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.
