Slide 5: Gang Assembly
Gang Assembly RETAINING BLADE #1 SPACER BLADE #2 NUT Gang Assembly - Just as in any standard dicing operation the blade mount or flange set should be clean and free from burrs FRONT BACK or nicks before the blades FLANGE FLANGE and spacer are assembled. Gangs can be assembled off the machine or set
Slide 6: Initial Conditioning
Initial Conditioning Truing – The assembled gang should now be trued on a Silicon Carbide (SiC) block to ensure that both blades are cutting exactly at he same depth. Cuts may be made in a dummy wafer to check this because if one blade is cutting too deep it may weaken the tape and result in tearing
Slide 7: Operating Parameters
Operating Parameters Once truing is completed, operating parameters should match standard dicing parameters. Dicing tests showed that the dual gang wheel dicing approach is suitable for achieving the same feed rate as single wheel dicing, as well as obtaining a comparable kerf quality. Suggested Fee
