Hello,
I have a small circuit board that is just several "high power" SMT LED's which require reasonably large copper pads on the board to dissipate the heat. This small LED board is about 1.5" long and 1" wide and fits inside a similarly shaped recess in the back of a plastic lens. It will be placed LED side down into the plastic lens and then I need to expoxy/pot the PCB into the plastic lens housing. The epoxy should be thick enough so that it doesn't run down the size of the PCB and interfere with the LED's. It should also be clear so that any drops do not show up as discolorations inside the clear lens. It also (ideally) have good thermal properties and help to dissipate the heat generated by the LED's. Of course it needs to be non-conductive and should hold up well to outdoor temperatures and be unaffected by contact with water.
Can anyone recommend such a beast? Or can anyone recommend a company I can contact who has a line of expoxies/potting compounds and see which one would work for me?
Thanks! Mike
