Product Description
OPTOLINQ TC-8020T is a high transmission, one component, optically clear epoxy molding compound that is specifically developed for emitter and LED encapsulation. Its excellent fluidity design aids it to become easily mouldable and processable while offering excellent package performance and durability. This is supported by its long term transmittance and post reflow reliability.
OPTOLINQ TC-8020T is a single component epoxy with superior adhesion performance, transmittance and stability at high temperatures. It is mainly utilised to package single color (monochrome) LEDs, 7-segment LED displays, compact LED indicators, monochrome ChipLEDs and photo-links.It offers good adhesion to Bismaleimide Triazine - BT substrates and metal leadframes, good flexural modulus, and excellent anti-reflow performance while also passing the stringent MSL 3/2A JEDEC requirements.
