| | Our spec on voids is 30% ball diameter in the center. On the component to ball and pad to ball interface, we use 25%. To determine this spec, we asked around. I don't know of any studies that have been done to verify if this is OK | | | | Regard

I used one on SMT at a previous employer. Make sure that you have 3 zones of preheat. Make sure that your operators are trained. The airknifes are extremely difficult to set up properly. Don't use them on high mix lines. We didn't need them once
