Dear friends, I am looking for a diamond sawing blade to dice up the ceramic (alumina) wafers. I was using the disco diamond blade before, but the result wasn't good (that blade dies out very fast). Does anybody has the experience of dicing up the ceramic wafers? Does anybody know which blade manufacturers are good at ceramic dicing? My wafer sawing machine is DISCO DAD341. I need a ceramic dicing blade which is durable, accurate width tolorance and low chipping rate. Thanks!
