Use of ionomeric silicone thermoplastic elastomers in electronic devices

A composition includes: (I) an alkenyl functional, phenyl-containing polyorganosiloxane, an Si&#x2014;H functional phenyl-containing polyorganosiloxane, or a combination thereof; (II) a hydrogendiorganosiloxy terminated oligodiphenylsiloxane having specific molecular weight, an alkenyl-functional, diorganosiloxy-terminated oligodiphenylsiloxane having specific molecular weight, or a combination thereof; and (III) a hydrosilylation catalyst. A light emitting device is made by applying the composition onto a light source followed by curing. The composition provides a cured material with mechanical properties suited for use as an encapsulant for a light emitting device.
