摘要	The effects of the geometry parameters of a ceramic cleaver on the morphology of ball and second bonded points were studied using an automatic wire bonder, push pull tester, scanning electron microscope, ceramic capillary with different geometric parameters and phi 25.4 mu mAg-5Au bonding alloy wire, etc. The result shows that when the inner hole diameter (IHD) of the ceramic capillary is 1.3 times the diameter of the alloy wire (33 mu m), the neck morphology of the ball bonded point (first bonded point) meet the requirements. The neck of the ball bonded point appeared to fracture when the IHD is 26 mu m; The neck of the ball bonded point appeared as an irregular shape when the IHD is 41 mu m. When the inner cutting angle diameter (ICAD) is 64 mu m, the size of the mashed ball diameter (MBD) is qualified. When the ICAD is 51 mu m, the MBD is too large and mashed ball overflows the pad. When the ICAD is 76 mu m, the ball bonded point is too high. When the inner cutting bevel angle (ICBA) is 100 degrees, the MBD size meets the requirements of the pad. When the ICBA was reduced to 70 degrees, the ball bonded point is eccentric. When the ICBA was increased to 120 degrees, the MBD is too large and is connected to the adjacent pad contact. The size of the fish tail of the second bonded point (second bonded point) changed in the same direction as the tip diameter (TD) changes. When the TD is 178 mu m, the fish tail shape is regular and symmetrical. When the working face angle (WFA) is 8 degrees and the outer circular radius (OCR) is equal to the diameter of the alloy wire (25.4 mu m), the fish tail shape is regular. When the WFA is higher than 11 degrees or the OCR is higher than 30 mu m, the fish tail will appear as virtual welding, and when the WFA is less than 4 degrees, the fish tail of the second bonded point will break due to thinning. When the OCR is less than 20 mu m, the fish tail of the second bonded point is too long and causes a short circuit.
