Model 284 Nanocoulomb Meter
Monroe Electronics Model 284 Nanocoulomb Meter enables the user to easily and accurately measure the charge generated on items such as
electronic components by triboelectric charging processes. Static charges can build up on lCs as they vibrate and slide in shipping tubes or on PC
boards as they move around in contact with protective packaging materials. Model 284 aids in the selection and evaluation of packaging materials when
performing triboelectric charge testing as outlined in the Electronics Industries Association Standards for ESD sensitive Items (EIA-541). Two
available interchangeable standard sizes of Faraday Cups serve most needs. Inner dimensions of these are 2 5/8" dia. x 2 3/4" deep and 5" dia. x 6 3 /4"
deep. Custom sizes are available on special order. In addition, individual areas of semiconductor components, MR heads or other small static
-sensitive devices may be examined to evaluate manual or automatic handling techniques Contact is made to individual leads via the tip of an ordinary 1X passive oscilloscope probe.
