We have a SMT part that has been adhered to a board using Loctite 3609. I can't find anything in the product specs. on how to release the bond to remove the part. Does anyone know?

Try by using hot air (narrow nozzle) blasting the chip body until it gets released.

Thanks, GS This is a SMT LCD device with a plastic housing; we need to save the part if we can. I'm afraid the localized heat will damage it so not sure if that will be safe.

Yes SWAG you are right, heat could be dangerous for the parts to be removed. Any way it is not so easy to remove epoxy adhesive (3609) once it is cured. By heating the adhesive (over his TG temperature)it gets softened and by using a mechanical pull force you could try to remove the LCD before it gets damaged.

Just my 0,01 cents
