Electrostatic Damage Risk Assessment

New standards and customers require reliable indication of ESD protection levels in the electronic manufacturing and device handling process. With each Facility Evaluation, SH&A provides a detailed Human Body Model (HBM) Risk Assessment evaluation. This innovative approach was designed by SH&A to estimate the potential damage to ESD sensitive devices during handling and transport by operations personnel. The HBM Risk Assessment provides the following information:

The level of Human Body discharge damage protection offered in the process. This includes a probability analysis of device damage that may be caused by personnel discharge based on the sensitivity of various devices handled in that process.
A range estimate of overall personnel electrostatic voltages generated in the facility by operations personnel with greater than 99% reliability, including:

A range projection of body voltages generated by personnel while standing and handling devices at their workstations, and
During personnel transport of static sensitive devices and assemblies.

The assessment provides the answers Operation, Quality and ESD management need to evaluate the effectiveness of selected ESD controls. A detailed data summary and report is provided for each area of the facility where HBM Risk Assessment is conducted. Contact SH&A for further information regarding this valuable service.
