Our company is experiencing cracked caps at our pick and place operations. The caps are being placed onto epoxy dots for subsequent wave solder operations. At present, be have set the pressure of the head at 2 in/lbs. This being down from manufacturers recommendation of 3.5 to 5 in/lbs. The caps appear to be chipping from the edge of the component toward the center, with the largest mass being chipped near the edge. If anyone has experienced similar problems, would you please contact me with your resolution. This is becoming very frustrating for us. Any help would be greatly appreciated.
