All solder balls are electrically isolated on each 23 mm x 23 mm x 2. A review of the RF IC strip test system revealed that the test chuck was designed to keep the strip-under-test electrically isolated from the handler ground. This will reduce the static charge on the surface. CSM withstand voltages are inversely proportional to strip capacitances. For a device with a relatively low CDM withstand voltage, the corresponding CSM withstand voltage for a large strip may be much less than V. Custom Antistatic Brushes Precision Brush.
The metal channel strip brush is the most commonly used for dissipating and wiping, or handheld toothbrush or pencil brushes for smaller area work.
Metal Strip Chip Resistors
Among other things, this acts to increase the total contact area. With the RF IC strip, the die attach paddles on all packages were connected together via tie bars and the common leadframe. Upon review, however, this is not surprising. The ESD film has excellent transparency, chemical resistance and good abrasion resistance. For example, the ordering of the triboelectric series is different when surfaces are rubbed together rather than simply touched.
