Dear Sir,
I am looking for a casting epoxy for optoelectronic component. The
epoxy should have low moisture absorb rate and CTE less than 60 ppm.
The epoxy can be casted to form the lens and have good clarity and
light transmissivity.
In the market, the casting epoxies have very high moisture absorb rate
and high CTE due to less filler to be added to the epoxy for light
transmitting purpose. This will cause the serious popcorn when the
unit is going to reflow.
I appreciat than i can get some information from you.
