ESD sensitive devices inside protective packaging may be exposed to high stress levels outside ESD protected area. ESD shielding bags are therefore tested with realistic stress levels by a system level ESD generator. The aim of this study is to estim

Electrostatic discharge sensitivity of integrated circuits is compared with electrical failure levels in electronics assembly. Electrical components with a low electrostatic discharge withstand voltage would be expected to have more electrical failur

Clam shells can provide better ESD protection than shielding bags. Energy coupling in a near field is generally reduced by preventing a direct connection, decreasing capacitive coupling, and increasing breakdown field strength. A properly qualified s

ESD control programs that are based on the standards IEC61340-5-1 and ANSI/ESD S20.20 are targeted to provide safer handling of electronic parts now susceptible to damage by electrostatic discharge. However, ESD failures have occurred in EPA even whe

Measurement of body voltage alone can result in erroneous conclusions in qualification of footwear and flooring systems in combination with a person. Measurement uncertainties should be taken into account. We have studied the time dependency and char

ESD control items are generally characterized by direct current measurements at certain voltage levels. Discharge resistance may, however, have a remarkable voltage and frequency dependency. We have assessed conductive polymers by comparing the resis

Electrical components with a lower CDM ESD immunity can require additional protection methods in manufacturing. Discharge current measurements and electromagnetic pulse detection gives valuable data for more detailed ESD risk assessments. However, bo
