284 Nanocoulomb Meter 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.
