Hi Hugo, If you pretreat both surfaces with HMDS you can get super glue to work for about an hour in 5% TMAH. -Mike >>> hugo.jazo@navy.mil 03/25/03 02:28PM >>> Hello all, Does anyone know of, or has experience with, an epoxy that is etch resist to TMAH? An epoxy would be the first choice, but I am open to other ideas like solder perhaps? The problem is, I already have singulated die so I cant deposit a film on the backside of the die for good eutectic or solder wetting.
