Our brushes come in many styles and sizes. Some surfaces, however, such as adhesive tape or plastic sheets, CAN attain intimate contact over a large area, and DO exhibit strong charging when they are simply touched to another surface and pulled away. If a charged dissipative material is grounded, charges will recombine at a slower rate until the object has no charge. The effectiveness of this corrective action was proven by subsequent testing of hundreds of thousands of RF IC packages in strip form with no QC electrical failures 0 PPM. On other laminate package strip designs, the solder balls are not all shorted together.
Steps were repeated on the three other cut strips.

This causes the air molecules in the vicinity of the point tip to ionize, which is known as the corona effect. Insulators can have both negatively and positively charged areas on the same object. Static Charge A static charge is generated between materials through friction, pressure or separation of two materials, one of which typically being non-conductive. During the singulation operation, ESD damage is not a potential issue as long as both the strip and singulation tool are grounded. One area of possible future work is to develop on-strip protection methodologies.
